Your Marine Products Analysts Help You to Find Your Way Around Those Icy Waters

Raritan Engineering would like to keep you posted on marine products and also wants to show you the ropes for sailing in Siberia’s icy waters.

The otherworldly landscape of flat ice and consistent breeze makes Russia’s Lake Baikal in southern Siberia and ideal ice-sailing destination.

At over 5,000 feet deep, Lake Baikal is the deepest lake in the world and the largest by volume, holding approximately 20 percent of Earth’s unfrozen fresh water, more than all the Great Lakes combined. The lake formed from a rift valley in the heart of Siberia 25 million years ago. 

Proper ice sailing is best performed on smooth ice with consistent winds, conditions most often found along the so-called Ice Belt, between 40 and 50 degrees N. With its dry climate and extremely long winters, Baikal is basically ice-sailing nirvana. The vast landscape is raw, remote and unspoiled. It’s far off the grid. 

Because of such high speeds, conducting safe races is of the utmost importance. If a boat capsizes, hits a hole in the ice, or smashes into something, the skipper gets ejected and slides across the ice like a curling stone. 

Your Marine Products Experts Want You to Avoid Midrace Collisions While Out On the Frozen Water

Your marine products professionals know that to prevent midrace collisions, racers line up side by side, with half the fleet required to go left and the other half right. Courses are typically windward/leeward, with exclusion zones around the buoys to prevent kamikaze layline approaches. 

Sailing on the East Siberian Sea, this is the coldest day of our journey. The water temperature is 0 degrees, with only the salt in the water keeping it from freezing. But it is the humidity which is the problem as almost everything outside the pit is frozen: the deck, the shoots, ropes, sails, mast, camera, etc.

Most of our weather instruments at the top of the mast do not work, so we can only depend on the GPS and the digital weather models instead. 

On the satellite pictures we can see that we are very near to the ice edge. So we are very carefully and check the radar in a frequent manner. When we did see the ice edge, it was a big white stripe at the horizon with no end. 

I journeyed to Baikal to shoot a Waterlust film about how ice sailors are uniquely sensitive to Earth’s climate. As a scientist, I’m fascinated by their perspectives; many have been competing for three decades. The dramatic reduction in sailable ice throughout Europe during this time has greatly affected the sport, and the creep of global warming means that many sailors must travel farther north and east to find good ice.

Your Boat Toilets Experts Know All the Secrets of Harvesting Seafood From Your Boat

Raritan Engineering Company your boat toilets specialists would like to share with you these topics we thought would be of interest to you this month regarding how to become a master chef harvesting seafood from your boat. 

Your boat toilets analysts help get your own delicious ingredients by learning how to harvest local seafood from your boat.

Lobsters are supreme hiders, and I’m instructed to keep a keen eye out for the telltale sign of their long antennae, which peek out from hiding spots. Once I have one in my crosshairs, I’m to let go of the rope, dive underwater, lure the lobster out of its hole with the tickle stick and pop it in my net. 

Although long considered one of the most edible riches of the sea, lobsters aren’t the only shellfish that are fun to catch and tasty to eat. Folks with access to a boat and a coast can harvest a bevy of delicious sea life, such as scallops, shrimp, oysters and stone crabs, pretty much anywhere like I do in Florida. 

Loving the Lobster

I learn that cleaning a lobster is fairly simple: hold it by the torso and twist off the tail. Before chucking the thorax and head, Doug has me snap off one of the spiny antennae and demonstrates how to insert it into the bug’s bottom to easily remove the membrane and waste track and, voila, it’s ready to prepare for dinner.

To safely hunt lobsters, a minimum of three crew members is needed: one to run the boat, another to serve as the drag buddy and a third to spot the bugs. 

Go to and see how you can find more information as well as get assistance on boat toilets and on how to harvest seafood from your boat at Raritan Engineering.

Your boat toilets professionals know that lobsters are social creatures and prefer to live cramped together on natural shelves and holes, called “condos” by local divers, within coral and stony reefs. 

The law requires a lobster to have a minimum 3-inch-long carapace (the part of the shell covering its torso), which means it’s old enough to have reproduced for at least one season. If it measures up, chances are that bug may be getting toasty on your grill tonight. 

There are two lobster seasons in Florida: a mini season that runs on the final consecutive Wednesday and Thursday of each July and then an eight-month season from August 6 through March 31 the following year.

Searching for Scallops

Scalloping, often referred to as the “great underwater Easter egg hunt,” is an aquatic adventure suitable for all ages. All you need is standard snorkeling gear, a required dive flag, and a mesh bag in which to store your stash.

They’re easy for novice and veteran scallop hunters alike to spot. With unmistakable fan-shaped shells and hundreds of fluorescent beady blue eyes, beguiling temptresses beckon to be caught. 

Scalloping season in Florida runs annually from June 25 to September 24. Each person is limited to 2 gallons of scallops in the shell or 10 gallons per vessel per day.

Clawing for Crabs

In Florida, once scalloping season closes, the long-anticipated stone crab season rides in on its coattails. Considered by many to be one of the most heavenly delicacies of the sea, stone crabs are named for their natural environment — they usually seek shelter under big, flat stones in shallow rock piles and jetties.

Wear heavy gloves and dive using scuba or snorkeling gear; lift up large stones or use a hook to drag the crab out; then square off in a battle with your prey. Stone crabs generally aren’t swift, so try to nab one by the elbows coming in from around each side.

Unlike scallops, stone crab claws should not be put on ice because the meat will later stick to the shell. Instead, store them in a livewell or an empty cooler. Each person is allowed 1 gallon of claws per day, or a maximum of 2 gallons per vessel.

The Shrimp Dip

Although even professional shrimpers can’t accurately predict when shrimp will be most plentiful, full moons, outgoing tides, colder months, shallow, grassy flats, and areas near bridges with strong currents enhance your chances for this crustacean crusade. 

Like much marine life, shrimp are primarily dormant during the day and rely on moving about in the darkness of night as protection from their natural predators. 

On to the Oysters

Oysters are largely stationary mollusks, which makes harvesting them fairly simple from aboard your boat or wading in the water. 

A single oyster can spawn 100 million eggs each year that, once fertilized underwater with sperm, form free-floating larvae, which anchor themselves to hard surfaces, frequently on the shells of other oysters, and become known as “spats,” or baby oysters. 

Oyster shells have sharp edges, so be sure to wear heavy gloves. Using a metal, curved rake or oyster tongs, chip the oysters off the hard surface and put them in your bucket. 

So don’t forget these wonderful types of food that you can harvest from your boat, lobster, scallops, crabs, oysters, and shrimp. Don’t miss out on this opportunity.

Your Electric Toilets Professionals Say An OCS Isn’t The End of Your Race

Raritan Engineering Company your electric toilets specialists would like to share with you these topics we thought would be of interest to you this month regarding how to recover from an OCS. 

Your electric toilets analysts want you to refocus and follow these easy steps. It’s the ultimate bummer. The starting gun sounds. You’re in the front row and looking good. Then there’s another horn, the X flag and, after an excruciating wait, you hear your sail number on the VHF. You’re OCS, and you can kiss a good result goodbye. 

1) Stick to the game plan. So many times your electric flush toilet experts know the frustration of being OCS causes teams to completely abandon the prestart game plan. 

2) Work to get a clear lane. Sticking with the example above, your best opportunity to get to the left might be to clear yourself around the pin and tack back to starboard. You’ll be second row — or worse — but the separation from the boats that started properly may allow you to execute the plan. 

3) Get out of phase (with the fleet). If neither side is favored, look to find clean air by going against the grain: sailing on port when most of the fleet is on starboard, and vice versa. Your marine toilets electric specialists understand that sailing out of phase with the fleet will create separation and allow you to sail your boat at optimum speed. 

4) Minimize tacks. Hitting a corner is one way to reduce the number of tacks. But it’s a risky call. If you decide to be more conservative, make sure to limit your tacks to the bare minimum. Double-check your lanes and try to anticipate where boats ahead of you will tack.

5) Boatspeed. This may seem obvious; boatspeed is always important. But it’s easy to get discouraged or distracted when looking at so many transoms. Redouble your efforts and focus. Every ounce of energy needs to go into sailing the boat fast.

6) Focus on short-term goals. Turn your OCS into a positive. Establish short-term goals by looking one mark ahead. It can be difficult for everybody to put everything they have into hiking when it may all be for naught. 

Your Electric Toilets Experts Help You Recover and Make It To The Finish Line

You can find more information as well as get assistance on boat toilets and on how to recover from an OCS at Raritan Engineering.

As those pundits at the club and your boat toilets professionals will also tell you, a race is never over till it’s over and you’ve reached the finish line.

Agree what signals the bowman will use and especially whether he or she is calling distance sailing or distance perpendicular to the start line (see our 5 tips: bowman signals); most boats use perpendicular distance.

Discuss with the bowman before the start how hard you want to push the line. If you are a fast boat in the fleet and there is no clearly favoured side on the beat, you can afford to hold back a little and keep the risk down. If not and you must go left, it may be worth pushing things a little harder.

Sometimes, your no plumbing toilets analysts know that seconds before the start, you will know you’re in a bad position and are not going to get a good start however hard you fight for your gap. If you call it early enough, you can often make room to tack or duck back through the fleet and be away on port only a few lengths behind the leaders.

If OCS boats are not being announced, then somebody on board will need to make the call – ensure you have a clear process for this before you start, so a decision can be made quickly.

Although being disqualified is frustrating, sailing is a team game, so learn from it and bounce back – you may be able to discard that result anyway.

If you do join in, your OCS will be counted in your overall series score. It is possible to request redress for being OCS, but unless you are confident there is clear video evidence or you have credible witnesses from other boats it will be a waste of social time for you and the jury.

So don’t forget these simple steps in recovering from an OCS. 1) Stick to the game plan;  2) work to get a clear lane;  3) get out of phase with the fleet;  4) minimize tacks;  and 5) focus on short term goals.

via 5 tips: OCS (on course side) or over the line at the start – what should you do?

Light winds

Your ball valves experts know that many years ago I voluntarily turned my back on the most powerful aid to light wind sailing known to man – when I gave up smoking. Your ball valve dimensions professionals know that the world’s most high-tech wind indicators are crude and insensitive compared to the curling wisp of tobacco smoke. 

When ghosting along in a breeze that barely ruffles the sea surface and only just fills your sails, it’s all too tempting to sit back and drift on until things kick in again. 

However, sometimes we need to keep the knots up when the wind starts to become light. Perhaps it’s simply that we’re loathe to break the silence with the engine. 

Trying one or two of them may well mean that you can make port without reaching for the ignition.

1 – Understand the sea breeze

I used to skipper a lovely old 56-footer for a Swiss owner. Your 3 way ball valve analysts understand that he was every bit as methodical and organised as you would expect anyone from his country to be, planning his summer cruises in meticulous detail. 

One Biscay trip, in particular, was plagued by light winds.Every morning, we would leave early and drift for a few hours before switching on the engine to catch up with the owner’s ambitious schedule. 

Your Ball Valves Professionals Say That Understanding the Sea Breeze Is A Must

You can find more information as well as get assistance on marine products and on the top 3 ways to sail in light wind at Raritan Engineering.

Your marine products specialists know that the mechanisms that create local winds are many and varied. It’s worth buying a book – such as the RYA’s Weather Handbook – and reading up on them while you’re waiting for the wind to blow! 

Warm days

Your full port valves experts know that on warm days with light winds, from any direction, the wind within 5-10 miles of the coast will generally increase during the afternoon and die at dusk as the land heats and cools. Don’t rush breakfast – the sailing will almost always be better later on.

Spring and summer

In spring and summer, clear skies and a light offshore breeze at breakfast time are perfect conditions for a sea breeze. There will probably be a brief period of flat calm, but look out for puffy white cumulus clouds forming over the shore showing the beginning of the sea breeze circulation.

Sea breezes are strongest near the coast, but can be felt as much as 10 miles offshore.

2 – Use the tide

Light winds greet a regatta fleet leaving Cherbourg, where a well-known tidal eddy can add knots to your boatspeed

On both sides of Portland Bill, for instance, the tidal streams flow south for nine hours out of every twelve. There’s a similar effect along the northern edge of the Cherbourg peninsula, where anyone prepared to hug the coast can gain a couple of hours of west-going tide. 

Go as close inshore as you dare

Faced with a contrary tide, the general rule is to go in as close inshore as you dare. Even if you don’t pick up a back eddy or counter-current, the speed of the foul tide will be reduced in shallow water. 

3 – Use the tidal wind

Tidal streams don’t just carry you in the direction they happen to be flowing – they also create apparent wind. Imagine that you are hanging on a mooring in no wind, with a four-knot tidal stream.

If you are beating across the tidal stream, keep the tide on your lee bow to make the most of the tidal wind. On a cross-channel passage beating into a southerly wind, it would pay to be on starboard tack while the tide is flowing west, and tack onto port when the tide turns.

So don’t forget these helpful tips when trying to sail in light winds. 1) You need to understand the sea breeze;  2) you need to use the tide;  and 3) you need to use the tidal wind.

via How To Sail In Light Winds

Windsurfers and racing yacht skippers have long been aware that the heeling moment exerted on a yacht’s sail varies according to the relative density of the wind. Many a windsurfer has puzzled over why a 5.2m sail is quite manageable during the summer holidays in the Mediterranean but seems impossibly overpowered for the same wind speed in early December in the UK. 

The ‘weight of the wind’ is an old saying that, perhaps unusually, has more than a grain of truth, although it is a fairly small grain.

The effect will be compounded by the fact that moist air is less dense than dry air. This is because water vapour is a relatively light gas compared with oxygen and nitrogen – the main constituents of air. 

For a fairly extreme example, in the tropics with a temperature of 32°C and 90 per cent humidity, the air density is 1.14 kg/m3. In a northerly airstream around the UK, we might have temperatures of 10°C and 10 per cent humidity giving an air density of 1.25 kg/m3

Your Macerating Pump Professionals Knows That Sometimes Expectation Can Lead to Misunderstanding the Situation

However, your macerating pump specialists know that the expectation may lead to some misinterpretation of what is actually happening. An increase in wind speed from 14 to 15 knots will give an increase in force on a sail of more than 15 per cent. 

So, the reality is that there is ‘more weight’ in cold dry air than in warm moist air. However, around the UK during the sailing season in one area the variation in the ‘weight’ of the wind must be fairly small and masked by larger effects due to variations in wind speed and especially when there are convective gusts.

A practical corollary of the above is that wind turbines can generate more power at a given wind speed in cold climates than they do in warm ones.

Cold air is much heavier than warm air and this is the basis for much of what we call weather. Did you ever notice after taking a hot shower, that when you first open the door to the bathroom, the cooler air from outside the bathroom comes in at the lowest level? 

Why is cold air heavier than warm air? Cold air is denser than warm air. The molecules are packed closer together. The amount of water vapor in the air also affects the density of the air. 

You may have heard that a baseball or a golf ball will travel further on a warm, humid day than it would on a cold, dry day. Since the warm, humid air is less dense, the ball travels through it with less friction.

Which is the best way to sail downwind?

Your marine products experts know that downwind cruising can offer some of the most relaxing sailing of the season. Just ease the mainsheet, pole out the genoa, engage autopilot, mix a drink and let the miles tick away as a cooling breeze rolls across the transom.

You might start wondering, if progress is a little slow, whether you would be better off digging the spinnaker out of its home in the forepeak? Would the bothersome cat’s cradle involved in putting it up and the tricky business of gybing, potentially perilous for a couple, pay off in time saved?

These are questions that any cruising sailor might ask, but what is the answer? The likelihood of a boat identical to yours sliding past with a different downwind set-up, offering a direct comparison, is seriously remote, and two identical boats with two different set-ups: all but impossible.

How do we find out?

We spoke to Sunsail, which very kindly agreed to loan us three identical Beneteau F40s from its racing fleet in Port Solent. Each boat would be crewed by two, with a third onboard to take pictures and make notes.

Go to and see how you can always find more information as well as get assistance on marine products and on how to become a pro at sailing downwind.

Each boat would fly a different downwind rig and sail in the same wind on the same day to settle the issue. The criteria used to select the best downwind rig were speed, comfort and hassle.

The plan was to check wind direction on the day and set a distant waypoint dead downwind. The boats would start in a line, and the distance to waypoint was noted.

On the day, the wind was forecast to back from NW to W, and remain quite light at around 5-10 knots. With a knot of ebb tide under us, the apparent wind would reduce still further. It was also a baking hot day so a sea breeze looked certain to back the little wind we had even more.

How did it go?

There’s not enough wind to fill the sail but it’s set and ready to catch the slightest zephyr

We were off. Well, sort of – we made 3.3 knots over the ground with the wind 3.1 knots apparent. Our problem was, squared right off, we were not generating any apparent wind, or so little as to make no difference.

The cruising chute boat sails shallow angles in light airs, so progress is slow

At first we made ground over the asymmetric boat by holding a straight course: she had been 50 yards ahead, but by the time she came back on port gybe she was 50 yards astern of us.

Then the wind backed 45 degrees, freshened a touch, and had us sailing east instead of south-east, our advantage evaporated and even though our speed over the ground went up to 5.1 knots, the asymmetric boat was 200 yards ahead of us and the symmetric boat remained a quarter of a mile ahead.

Gybing was a controlled business, not a tremendous ordeal for two, and would have been quicker if we hadn’t rigged the afterguy, but it was the seamanlike thing to do. 

So don’t forget these reminders on how to become a pro at sailing downwind. 1) Always check the direction of the wind;  2) remember to set a distant waypoint dead downwind;  and 3) keep in mind that all boats will react differently, so get some practice in.

See Why Your Seacocks Professionals Say Performance Boaters Don’t Deserve the Bad Rap


Raritan Engineering Company wants to keep you abreast of how to keep safe while enjoying fast speeds out on the water.

Performance boaters have long taken a bad rap for being gold-chained, fat-walleted, egotistical blowhards who quickly swap a check for 2,000 hp marine missiles and menace the waterways.

Forget that stereotype. Today’s go-fast boaters are more cerebral, more competitive and less likely to assume they know it all. The prevailing attitude is that with speed comes responsibility. 

Apt Pupils

Jim Waters, a top-level Hollywood executive, is a longtime boater. He recently acquired a DCB (Dave’s Custom Boats) twin-engine catamaran. Faced with a more aggressive hull style and increased horsepower, he decided to seek out additional training.

“I was tired of that. I wanted to know more about how to handle the boat, dock it, launch and load it. I wanted to be more confident in my ability to take it out alone,” she said.

Scott was happy to see her take a more active interest in the sport, and wanted to be a better driver himself, so their week’s vacation at Desert Storm began with two days of instruction from Tres Martin and Brad Schoenwald, partners in the Ultra High Performance Course. 

Competition? After attending these classes, I also met up with Craig Barrie, vice president of sales for Donzi Marine and chief instructor for hands-on training aboard the Donzi 38 ZR Competition. 

Speed 101: Turning

Both classes began with basic boater safety training and the “Rules of the Road,” aka the International Regulations for Preventing Collisions at Sea, or Colregs. Before you can fly, you have to learn to walk.

Your Seacock Experts Help You Gain the Skills Needed to Be Safe While Going Fast

“That may be true for some boats,” Barrie said during our later tests, “but I set mine up myself and am confident in its turning ability.”

Your seacocks specialists ask, “how do you safely turn at speed?” Tres Martin has a special technique.

For both Barrie and Martin, setting up for the turn is as important to its flawless execution as actually making it. The steps are deceptively simple.

To set up or “get set,” do a head pan to check for other traffic. Pull back slightly on the throttle. Martin repeats again that he wants you under 70 mph before the maneuver.

In Martin’s turn, hands on the helm at 3 and 9 o’clock, he executes the turn by rocking the helm 180 degrees then returning to center repeatedly — that rotation changes depending on the steering ratio of the helm. 

“Now, if you want to turn sharper, add more speed.” It seemed counterintuitive, but as I added throttle, the boat arced tighter and I edged the speed up, keeping one eye on the tachometers — both holding steady at equal rpm.

What if one tach suddenly ran up to the red line — or worse, you felt the boat slip loose at the stern?

“Your escape plan is always go straight. Never yank the throttle back. Go straight, get control, then ease back to a comfortable speed and collect your wits,” Martin advised.

Even a PWC rider can tell you that the quickest ticket to instability is to suddenly stop the engine.

Performance 102: Holding Steady

With all the focus on turning, Barrie sees a lot of captains fail trying to maintain too much speed in a steady course. Running at speed is not just knowing how to work the controls; it’s about reading water.

“In performance boating, it’s not how fast you can go; it’s how long you can go fast,” he said. The most important thing when maintaining a course at speed is anticipating what’s happening on the water in front of you. 

“Sooner or later,” Barrie warns, “the boogie man will come. When you make a mistake and get caught, you usually know what you did before it happens.”

You won’t see the next wave coming — or you’ll change your grip on the helm on re-entry, feeding in rudder.

It’s that experience thing. Like with Jim Waters in his DCB.

Stepping to the dock, Shellie gushed to her husband, “You’re gonna be givin’ up some throttle time, Scott.”

Maybe the schools need to add another class topic that dates back to kindergarten: learning to share.

Your TruDesign Experts Know Great Antifouling Paint Is Vital for Peak Performance 

Raritan Engineering Company your TruDesign professionals would like to share with you these topics we thought would be of interest to you this month regarding the best antifouling paint solution for you.

Your TruDesign analysts know that if your boat stays in the water at least part of the year, good antifouling paint is critical for keeping it performing its best, and for reducing fuel costs. Most boaters find bottom painting messy and tedious, but it’s one of the key preventative maintenance jobs that keep your boat in shape. 

Antifouling paint keeps marine organisms, taking the forms of shell (animal fouling from barnacles and zebra mussels), weed (plant growth) and slime (single-celled algae) from attaching themselves to your boat. 

Choosing an antifouling paint is regional, as boaters in the Great Lakes, Pacific Coast, Southeast, Gulf Coast and other regions tend to choose similarly to their neighbors in the local marina. 

Do you want bright colors?

Use paint with copper thiocyanate, zinc or ECONEA biocide. White copper (cuprous thiocyanate) is clean white in color and used in Pettit’s Vivid and Interlux Trilux 33. It requires 50% less content than the heavy, dark copper used in conventional antifouling paint. 

Are you in an area that restricts copper biocides?

Use a paint with zinc or ECONEA biocides.

Go to and see how you can find more information as well as get assistance on TruDesign and on the best antifouling paint solution for you at Raritan Engineering.

Non-biocide paints—foul release coatings: Biocide-free foul release coatings are just beginning to be available to recreational boaters, used on propellers in products like the popular PropSpeed. 

Do you want to haul out over the winter and relaunch without repainting?

Use copolymer ablative type paint. Copolymer paints release biocide at a constant controlled rate throughout their lives, wearing away or “ablating” much like a bar of soap. Paint wears off faster in higher drag areas on the hull and appendages.

We recommend a covering of two or three coats on the first application. Copolymer paints with anti-slime additives are best for heavy fouling areas. Environmentally preferable: CFA Eco, Ultima ECO and Pacifica Plus are ECONEA-based copolymer ablatives.

Are you going to be using a vinyl-based paint?

Make sure you remove the old paint film unless it’s also vinyl based.

Are you in saltwater or freshwater?

There are specific paints that are recommended for freshwater, and some paints that are specifically recommended against freshwater use.

Do you use your boat often or infrequently?

Frequently used boats may want to use an ablative paint, which will get smoother over time and will shed light growth. Infrequently used boats may want to use a modified epoxy paint that will have good antifouling properties when the boat is inactive.

If you keep your boat in the water year round you are most likely a candidate for a high-copper-content modified epoxy paint that prevents growth by leaching biocides upon contact with water. Contact leaching paint releases the biocide at a steadily decreasing rate, leaving the hard coating of the original thickness at season’s end.

Are you painting over old paint?

Three general rules:

  • Make sure the old paint is firmly attached. Don’t put good paint over loose, flaky paint.
  • Don’t apply paint over old paint that contains a slippery Vinyl or Teflon agent
  • Don’t apply a hard paint over a soft paint.

Help for the Do-It-Yourself Painter

For more information on for the do-it-yourself boat owner on how to prep your boat’s bottom and apply antifouling paint, see our West Advisor and companion video called Do-It-Yourself: Bottom Painting.

So don’t forget these helpful reminders before buying your antifouling paint solution. 1) Do you want bright colors?;  2) are you in an area that restricts copper biocides?;  and 3) are you painting over old paint?

 Marine Head Units Experts Show You How to Change Out Your Trailer Tongue Jack

Your Marine Head Units Specialists Recommend Changing Out Jacks With Frequent Usage

Raritan Engineering Company your marine head units analysts would like to share with you these topics we thought would be of interest to you this month regarding how to change out your own trailer tongue jacks.

Your marine head units experts know that I go through a heavy-duty trailer tongue jack every three to four years. Corrosion, frequent use, and a hefty boat and trailer take a toll on these jacks, so I have become adept at changing them out. 

Sometimes the jack gets broken when boaters forget to raise it after they hitch up the trailer; it drags on the pavement and becomes damaged.

Getting Started
Skill Level: 1.5/5
Time to Complete: 1 Hour

Tools and Supplies
* Fulton 2,500-pound square-tube tongue jack ($78.99,
* Floor jack
* 6-by-6-inch wood blocks
* Jack stands
* 3-by-3-foot sheet of ½-inch plywood
* Box/open-end wrench set
* C clip pliers ($15.99,
* Reciprocating saw (to cut off rusted bolts)
* Safety glasses
* Marine grease

Changing Out a Trailer Tongue Jack

1. Use a Floor Jack

If the tongue jack goes kaput while the trailer is hitched to a tow vehicle, don’t stress. Your best marine head unit professionals know that you need to park the boat and trailer in their storage location and chock the tires. Use a sufficiently rated hydraulic floor jack to lift the trailer coupler just high enough to clear the tow ball. 

2. Support the Trailer Tongue

Place a sufficiently rated, adjustable jack stand under the trailer tongue, making sure it rests square and level under the metal tube that forms the trailer tongue. Your waterproof head unit analysts know that a piece of plywood under the stand will keep it from sinking into gravel, soft soil or turf.

Your Marine Head Units Professionals Remove the Anxiety of Changing Out Your Own Jacks 

3. Remove the Broken Tongue Jack

With the trailer properly supported, you can remove the old tongue jack. Your TruDesign specialists understand that jacks that bolt to the tongue or trailer frame are fairly easy to remove with a couple of wrenches, assuming the bolts and nuts that secure the jack are not badly rusted.

You can find more information as well as get assistance on TruDesign fittings and on how to change out your trailer tongue jacks at Raritan Engineering. 

4. Attach the New Jack

To keep installation simple and quick, buy the same model tongue jack as the one you are replacing. Your marine head experts say that this way you know it will fit, is sufficiently rated to support the tongue, and won’t create clearance issues, which is important with swing jacks. 

5. Raise the Tongue

With the new tongue jack installed securely, you can now use it to raise the trailer tongue enough to remove the jack stand(s). To keep the tongue jack working for as long as possible, grease the gears at the top of the jack and lightly coat the telescoping arm with grease. 

Feet and Wheels

Telescoping tongue jacks come in a wide range of styles and weight ratings. Most jacks with ratings of 2,500 pounds or more dispense with pivoting mechanisms and wheels, which become weak points when supporting heavy tongue weights.

So don’t forget these helpful pointers on how to change out your own trailer tongue jacks. 1) Make sure to use a floor jack;  2) support the trailer tongue;  3) attach the new jack;  and 4) raise the tongue.

Assume the Position: Two boats get in position around a rock jetty, fishing both the point and steep drop-off. Not all passes are this calm and uncrowded, especially on the weekends.

If inlets and passes are the main thoroughfares for game fish to and from the ocean, jetties represent that one exit with all the restaurants. Rocky breakwaters are a veritable buffet table for species like striped bass, flounder and redfish. Even with pesky boat traffic, ocean swells and nearby shoals, these pervasive fishing structures remain popular for boat and shore fishermen. I went to five experts to learn how they avoid common jetty blunders and out-fish their close-quarter compatriots.

Don’t Let Your Presentation Stray from the Rocks

Even when fishing off the jetty, keep your presentation close to the structure for more hookups.

Capt. Alan Pereyra, of Topp Dogg Guide Service in Galveston, Texas, targets the jetties of the Galveston Ship Channel all year long for a variety of species. The Ship Channel is one of three cuts into the Galveston system, the other two being Rollover and San Luis passes.

“In the summer we’ll catch redfish, speckled trout, sheepshead, black drum, Spanish mackerel and sharks,” he says. 

Depending on the tide strength, Pereyra might use a kayak anchor in light current to hold the boat in place. “For heavy current,” he says, “I’ll drop a Danforth boat anchor 20 to 30 feet from rocks, then let [rode] out to position the back of the boat close to the rocks for my customers.”

Your Marine Heads Experts Suggest That You Follow These Casting Tips

Once at the rocks, he’ll use light setups with live shrimp for a ­natural presentation. “I want the bait to flutter down toward the bottom as it flows with the current,” says Pereyra.

Don’t Handcuff Yourself to a Single Bait Species

Your marine heads specialists and most captains strongly recommend casting near the rocks.

Having a variety of baitfish in the livewell can be paramount to enticing the bite, says Capt. Jared Simonetti of Clearwater, Florida. He regularly fishes the passes from Anclote Key to the Skyway Bridge for snook in the summer months.

“During the incoming tide, I’ll use leader as light as 30-pound-test and free-line the baits along the jetty,” he says. 

“These baits I send to the bottom using weighted rigs with heavier 50- to 60-pound leader,” he says. Simonetti wants the resilient baits to get down to the staging snook when the water ­visibility drops.

Don’t Forget the Jigs

“I call it the best rock pile on the coast,” says Capt. Trevor Smith of ProFishNC Charters, referencing Masonboro Inlet’s pair of jetties. 

“On the last two hours of the ­outgoing, when the bait dumps out with the backwater tide, I’ll use 3- to 4-ounce 5-inch-long metal jigs,” says Smith. 

Red drum and cobia are available in the springtime, with May to June hot for cobia, says Smith. August to October brings an influx of bull reds.

Don’t Stop Fishing When the Sun Goes Down

Stripers attract fishermen in droves to the jetties each spring and summer. Stay out after the sun sets and experience an even better late-night bite.

Delaware’s Inner Wall and Outer Wall skirt Cape Henlopen at the southern cape of Delaware Bay. The Harbor of Refuge Light sits atop the outer breakwater, while the East End Light marks the inner breakwater. 

Capt. Chuck Cook, of First Light Charters in nearby Lewes, Delaware, heads to these hot spots when the moon shines bright at night. “Bluefish take over in the evening and morning hours, but it’s a 100 percent striped bass bite at night,” he says.
