Your Marine Head Specialists Discuss How to Loosen Up Those Tight Nuts and Bolts 

Raritan Engineering your marine head distributors would love to share with you this week these great pointers on how to unstick pesky bolts and nuts.

My friend Nick and I had a discussion the other day about which bolts were tougher to break free: shaft coupling bolts or the lug nuts on an old trailer.

The muscles, in this instance, were those of Dustin Rahl, owner of a very busy mobile trailer service in Sarasota, Fla., Trailers 2 Go. The axle on the trailer for our Catalina 22 test boat Jelly (aka Our Lady of Perpetual Despair), had cracked at the weld, so that its left wheel splayed outward at a 20-degree angle.

But what happens if the PB isn’t enough? Carefully applied heat from a butane, MAPP-gas, or propane torch is usually the next step. After that, it’s time to break out the specialty tools.

Like a chef with a favorite set of sauce recipes, a good mechanic needs a tried-and-proven list of tricks to help coax rusted fasteners into submission. Their tools range from penetrants and ingenuity to pure brute force.

When good nuts go bad, its time to call in the bone crushers.

One unusual but effective fastener-freeing technique involves massive thermal change that causes an abrupt material expansion or contraction.

Your Marine Head Suppliers Are Happy to Supply You With These Amazing Tips

Sometimes, all a bolt needs is a few good wacks to loosen the bond, but be careful! You don’t want to damage the threads. Your marine head  professionals continue discussing that if you can only approach from the threaded end of a bolt, you can put another nut on the bolt and tap that — not too hard.

The rusting process also degrades bolt head shape. A last ditch effort may require a pair of Vise-Grips or sockets designed to grab deformed bolt heads. For stuck, slotted-head bolts, an impact screwdriver can be a real lifesaver.

I’d be interested in hearing of other tried-and-true methods for un-seizing the seized.

If you work on a boat you already know nuts and bolts freeze with frustrating frequency. Sometimes it’s a carbon steel bolt corroded solid on a cylinder head. Other times it’s a stainless steel bolt frozen solid in an aluminum lower unit.

Begin with fire. An oxy-acetylene torch works best. The downside, if you don’t already own one, they are expensive to rent and complex to fire up. And because of the inherent danger of working with an open flame near an inboard gasoline engine tucked into an enclosed space, first run the bilge blower for several minutes to ventilate the area.

Know that sometimes the flame blossoming from the common propane torch may hold enough BTUs to get the job done. Either way, oxy or propane, heat the bolt. No need to go red-hot, but hot enough so droplets of water flicked onto the bolt sizzle off into a vapor.

An alternative to fire is ice. Some mechanics claim dry ice will shrink a bolt enough to break corrosion’s hold. Though most of us choose a torch because it’s quicker if not more dramatic. Besides dry ice, there is another cool option. It is an aerosol spray that freezes metal ice cold, more particularly a blast of freeze spray, an aerosol that super chills metal parts to minus 72 degrees Fahrenheit.

Sometimes the corners of bolt head round off making it impossible for a wrench or socket to grasp hold. Calmly reach for a center punch and a ball peen hammer.

Never use force. Just get a bigger hammer. When you are willing to sacrifice the bolt, position the wedge tip of a cold chisel against the corner of the bolt head or nut and bang away with repetitive strikes of a ball peen hammer.

Finally, assembling fasteners with anti-seize compound in the first place is a good way to keep fasteners from corroding in the first place. For example, on new outboards I remove all the bolts in the lower unit, one at a time, coat them with anti-seize and then replace.

Boat Head News Dept Says: Stonehill College student, Linsey Malia, killed in Copenhagen boating crash

A student attending Stonehill College in Massachusetts is one of two women who died when a jet ski crashed into a boat Saturday in Copenhagen.

Stonehill College in Easton, Massachusetts confirmed Linsey Malia, class of 2018, died in the boating crash.

The college released a statement Sunday afternoon that reads:

“The Stonehill community is deeply saddened by the loss of Linsey Malia ’18. As a peer mentor, a teaching assistant, a member of the Moreau Honors Program, a work study student within Athletics, and a volunteer with multiple campus partners. Linsey was a model student and member of the College community. We ask that the media give her family and friends space as they take time to process this tragedy and grieve.”

Jim Malia, Linsey’s uncle, who lives in Bellingham, posted on Facebook that he received a call from the US Embassy in Denmark stating she was killed in the boating accident.

“We are all heartbroken that such a beautiful life was cut short at age 21,” he wrote. “Rest In Peace Linsey. We all love you.”

Malia was one of four students who played Ace the Skyhawk, the college’s mascot, at various athletic events. She is listed as a psychology major and sociology minor

The two American students were part of DIS – Study Abroad, according to a statement from DIS posted on Facebook. The second American student who died has been identified as Leah Bell, a Louisiana native and student at California’s Pomona College.

A Facebook post by the Christ Episcopal Church in Louisiana identified Bell as the victim. She is from Covington, Louisiana.

“It is with overwhelming sadness that we write to inform you that the oldest daughter of Jeff and Liz Bell, Leah Bell, was killed in a tragic boating accident in Copenhagen yesterday during her study abroad,” the post states. “Jeff and Liz are on their way to Copenhagen and their daughter Rebecca is here with friends. Every loss is painful – and if we are human, we have or will experience such loss. But the loss of a child is particularly devastating. We ask that you please hold the Bell family in your prayers and close to your heart during this difficult time.”

DIS said seven students were boating on a personal excursion in the Copenhagen Harbor when a “high-speed jet ski” hit the boat.

“Tragically, two DIS students were killed as a result of the accident,” the statement from DIS says. “This incident is incredibly difficult. DIS is a strong community and the ties to these students involved in the accident are broad and deep. DIS is focused on individual support and counselors are available to all students.”

The five other students were released from an area hospital.

The Copenhagen Post reports the students were celebrating the end of the spring semester and authorities in Denmark have arrested nine people in connection with the crash.

Riding jet skis in the harbor is illegal, the Copenhagen Post reports. The incident remains under investigation. Some people riding the jet skis fled the scene, according to the newspaper.

Your Boat Head Specialists Share Great Tips on Keeping Your Display Panels In Great Shape

Raritan Engineering your boat head suppliers would like to share with you these topics we thought would be of interest to you this month regarding the best way to maintain your display panels.

Your boat head distributors continues to discuss how touchscreen displays make marine electronics easier and faster to use than ever. Once you use a touchscreen, you’ll never want to go back to the old-fashioned push-button mode of operation. Think in terms of today’s touchscreen smartphones — would you ever want to go back to a flip phone?


If your electronics displays are bracket-mounted, remove and stow them indoors between trips. Your marine parts outlet manufacturers continue sharing how this will minimize weather exposure and thwart would-be thieves. Transport your equipment securely between the boat and storage location.


You can’t easily remove flush- or surface-mounted displays to stow them off the boat, but you can use a sun cover on them. The company that makes your display will offer a sun cover in the appropriate size for each model.


Virtually all marine electronics displays are built to an industry water-ingress standard such as IPX6 or IPX7. Yet it is still a good idea to protect both the back and front of the display from spray whenever possible.

Your marine parts near me specialists give further tips regarding how caring for a boat is a constant process. The amount of wear that normal water conditions can cause can strip paints and varnishes, and animals can fly overhead or climb on board and leave messes.

Choosing Soaps for Marine Use

Soap and water seem like a natural pairing. But soaps that are not rated for marine use can cause a number of harmful problems to the water around you. Phosphates in soaps cause algae growth that can pull oxygen out of the water and cause fish kills.

Your Boat Head Distributors Talk About Proper Cleaning Methods

Don’t forget that you can find marine supplies here at Raritan Engineering. We always take care of your marine supply needs.

Boat Surfaces and Their Care

  • Fiberglass: Your boat head experts share how fiberglass is one of the most common and easy to clean surfaces on a boat. Your marine parts depot suppliers continue discussion of how much like the exterior of a car, a good paint job, regular washing, and periodic coats of wax are all that is needed on a normal basis to keep the exterior looking good.
  • Aluminum: Aluminum needs little done to continue to look good. A regular wash is most of what is needed. The real risk with aluminum is wear due to galvanic corrosion (the kind of corrosion that boat zincs are placed to protect).
  • Other Metals: Brass, chrome, stainless steel, and other metals can be cared for on a boat if you follow a few simple rules:
    • Consider the marine habitat when using corrosive polishes to refinish. If you want to use something very toxic on something like a propeller, it would be better to remove it from the boat and relocate it to a place where the substance will not end up in the water.
    • Do not mix metals, and ensure that the more active your metal, the better protected it is (and stays).
    • Protect from galvanic corrosion with zincs. Ask a marine mechanic for help if you do not know how to place these yourself.
  • Glass: Glass is one of the most likely surfaces to show spray after you take a ride on your boat, but one of the easiest to clean. Marine rated glass cleaner works well, and many a sailor swears by saltwater and newspaper for a high-polish shine.
  • Isenglass: Though this thin glassy substance serves the same purpose as a glass window, cleaning it with anything ammonia based will ruin it forever. Instead, water and mild dish soap or boat soap is enough to keep your canvas windows looking shiny and new, and to protect your canvas from premature wear due to chemicals.

Boats are one of the best ways to spend a spontaneous weekend away on a romantic cruise or fun trip with the kids. However, unless surfaces are properly maintained, a carefree jaunt can quickly become a long work weekend.

Your Macerating Toilet Specialists Share the Steps You Need to Take Before Making the Purchase

Raritan Engineering your macerating toilet professionals would like to share with you these topics we thought would be of interest to you this month regarding the benefits of buying used marine equipment.

Are They Right For You?

Your macerating toilet analysts suggest that you look for corrosion. There are steps you can take on your own when you are looking at used marine electronics. Corrosion is a major issue in the marine environment. Anything and everything left on a boat will corrode soon or later if left unprotected. When you inspect a used piece of boat electronics, look for signs of corrosion. 

Display OK?

How can you tell if a sounder or chart-plotter display has seen better days? If there is a line through the screen that is an indication that a full row of pixels is missing, not a good sign. Screens can de-laminate, too, meaning their anti-glare material is starting to wear off. 

What About Installation

Think ahead about the unit installation—where will you mount it? Is the spot big enough? Will the access to controls be right? Where will the cables to the unit run? Unless you are replacing a machine with the exact same unit, there will be installation modifications that will need to be made. 

What About the Warranty?

One big downside when purchasing used gear: Your macerating toilet analysts feel that used or refurbished marine electronics are usually not backed by a manufacturer warranty, though if you purchase through a dealer you may get a short term warranty.

Go to Raritan Engineering and find your marine toilet of choice. You can always trust us to take care of your marine supply needs.

Q. Is buying used equipment a good way to save on electronics?

A. Used electronics can save money but can also be risky. First, ask yourself some questions. Will the equipment meet your needs and expectations for now and in the future? Is the equipment expandable? 

Tips for Buying Used Electronics

1. If you are planning to buy used electronics, it is essential that you have a right of return for a full refund if you are unsatisfied for any reason. You should ask for at least a 30-day right of return.

2. Don’t overlook the cost of shipping. Depending on the size and weight of the item(s), this can be significant. Should you want to return it, the shipping costs can double.

3. If you are not familiar with the model you are considering, you may want to check online for general information and owner comments.

4. Also, check to see what similar models are being offered for sale to confirm you pay a fair price.

Buying a Used Boat With Existing Electronics

1. If you are buying a used boat with existing electronics, confirm operation of the electronics with a demonstration including a test underway to check the autopilot, depth/fish finder, boat speed indicator or radar. 

2. Consider hiring the services of a local marine electronics dealer or technician to survey the equipment to determine its operation and true value.

3. When negotiating a price, it is best to assume that you will need to replace and upgrade older electronics. This will help ensure you pay a fair price for the boat itself. 

Advantages of Buying New

1. Before you buy, check competitive pricing on new electronics. Manufacturers frequently offer specials. Boat shows are a good source of bargains as well.

2. Check your local electronics dealer for markdowns, older inventory, discontinued models and showroom demos, as well as trade-ins. 

3. A factory-certified technical installation dealer for certain brands might be able to certify and extend your equipment warranty an extra year or more.

Your Electric Toilets Experts Share How to Get You Through Those Hopeless Situations 

Raritan Engineering your electric toilets professionals would like to share with you these topics we thought would be of interest to you this month regarding how to survive a mast breaking on you.

Your electric toilets analysts say that after days of poor wind, the forecast finally calls for winds of above ten knots, with things getting pretty crazy later in the evening. I decide that it is time to skip out early on work and head down to the club. I ask my sailing buddy (and co-2nd vice) Chris Lalau Keraly if he’s up for a sail, to which he replies “Screw science, I’ll be there at 3:30!” 

Your marine supplies Tampa specialists understand that the wind is coming from the north, so as soon as we get away from the dock, we hoist the gennaker and take off towards the toilet basin on a broad reach. Before getting too close, we jibe and start making a beeline for the southwest corner of the senior dinghy area. The windspeed seems to be varying between 10 and 15 knots, pretty patchy at times,  but we get in a good enough run with me at the tiller.

Near the southern boundary of the senior area, we douse the kite and start beating back up towards the Berkeley fishing pier. I let our novice crew member take the helm,  and he does an admirable job of harnessing wind and wave to get us back upwind. 

Fortunately, nobody is hurt by the falling mast. We quickly drop the anchor to assess the situation: we are about a mile to the west of the Ashby Shoal, the boat is not sailing anywhere in its present state, and we’ve got about two hours until sunset. As Chris starts detaching the sails from our mast with the help of our third crew, I try to raise the Cal Sailing dayleader on the radio.  

Your Electric Toilets Specialists Discuss How to Not to Lose the Big Race

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

Your electric toilets experts know that breaking masts is an expensive and dangerous proposition — what could have been done differently to avoid this accident? I believe the most important lesson to be learned from this experience is that equipment cannot be checked often enough. 

As summer approaches, so too come the big winds, and the potential for more broken masts. Your marine supplies Seattle professionals feel that while equipment failure can happen to anyone, we all can work to minimize the risks of it happening: thoroughly check  equipment, and sail only in conditions that you, the boat, and the crew can handle. Here’s hoping that we keep broken masts to a minimum this season.

Broken mast: How do you get home in one piece without tearing your sail to shreds you ask? Your marine supplies New Orleans analysts know that it’s time to do the on-water-derig; a seemingly complicated maneuver but once you’ve got the basics down it’s very straightforward and an important safety procedure to remember. Firstly, sit on the middle of your board with one leg over each side in the water for balance, then detach the sail from the board.

Your Marine Hose Professionals Share-Improve Your Deep Fishing Skills Even When the Fish Aren’t Biting 

Raritan Engineering your marine hose analysts would like to share with you these topics we thought would be of interest to you this month regarding deep water fishing tips.

Your marine hose experts know that bluewater anglers are beginning to fish deep to lure billfish and tuna when the surface bite slows.

Savvy captains extend their spreads ­vertically, from the bottom up, and experiment with baits for multiple species through the entire water column. Others are looking from the top down, just a bit below the waves to find billfish and tunas when the surface bite slows. 

Going Deep, But Not Too Deep

Success at catching swordfish from deep water during daylight hours has encouraged enterprising captains to find new tuna and marlin fisheries in 1,200-plus feet deep of water.

“When you hook up on the buoy line, reel in the bottom rod before you do anything else,” Green says. If the bottom line hooks up first, he starts reeling it in immediately and uses a Hooker detachable electric motor on his 50-wide to retrieve the buoy line unattended. 

Buoy Rig and Bottom Rod

Capt. Lee Green starts his buoy rig with 1) 500 yards of 130-pound Spectra braid on the reel. 2) From there, he attaches 3 feet of 250-pound mono to a Bimini twist in the braid, and then a hollow-core Spectra loop spliced to the mono. 

Capt. Triston Hunt uses the same system as Green in the same waters, rigged on an 80 with all 80-pound braid, but he forgoes the buoy. 

We have many marine hose choices at here at Raritan Engineering, where we take care of all your marine product needs.

A soda bottle and rubber band are all that’s necessary to keep a bait suspended off the bottom. The real trick is getting the bait deep in the first place.

Not Quite At The Surface

If porpoises are hot after a school of baitfish, chances are tuna or billfish might be below them, attacking and driving the baits to the surface.

Sawley often finds billfish lurking behind the tuna and porpoise melee too. “Any time we are live-baiting in Panama, I put one live tuna, about 4 pounds, on top and another one on a downrigger ball. 

Planer From Cleat

Capt. George Sawley attaches 1) a short piece of 5/16 nylon rope to his transom cleat. From there, a heavy swivel connects to 2) 100 feet of aircraft cable ending in a snap swivel. 3) Another 4 feet of aircraft cable continues to a large planer. 

In-line planers have been around for decades, but a removable planer rig is catching on throughout the East Coast. laner.

Removable Planer Rig & Spooning

Capt. Chris Gornell connects his rod’s braid to 1) a few feet of 200-pound mono via a wind-on swivel. 2) Interlocking crimped loops connect that mono to 3) another piece of mono, just a bit shorter than a No. 12 planer when it’s tripped, and then comes 4) another set of interlocking crimped loops.

7) Double snap swivels attach the planer to the loops, and once it’s removed, the mono, swivels and crimps all wind through oversize rod guides.

Dredging Up Surface Bites

Dredges can attract fish to surface baits. When marking fish on the bottom machine, make tight circles and drop the dredge deep to excite sluggish fish. 

Off Virginia Beach, Capt. Randy Butler uses live tinker mackerel (Atlantic chub mackerel) to bring white marlin up from below 300 feet. 

How Long Do You Go?

Marlin can spend a quarter of their day feeding at least 150 feet below the surface, searching out optimal baitfish and oxygen levels during the day.

“With situation like that, it’s easy to see to fish a midrange. When it isn’t that clear, that’s when things get difficult. No one wants to get skunked, especially 80 miles offshore,” Boyle continues.

Your Boat Head Experts Give Young Ones The Extra Confidence Boost They Need

Raritan Engineering your boat head professionals would like to share with you these topics we thought would be of interest to you this month regarding how to help you children expand their sailing horizons.

Your boat head analysts appreciate that incremental steps of empowerment builds the kind of confidence and skill that can lead a young child to successfully tackle all sorts of adventurous escapades as they grow older. 

Our cooking utensils were old-fashioned Florence oil stoves, a sauce pan and a frying pan. Your marine products for sale professionals feel that our food was Hecker’s oatmeal, eggs, potatoes, onions, pilot biscuit, bacon and canned goods. 

The cabins were so small that it wasn’t possible to sit up quite straight and of course everything got damp and moldy and there was a permanent smell of a mixture of mustiness and kerosene. 

Our first cruise was around Cape Ann to York Harbor and back. The run from York to Cape Ann is about 30 miles, and across Ipswich Bay the straight course carries you seven miles off shore. 

We anchored in Gloucester about 10 o’clock, and when we waked about five the next morning, there was Lester Monks, who was Guy’s crew, grinning down the hatch at us. 

Guy told us that while sitting steering in the dark, he kept noticing a red light that seemed a long way off. All of a sudden he was stopped by a coasting schooner looming up out of the darkness and passing very close. 

We know that learning to sail together binds you as a family. Because we’ve done it. Your marine supplies near me analysts suggest that you get to work as a team, older kids become engaged in learning something practical that also carries clear responsibilities, and you are encouraged (some might say forced?) to spend time together as a family in a small space.

To be honest, I’m an unlikely sailor. I can only tell which way the wind is blowing by a complicated system of hair flicking, I couldn’t hook a fish out of an ocean if my life depended on it, if there’s a rock anywhere I am magnetically attracted to it, and if I see a coffee shop then that’s my sailing done for the day. 

Your Boat Head Specialists Explain All the Skills You Need to Be Successful

Remember that we have all the answers to your marine product questions and that you can find marine supplies here at Raritan Engineering. 

Your boat head specialists know that there’s lots to learn with different skills for everyone to master – chart reading, navigation, sail work, steering, radio operation, weather forecasting, rope work, kayaking, anchoring, snorkeling, even diving! 

And while you should definitely invest in a recognized course with qualified instructors, you don’t necessarily need to shell out to do it in the Caribbean. Your marine supplies Jacksonville FL experts understand that the Royal Yachting Association is the UK governing body for all things boating. 

There are many ways you can learn. When we first took a boat out on our own, in New Zealand, we didn’t do a formal course. We found the sailing equivalent of a man with a van, and crammed ourselves into the tiny cabin with maps and charts. He sent us off on his own when he felt we had learned enough from him.

Here’s our suggestions for some great places you can learn to sail as a family, based on our own personal research and experience and what others have told us of their sailing adventures.

via Family Sailing: 4 Great Places to Learn

Products sold for marine holding tank treatment and odor control are one of following types:

  1. Chemical based products has one of the most common actives ingredient as formaldehyde or glutaraldehyde or quaternary ammonium compounds. Some of them claim to be biodegradable but they are not environmentally friendly.
  1. Enzyme based product uses specific enzyme. Because enzyme are typically specifics to a particular a substrate, they do not breakdown all matters in sewage and requires frequent use to keep supplying catalyst.
  1. Nitrate type add nitrates to tank which help release oxygen from organic matters to keep decomposition process aerobic. Requires frequent use to keep supplying nitrate.
  1. Bio-system are based on spore or bacteria that multiply themselves once organic matter is available as food. Unlike enzyme they can adopt to varying matters like sewage or toilet paper or oils and can survive some adverse condition of chemical or temperature. K.O.( Kill Odors) and C.P. (Clean Potties) by Raritan  are bio systems.

What is Spore?

A cell made by some bacteria that is like a seed and can produce a new bacteria when organic food is available. It a dormant bacteria that comes alive when exposed to organic matter and can multiply itself.

What is Enzyme?

An enzyme is a protein that acts as a catalyst. The enzyme is responsible for accelerating the rate of a reaction in which various substrates are converted to products through the formation of an enzyme-substrate complex. Enzyme are not bacteria and cannot multiply itself.

How K.O. and C.P. works:

 K.O. (Kill Odors) and C.P.( Clean Potties)  contains multiple spore blend concentrate specifically formulated for use in a broad range of applications including the maintenance of sewage lines, improving waste degradation in holding tank and odor control.

In their natural environment, bacteria produce hundreds of enzymes in response to the organics present in their environment. They produce extracellular enzymes that break down proteins, starches, fats, oils, greases and toilet tissue into smaller particles outside the bacterial cell.

The bacteria then transport the smaller particles across their cell membrane for use as an energy source and for building of new cellular components. The bacteria detect the organics present as potential food and produce specific enzymes to breakdown these organics – it is a very efficient system.

Sewage discharge lines from toilet and holding tank systems are nutrient rich systems for bacteria. Although many bacteria can utilize these organics as food sources, it is the bacteria with the most rapid production of these key enzymes that provide the most dramatic effects.

The microbial consortium in our product produces key extracellular enzymes including amylase, cellulase, lipase and protease for fast and effective degradation of organics.

Marine Holding Tank Odor Tech Tips:

In order for K.O. to be effective we must remember these three important factors:

  • DON’T KILL IT! As discussed, KO is a live bacteria and we must not destroy it. Using chemical bowl cleaners, pine oil, alcohol or bleach based products will terminate the bacteria we are trying to grow and render KO ineffective.  When it comes time to clean the head, stick to our Cleans Potties product.  It has no chemical properties, smells great is safe for any head and holding tank system.
  • MORE OXYGEN! For KO to be most effective, it needs air.  Single, undersized vents restrict the amount of oxygen to the tank and limits its ability to thrive.  Vent sizes should be at least ¾” and if possible, add a second vent to help with cross ventilation.  If vent filters are installed, we suggest they be removed.  While this may sound counter intuitive to eliminating odor, the more oxygen the better.
  • FEED IT! Like all living things, it needs food to grow.  Holding tanks are there for a reason, don’t be afraid to use them!

Getting started:

The best practice when using K.O. for the first time is to thoroughly clean and rinse the holding tank after pump out.  It is important to ensure any residual chemical is removed from the start.  Next, flush 4 ounces per 25 gallon of holding tank capacity directly into the head.  Keep in mind the object is to get the bacterial process started in the holding tank.  If the first flush doesn’t make it to the holding tank, flush the head until it does.  That’s it!  Repeat after each pump out and enjoy your odor free system!


Do not store in direct sunlight or in your car.

Do not store below 40 degrees F.

While our K.O. product does not expire, it can become less effective over time.  We suggest you keep your supply to under one year.

DO NOT use in combination with any other products other than our Cleans Potties Product.

Our Cleans Potties product is the only recommended bowl cleaner for Raritan heads and Waste Treatment systems.

These are the means capable of undergoing self-contained and self-sustained exothermic chemical reactions for the production of heat, light, gas, smoke and/or sound.

Non-Pyrotechnic Signaling

As opposed to pyrotechnic signaling, these are the methods used without the necessity of an exothermic reaction to attract attention at the time of distress. Following are the means of non pyrotechnic signaling used onboard ships:

1. Orange Signal Flag: Listed under the Annex IV of the IMO International Regulations For Preventing Collisions At Sea, this signal consists of a square flag which has above or below it a ball or any other object that resembles a ball.

2. Marker Dyes: In accordance with the Annex IV as mentioned above, a dye marker may be used for the purposes of distress signaling.

3. SOS: The universally known SOS as per the Morse Code which basically is the most widely known way to communicate distress.

4. Radio Signals: As part of the GMDSS, radio signaling is a method of communicating distress at sea. A distress alert may be sent by the Digital Selective Calling methods transmitted on the VHF channel 70 or the following MF/HF frequencies:

  • 5 kHZ
  • 5 kHZ
  • 5 kHZ
  • 6312 kHZ
  • 12577 kHZ
  • 5 kHZ

5. Mirrors: Better known as a Heliograph, a mirror might be used while onboard and mostly on a survival craft to reflect the sunshine towards the entity that one needs to attract the attention of.

6. Continuous sounding on the fog signaling apparatus onboard is a way to communicate distress

7. When the word “Mayday” is communicated verbally via radiotelephony, it indicates distress

8. As per the International Code of Signals (INTERCO), the flag NC indicates distress

9. Slowly and repeatedly raising and lowering arms outstretched to each side indicates distress

10. A ship to shore distress alert which is transmitted by the ship’s satellite communication system (INMARSAT) or any other mobile satellite service also termed as the ship earth station.

11. Signals transmitted by the Emergency Position Indicating Radio Beacon (EPIRB) indicate distress

12. Signals transmitted by the Search and Rescue Radar Transponder (SART) also indicate distress

The INTERCO and the IAMSAR Vol III must be read thoroughly to familiarize oneself with myriad means to communicate and assist in times of distress.

Pyrotechnic signals are visual and attract immediate attention to the casualty of the distressed vessel or persons. However, with the advancement of technology, quicker and better means of communicating distress have come about and the ship’s crew must be thorough with each and everyone of them.
