Your Marine Sanitation Device Suppliers Share Further Need-to-Know Tips for You and Your Crew

Raritan Engineering your marine sanitation device distributors would like to share with you this week some great information regarding potentially life saving tactics for getting through tough summer squalls.

Summer is here and the time is right . . .  for testing your squall-busting tactics.

The comparison of jibe-taming devices in the July 2017 issue of Practical Sailor is an appropriate topic for the summer when afternoon squalls so frequently add a little excitement during the leg back to the marina, or the approach to the next anchorage. 

The ideal sail plan for dealing with squalls will vary by boat, visibility, sea conditions, and intensity of the squalls. Ideally, the helm is still relatively well-balanced and responsive for whatever point of sail you choose.

Our gaff-rigged ketch reefed down with a double- or triple-reefed main and staysail could handle about anything and still keep moving on squally night, but our main was easy to scandalize (dip the gaff) if the gusts were particularly intense. 

While every squall is different, there are a few rules of thumb that can help guide your decision-making process. Your marine sanitation device suppliers discuss how the following bits are culled from my own experience and a couple of weather books I’ve found helpful over the years, Bill Biewenga’s “Weather for Sailors,” and David Burch’s “Modern Marine Weather.” 

If you are the type who benefits from seminars, look for those offered by former NOAA forecaster Lee Chesneau (www. marineweatherbylee.com), author of “Heavy Weather Avoidance.”

Your Marine Sanitation Device Professionals Further Discuss the Importance of Always Being Alert

Squall Tips

Keep in mind, there are plenty of exceptions to these rules of thumb—but as Burch puts it, you have to start somewhere.

  1. Taller clouds generally bring more wind.
  2. Flat tops or “boiling” tops can bring brisk wind speeds and sudden wind shifts.
  3. Slanted rain generally indicates there is wind. Squalls often move in the direction of (or sideways to) the slant, so don’t assume that the cloud is “dragging” the rain behind it, as it might appear.
  4. Track cloud/storm movement by taking bearings on the center of the storm (not the edges).
  5. Watch for whitecaps below the clouds, indicating strong gusts.
  6. “Tilted” clouds often bring wind.
  7. The first gust, usually a cool downburst, can strike one-to-two miles before the cloud is overhead, and before the rain starts, so reduce sail early.
  8. The strongest gusts and the increased wind accompanying the squall generally blow in the direction of the cloud movement, i.e. outward from the “front” of the cloud. However, increased wind blows outward from all sides of the cloud.
  9. Squalls do not necessarily come from the direction of the mean ambient wind, so squalls to weather are not the ones to worry about. 
  1. The strongest wind comes with or just before the light first rain. If the squall arrives already raining hard, the worst winds are usually past, but strong gusty winds are still possible.
  2. Behind any squall is a unnerving calm.
  3. If you are faced with a number of successive squalls, they will often follow a predictable pattern, allowing you to fine-tune your tactics.
  4. If you plan to bathe in the downpour, go easy on the shampoo—you might not get enough rain for a rinse.

Your Marine Ice Makers Distributors Share Crucial Sailing Strategy With You Today

Raritan Engineering your marine ice makers specialists would like to share with you these topics we thought would be of interest to you this month regarding how to avoid having tunnel vision while competing.

Dang it! We’ve all been there. You just had to cover that one competitor, no matter which way they went. Your marine ice makers professionals further discuss how you just had to follow the local knowledge, high-tailing it to one part of the course. You just had to tack immediately off the start, to set you up for the right hand shift the weather forecast said was coming. 

Oops. It didn’t work out.

While the classic version of sailboat racing’s “tunnel vision” is focusing in on one competitor and letting a whole pack sail by, tunnel vision or hyper-focusing on one element can affect several parts of our sailboat racing game.

This complexity can be befuddling. To overcome the complexity, it is easy to oversimplify—just picking an “answer” and going with it. While often keeping it simple is sufficient, to excel, it is important to let yourself think about multiple layers of information and then make decisions. What are some of these information potential pitfalls, and how do you avoid them?

Boat setup.

Most one-design boats give sailors the ability to adjust certain elements of the way the boat is set up, to enable a range of sailing weights and styles. How tight are your shrouds? How long are your spreaders? Important questions and they don’t have the same answer for every team.

You can always find the best marine ice makers here at Raritan Engineering, where we always take care of your marine sanitation supply needs.

Instead of just copying settings, seek out people who will talk with you about why they choose the settings they do, and then figure out (and test) what is right for you. Your marine ice makers manufacturers share how the same thing with sails and boat setup: different teams may want to have the vang led differently or to use a fuller main. Use what’s right for you.

Sailing conditions.

Local knowledge can be a great reference, but it’s not the right answer 100 percent of the time. While the locals may all say, “you’ve got to go left,” it’s important to keep your eyes open.

Tracking actual observations—informed by weather forecasts and local knowledge—is a better blend of information.

Tactics/strategy.

It is so easy to get sucked in on this one. Maybe you’re having a good race, and you’re actually leading one of the top guys in the fleet out to the left side of the course.

You’re now DFL and second-to-DFL. The times when you want to focus solely on one boat are incredibly few and far between and generally involve being the last race of a regatta when you’re within a few points of only one boat. Otherwise, keep your options open.

In closing.

It is difficult to find and keep the right perspective—let yourself focus, but also be open to doing things differently. Keep your eyes and ears open, and welcome new and different information. If you’re more receptive to changing situations than your competitors are, you’re sure to make smarter, faster decisions.

Marine Hot Water Heaters News Dept Says: Ark. Teen Shares Story of Boating Accident In Hopes She Can Save Lives

July 29 of last year was supposed to be normal day on the lake for Jodi Brashers, until a boater changed her life forever.

Brashers said she was swimming just a few feet from her friend’s boat when she saw another boat headed straight towards her at about 50 miles per hour. She said the boat had no signs of stopping.

“When we saw it, we were yelling and waving,” she recalled. “I was swimming towards our boat, and when I realized I couldn’t make it to our boat, I went under water. I ran out of breath and my life jacket pulled me back up, and when I came out of the water, the boat hit me.”

Her whole body was sliced open, and she thought she was going to die.

“When we got to the boat landing, I kept saying I’m dying get help.”

Her heart stopped once on scene.

“They gave me CPR, and I came back alive. When I died I saw God and my dad. That’s how I tell people God was with me, because my dad was standing there above me,” Brashers said.

Next thing she knew she was in Little Rock, then she blacked out again and woke up two weeks later in the hospital. She was fighting for her life, surgery after surgery. She was there for three months and one day until she was finally allowed to go home.

She was starting to cheer up, until life knocked her down yet again: the doctors told her that she would never be able to walk again. But, she said she was determined to prove them wrong.

She can now walk with the help of a walker or family member and hopes soon she won’t need any help at all. It’s been a yearlong battle in and out of the hospital. She’s undergone 35 surgeries and still has many more.

Brashers said she was saved for a purpose and that purpose is to share her story and spread awareness for boating safety.

“Accidents do happen whether it’s in a car or in a boat,” she said.

Her first awareness post now has over 25,000 shares and more than 10,000 likes. She hopes her post not only brings awareness, but helps people going through hard times, hoping to show them they’re not alone.

“Some days I look at my legs and think, Wow I’m covered in scars. But, I look at my scars like they’re battle wounds. I won a war against a boat,” she said.

Brashers said what has helped her the most is telling herself she can do anything, but she just has to do it a little bit differently.

Your Macerating Pump Suppliers Discuss Advice That Could Affect Your Next Sail Purchase

Raritan Engineering your macerating pump experts wold like to discuss with you these topics we thought would be of interest to you this month regarding the possible need to switch to polyester sails.

The Arcona 400 trucks to weather under state-of-the-art load-path sails from UK Sailmakers. The durable crosscut laminate sails use a scrim of Spectra fibers with carbon tapes and panels that are glued together.

Arcona Yachts

One of the largest expenditures a cruising sailor will ever face is upgrading the yacht’s power plant. Not the one under the companionway—the ones set off the mast. 

Your marine toilets electric specialists discuss how that in the United States and abroad, four major suppliers of sailcloth—Dimension Polyant, Bainbridge International, Challenge Sailcloth, and Contender Sailcloth—provide sailmakers with Dacron and laminate cloths and related materials to build strong, state-of-the-art headsails and mainsails.

Reliable, Affordable Dacron

Obviously, high-tenacity Dacron makes better cruising sails. The cost difference between a “value” cloth and a “premium” one, both from the same supplier, can be significant, close to 100 percent for some 8-ounce Dacron fabric that I’ve seen ($7 per yard versus nearly $15 per yard).  

Crosscut construction wastes very little cloth and is the fastest way to fabricate a sail; the seams between panels also offer many opportunities to design shape in the sail. Your marine head plumbing distributors talk about why the vast majority of modern boats use Dacron sails.

Recently, Challenge Sailcloth developed a Dacron product for use in radial-panel layout. North Sails also has its own version of Dacron, called Radian. In both materials, the warp, or long yarns, are or should be thicker than the fill.

Understanding Laminates

Laminated sails were first introduced in the early 1970s. The Australian 12-Meter Southern Cross tried using Kevlar fibers laminated to film and built as a crosscut sail before the 1974 America’s Cup. These early attempts at laminated sails proved to be unreliable—they were prone to break without notice—and were never used in competition. 

Your Macerating Pump Specialists Give Great Pointers On Choosing the Right Material For Your Sails

Different sailmaking styles and cloths are evident in this trio of racing and cruising boats under way. Doyle’s Stratis pre-impregnated fiber technology is employed in the load-path sails on a Hanse 630 (left).

Macerating pumps can be seen here at Raritan Engineering. Check out why we are the best solution to your marine sanitation supply needs.

Historically, laminated sails of any construction method were usually replaced when the fibers delaminated from the film or the film itself broke down. 

Load-Path Sails

Prior to the late 1980s and the introduction of North’s 3DL sails—so-called molded sails—sailmakers and cloth manufacturers were working on their own versions of what has become known as load-path or string sails, which is the other way of making a laminate fabric. 

Scuttlebutt editor Craig Leweck reached out to North Sails Market Segment Manager Bill Fortenberry, who he coincidentally taught to sail a long, long time ago, for an update on this new product.

Is this making sailing more expensive?

No. 3Di NORDAC is making sailing more enjoyable. It is well known that you can buy an inexpensive cross-cut polyester sail. What is equally well known is the poor value inexpensive cross-cut sails provide. This matters even with heavy displacement cruising boats.

Are cross-cut Dacron cruising sails still an option?

Yes, we still offer cross-cut premium Dacron sails. We expect over time there will be less demand for sails made with the ancient process of weaving fibers into canvas cloth and sewing together panels.

Will 3Di NORDAC be used for keelboat One Design classes that require Dacron?

At some point in the future, it may be possible to adapt 3Di NORDAC for One Design class racing, but to date it has been engineered for cruising.

For the cruiser/racer boat that is used for both, is 3Di NORDAC the choice?

For any sailor looking for a dedicated racing sail, their first choice should be a sail with higher modulus material such as aramid or carbon, which both feature more resistance to stretch. Your marine parts supplies manufacturers share information regarding why polyester fiber stretches more than aramid fiber.

If a local PHRF area gives a “white sail” credit, would 3Di NORDAC qualify?

It is hard to know how local PHRF boards will treat a 3Di NORDAC sail. Technically there is no reason it would not qualify for a cruising sail credit. The sails are 100% polyester, they are not laminates, there is no Mylar, and they are engineered to weigh the same as a comparable Dacron sail and they are priced affordably.

Your Marine Hose Experts Offer Great Tips On Knowing When to Go Slower or Faster When Out On the Water

Raritan Engineering your marine hose suppliers would like to share with you these topics we thought would be of interest to you this month regarding the benefits of changing speeds.

Your marine hose specialists give explanation as to why the goal of a sailboat race is to beat your competitors to the finish line, so going full speed ahead is usually the best strategy. However, there are a few places on the race course where sailing slower may actually be faster. The leeward mark is one of them.

When you exit from the leeward mark, you want to be at least slightly to windward of the centerline of the boat ahead so you have the option to keep sailing straight ahead in relatively clear air. In order to do this you must:

• Be 100% ready to race upwind before your bow gets to the leeward mark;
• Swing wide before the mark so you can pass very close to it (you should be able to reach out and touch it);
• Be going fast (faster than your close-hauled speed) when you get to the mark so you can use this speed to pinch up slightly above the boat ahead.

1) If you misjudge your speed or if the other boat slows unexpectedly, you could hit them in the transom. Often the only way to avoid fouling is to bear off below them (which puts you right in their bad air).

2) The closer you are to the boat ahead, the more likely you are to be in (or fall into) their wind shadow.

There are several advantages to creating this gap.

First, it reduces the risk of catching up to the boat ahead, which means you won’t have to avoid them by bearing off into their bad air. Second, it allows you to accelerate as you approach the mark (rather than slow down which is often the case when you’re afraid of catching up to the other boat).

Don’t forget to look at your marine products choices here at Raritan Engineering. We always take care of your marine sanitation needs.

In most cases faster is better, but don’t be afraid to slow down when this tactic gives you more options and better control of your situation.

The basic concept of going fast-forward in a lift, or pinching in a header, has been around for as long as I can remember-or at least since my junior sailing days when my instructor passed along this tactical tidbit along. 

Understanding how to set up your sails to allow for a fast-forward mode is especially important in one-design sailing. This means understanding how to twist your sails, and knowing the difference between reaching and going fast upwind. 

When and where on the racecourse is it best to try and gain bearing? There are many different situations, but generally I’m looking to go fast-forward when I know I’m lifted and leveraged near a corner. 

A bearing gain comes from the twist and setup of the sails, but it also comes when the rest of the fleet is positioned on the outside of a shift or stuck in traffic. 

And here’s another one: “Wind direction of 180. Target speed is posted target.” In this case, the sails are set in a normal upwind mode with normal twist profiles.”Wind direction is 175, 5 degrees left of average. Target is top speed. Happy to be two-tenths under posted target speed.”

It’s critical to be aware of what you’re doing when you’re going for a bearing gain because you do not want to spear off into a corner, potentially sailing extra distance for a shift that never materializes. 

When to sail high and slow

First and foremost, I try really hard not to sail in headers. Rule No. 1, sail the lifts, makes life much better. But if you find yourself out of phase, you need to know how to sail the boat two-tenths under target for a period of time. 

In a venue such as Long Beach, Calif., where the locals know to head toward the right side of the racecourse after the sea breeze fills, sailing in high mode is imperative. 

Understanding your tactical needs at the time should be the driving factors in selecting any given mode. If you make the decision to go fast-forward, everybody on the boat needs to understand what you’re going for at the time and why. This will allow for a constant stream of feedback of performance versus competition so you will know when to change modes.

Raritan Marine Water Heater Distributors Talk About Cheap Ways to Keep Your Gelcoat Looking Great

Raritan Engineering your marine water heaters experts would like to share with you this week some amazing suggestions regarding how to restore your gelcoat. 

We’ve just wrapped up a test of aggressive rubbing compounds for heavily oxidized fiberglass hulls—now available to subscribers in the April 2014 online issue—and this also gave us an opportunity to look at the tools and techniques involved in resuscitating a neglected hull. Although this can be tedious work, it is one of those jobs, like varnishing, that offers instant gratification. 

Restoring old gelcoat is a matter of degrees. You’ll need to inspect the health of your gelcoat and decide which solution is best for you. If restoring the hull requires wet-sanding or rubbing compound, the general rule is to start with the least aggressive approach. 

If the gelcoat is deeply scratched, gouged, or looking thin in some areas, it may be time to sand and paint the hull (PS, December 2012, February 2011, August 2009). Remember that gelcoat is only a thin layer to begin with—it varies from boat to boat, and it’s thinnest at the bow, corners, and curves—and an aggressive buffing compound may take that layer down to fiberglass. 

Marine Water Heater Suppliers at Raritan Give Good Reasons to Invest In A Great Looking Gelcoat

Your marine water heaters specialists explain how if oxidation and minor scratches are your problems, a rubbing compound system (followed by a wax) should be enough to restore shine. However, if the rubbing compound is getting you nowhere (try a test patch), and after washing the rubbed area, the oxidation is still visible, it’s time to wet-sand the hull. Assuming, of course, you’ve got enough gelcoat to sand.

Follow the wet sand with a fast-cut, coarse-grit rubbing compound. This can be followed by a medium- or fine-grit compound; if the boat is less than three years old or the oxidation is only mild, you can go straight to a medium- or fine-grit compound.  

Boat Buffing Techniques and Tips

Wet sanding: Start with 600- to 800-grit wet-dry sandpaper. Pros we talked with prefer Sunmight (www.sunmightusa.com), 3M (www.3m.com), and Mirka (www.mirka.com) sandpapers; they don’t load up as quickly and last longer. While you can wet-sand by hand using a rubber block, we suggest using a pneumatic or electric, dual-action (DA) orbital sander to make the job faster. Nelson Roberts of Atlantis Boatworks (www.atlantisboatworks.com) in Sarasota, Fla., showed us his coveted sander, a pricey device made by Mirka, which has developed an alternative to pneumatic and heavy electric tools. 

Compounds: Apply the compound generously to the buffing pad, keep it wet, and go slowly. If you don’t feel any drag on the pad, and it’s sliding around during application, it’s time to clean or change the pad. 

Compounding Tools

A successful refinishing job is the result of using the right products and the right tools. We recommend using a machine polisher for applying rubbing compound. In PS Editor Darrell Nicholson’s previous blog post, “Waxing and Polishing Your Boat,” he talked about a few tools, including the one he uses for big jobs: the DeWalt DW849, a Dewalt variable-speed polisher. 

Wool buffing pads are better than foam or cotton because they hold the rubbing compound better. Quality pads can last years. To reuse a buffing pad, wash it in a clothes washing machine using warm water; we suggest doing this at the laundromat.

Your Electric Toilets Professionals Share Great Pointers Before Buying Your First Power Boat

Raritan Engineering your electric toilets distributors would like to share with you these topics we thought would be of interest to you this month regarding the popular boats out on today’s market. 

Your electric toilets suppliers continue the discussion regarding how coastal surfers are seemingly on a continuous quest to find the perfect wave. Wakesurfers, though, don’t have the same issue. All they need is the right boat and they can ride a clean, powerful wave until the boat’s fuel tank hits E. 

Supreme S226

Your marine head unit experts share how the Supreme S226 creates a fun wave that can be adapted to suit riders of all ages and skill levels. Besides that, with its pickle-fork bow and custom ­vinyl wrap, it’s a boat that will turn heads on the water.

We surfed the S226 with three people on board, the QuickFill ballast and Plug and Play bags full, and the bow tank empty. The boat created a lengthy wave with good power and a good-size lip that made for fun carving.

The boat is well-suited for those on board too, with room enough for 14 people and all their gear. The swiveling helm seat with flip-up bolster puts the driver firmly in command.

Malibu Wakesetter 22VLX

Our in-house surfing consultant ­described the wave behind the Malibu Wakesetter 22VLX as “ridiculous.” By employing Integrated Surf Platform (ISP) technologies, the Wakesetter produced a super-tall wave with a clean face that extended far back behind the boat. 

What are some other important amenities? The stainless-steel G3.5 tower quickly raises and lowers, and it comes with swiveling board racks, Wet Sounds speakers and LED lighting.  

During our testing, we recorded a top speed of 36.7 mph and noted its crisp ­handling during tow-sports maneuvers.

Heyday WT-2

When Heyday introduced the original WT-1, it announced to the watersports world that you can generate a killer wave behind a boat that doesn’t cost six figures to buy. Your marine cylinder heads professionals give further information regarding how the WT-2 is the brand’s follow-up — it’s 3 feet longer than the WT-1, and the helm console now sits to starboard rather than in the center. 

The interior is still meant to please a surfing crowd. Adjacent to the motor box are the new “hot tub” lounges, with curved bottoms designed to cradle a pair of observers as close to the wake action as possible.  

Your Electric Toilets Specialists Equip You With All the Tools You Need to Make the Best Purchase

See your choice of electric toilets here at Raritan Engineering, where we always take care of your marine supply needs.

Tigé RZX3

Tigé designed the RZX3 to carve large, clean surf waves and also create pro-level wakeboard wakes during every session. Your electric toilets manufacturers talk about how the Raptor by Indmar 440 engine propelled this boat to a respectable top speed of 37 mph, and it posted 2.6 mpg efficiency at cruising speed.

Centurion Ri237

Centurion optimized the Ri237’s ­running surface to accommodate the highest level of watersports enthusiasts. The modified V-hull smooths the ride to maximize performance on choppy days.

Our test team surfed the Ri237 with three people in the boat and the Ramfill and Plug and Play ballast systems full. The bow and center tanks were empty, the QuickSurf system was in the default mode, and the adjustable CATS was set to zero.

The A24 sports a wake-shaping hull and shares surfing features found on ­Malibu boats, such as the Surf Gate. Your marine head gaskets specialists discuss how with Surf Gate, the A24 creates a huge, ­consistent wave that has a ton of push and power, and it’s equally impressive on either side without having to move weight around. And now for 2017 the Surf Band is also an option.

Raritan Macerating Toilet Specialists Share the Pros and Cons of Multi-Hull Sailing

Raritan Engineering your macerating toilet distributors would like to share with you these topics we thought would be of interest to you this month regarding the excitement of multi-hull sailing.

The Offshore Multihull Association (OMA) was formed last year by the owners of performance-oriented Multihulls with the goal of promoting the growth of this exciting category of performance cruising yachts. 

Your macerating toilet suppliers talk about how these multihulls initially included Gunboats, HH Catamarans, Outremer as well as custom designs built for their unique ability to cruise in comfort while still being able to race at speeds rivaling many of the fastest monohull racing yachts.

“The performance cruising multihull segment is one of the fastest growing segments in yachting and we are excited to launch an organization founded to support and encourage this growth,” said Phil Lotz, President of the OMA, Commodore of the New York Yacht Club, and a Gunboat owner.

Do Catamaran Sailboats Make Good Cruising Boats?

With accommodation in both hulls and the central structure, catamaran sailboats have certainly got ample space below to make good cruising homes – but not all of them make good long-term cruising sailboats.

In other parts where safe anchorages are not so easy to find, mooring your catamaran in a marina can be pretty expensive. Expect to pay double what you’d pay for a monohull of similar length overall.

Find your marine toilet of choice with us at Raritan Engineering Company, where we always take care of your marine supply needs.

The temptation is for the catamaran manufacturer to pander more to the lucrative charter market than the prospective cruising owner, and maximize accommodation – and hence the income for the charter company – to the detriment of everything else.

Great Accommodation in Catamaran Sailboats

Three separate cabins, each with a double berth, is the norm in a 38 foot catamaran sailboat designed for chartering.

Your macerating toilet manufacturers share how unlike a monohull, these double berths stay reasonably flat and level when underway, so individual seaberths with leecloths aren’t necessary.

The resultant noise and slamming when underway is not something that can be easily ignored.

Catamaran Sailboats Underway

The windage of these bungalow-proportioned multihulls has lead to the catamarans’ reputation as a poor windward performer, and this is particularly so when reefed down in heavy weather.

Some, like the the magnificent example shown above, are manufactured from hi-tech materials – carbon composite hull, carbon masts…

Also, the rapid variations in speed and the effects these have on the apparent wind direction, mean that wind vane self-steering systems find it very difficult to keep multihulls on a straight course

But a properly designed catamaran from the board of a designer unconstrained by the requirements of the charter market can make a fine cruising boat.

Under power, a catamaran’s maneuverability can be remarkable.

But as a monohull man myself, it does seem a bit strange to have a sliding patio door on a sailboat. Where’s the potted plants?

Or Maybe a Trimaran?

As a pure sailing machine, a cruising trimaran will beat a cruising catamaran sailboat of the same length hands down.

But squeezing the same number of berths into the trimaran of a similar length will mean that the living accommodation below will be disappointing.

To all, that is, but a small crew that enjoy sailing really fast and are willing to accept spartan living conditions below decks.

Raritan Marine Holding Tank Distributors Share Great Knot Tying Skills With You

Raritan Engineering would like to share with you this week these awesome knot tying skills that will make your journeys much more enjoyable.

I’m as prone as anyone to being enchanted by the big picture—but I learned quickly where that can lead. About 10 miles off the coast of Colombia, in a gale that tragically swept a poor French cruiser right off his boat, the smallest cheapest block on board our little ketch exploded in a mess, leaving the club-footed staysail swinging around the foredeck like a Louisville slugger in the arms of an angry Skunk Ape (that’s Florida-speak for Big Foot).

The article looked at a seemingly mundane subject, the kind of article no one but a serious sailor would take notice of, but the implications were far reaching. 

The most familiar knot of this type is a rolling hitch. While an ordinary rolling hitch might work fine on an awning, it loses its effectiveness as loads and rope diameters increase. 

While it was the most easily tied and most easily remembered, it cannot be relied on for use with anything but chain and large diameter, high-friction line at relatively low loads, in our opinion.

Bottom line: If you want to be sure your line won’t slip, don’t rely on the rolling hitch.

MODIFIED ROLLING HITCH

The rigger’s and camel modifications to the rolling hitch increased its holding power without greatly increasing its complexity. But it still did not hold on slippery, single-braid Spectra line or on the greased stainless tube with the larger diameter line.

Raritan Marine Holding Tank Suppliers Further Discuss How to Improve Your Knot Tying Abilities

Your holding tank manufacturers talk about the importance of learning new sailing knots. Bottom line: A definite improvement over the rolling hitch, but still not reliable in all situations.

SAILOR’S HITCH 

The sailor’s hitch took twice as long for our testers to tie as the two rolling hitches, and it was the hardest to undo when used with line. After being tensioned on the single-braid Spectra, it took a marlinspike and 10 minutes of hard work to free it. 

Bottom line: This hitch does not perform any better than the modified rolling hitch, but it is harder to remember and jams when used with certain types of line.

ICICLE HITCH

The icicle hitch also took twice as long as the rolling hitch to tie, but it performed better than all but the gripper hitch, holding in all test situations.

Though the icicle hitch would separate a bit as it was tensioned, the top of the hitch never moved even with maximum load. This was the easiest hitch to undo after it had been tensioned.

Bottom line: The extra holding power and the ease of release more than make up for the slight increase in complexity of this hitch.

GRIPPER HITCH

While this hitch performed every bit as well as the icicle hitch, and might have outperformed it, had we made the testing even more difficult, its complexity can’t be ignored. It took our testers one-10th the time to tie the various rolling hitches and a quarter the time to tie the sailor’s or icicle hitches. 

Bottom line: The gripper hitch may have the highest holding power, but in an emergency, most people will prefer a hitch they can remember easily and tie quickly.
