Helia Mainsail Headaches

Helia Mainsail Headaches

One complaint we have with the Helia is the mainsail. It has a square top (the trailing edge of the sail doesn’t meet the top of the mast) and it has a large “roach”. The roach of a sail is the amount of the sail which extends aft of a line drawn from the top of the mast to end of the boom.  The combination of the square top and the roach provide extra sail area for the same mast height but complicates the hoisting of the sail.

The main sail is connected to mast with cars which have plastic ball bearings which allow the cars to slide easily on a track attached to the mast. The Helia has a small number of cars (6) which means there is a large distance (more than 10 feet in some cases) between the cars when raising the sail. Because the square top will kick up as it lowered, the top car must be disconnected from the car to fully lower the sail. The problem is this quite a distance off the deck and is too high for Shiera to reach.

After dealing with this headache for awhile after buying the boat, I found a solution with a part called a Gaffe Lock by Karver. This clever device is attached to the top car and allows the sail to detach from mast when lowered and reattach when raised. It does this using a strap on the halyard which pulls into a hook attaching the sail to the car. While it is expensive, it completely solved the problem.

While the large distances between the lower cars was annoying at times, it wasn’t a huge issue until during a passage to the Bahamas when we were assaulted by a large squall with 45 knots winds. We had numerous squalls during the passage and each had lots of rain but little wind.  I had seen this squall approach and it was very dark and threatening. I decided to get the sails down before it hit. I got the jib rolled up but was in the process of lowering the main sail when the squall blasted us. The sail had large billows where the cars were widely spaced and the wind grabbed the bottom billow and ripped the sail from the car. That made a larger billow which then ripped the next car off, and then rest went except the top two. That only lasted a second until the top of sail torn off with a huge crash.  Now we had a huge mess, with the entire main flapping in the breeze and in the water. Shiera and I managed to tame the beast and get it back deck as son Grant struggled to keep the boat into the wind with the autopilot trying to turn the boat back on course (this was his first sail on Gemeaux).

The rest of trip was mostly motor sailing after that, but the sail was repairable when we returned to Fort Lauderdale. Under closer inspection, the car attachment is a stainless steel pin which is screwed into a plastic end cap for the batten. The failure happened with the steel pin tore out the threads from the plastic. The solution was to replace the plastic batten caps with stainless steel caps. That should prevent the failure from happening again. Another solution that other Helia owners have pursued is adding several extra cars. Each car would go between the existing cars thereby decreasing the amount of sail which will billow out. The problem is because of the roach of the sail, the car cannot be directly attached to the sail, it needs to have slack to allow the sail to move away from the mast when lowered. The additional cars also raise the top of the sail making it becomes more difficult to reach the top car from the deck.

Our other complaint is reefing the sail. The Helia has three winches. One is used by the main sheet and the other two are shared with the rest of the lines. The main halyard uses the right most winch which is also used by the starboard jib sheet. The center winch is used by the reefing lines to tighten the clew of the sail, but also used by the port jib sheet. The upshot is that both winches are necessary for reefing but one of them will also hold a jib sheet if the jib is up. While it is possible to switch lines during the reef, the jib sheets have lots of pressure so it is also a good way to lose some fingers. We have typically rolled up the jib prior to reefing to free up the winches and then redeploy the jib after the reef is completed.

Finally the foot of the sail is loose, so it only is attached at the mast to the foot and the clew of the sail is attached with a large strap near the end of the boom. This strap creaks a lot when under pressure making Shiera very unhappy. I haven’t figured a good solution for eliminating the creak.

So while we mostly have made peace with the mainsail, we still have complaints we haven’t solved.

Escape Hatches – Recipe for Disaster

Escape Hatches – Recipe for Disaster

A catamaran unlike a monohull has the possibility of overturning and not coming back rightside up. A monohull can turn over too, but it will always right itself as long as the keel is still attached. A catamaran has two stable positions, right side up and upside down. Because it is possible for the boat to turn in the inverted position with people inside the hull, European boat manufacturers have required the inclusion of escape hatches which can be used to exit an upside down boat. To insure the hatch is as high above the water as possible when the boat is inverted, the hatch is placed at the waterline when the boat is in the rightside up position. All this is well and good, but for most cruising catamarans it is very unlikely the boat will turn over.

The hatch used on the Fountaine Pajot boats is manufactured by Goiot (another French company). It is specifically designed for use as an escape hatch and is rated to be used at the waterline. When we purchased Gemeaux, the marine survey highlighted that escape hatches leaked. It was also noted in the survey that these hatches often leak. I assumed the leak was between the seal and the lens of the hatch. While it is likely that many hatches leak there, I was soon to find out there is a much more serious leak potential.

Goiot Escape hatchAfter about 8 months of owning Gemeaux, we were in the Chesapeake Bay and the port hatch was leaking more than usual. Trying to pin down the leaks was difficult until I pushed slightly on the lens of the hatch and it moved outward. It was then I realized the hatch was not leaking at the seal but was leaking between the lens and frame of the hatch. This would require the hatch to be replaced.

After some work tracking down a US supplier for the hatch and having sticker shock of over $2000 for the hatch, I ordered the hatch and had the boat hauled out of the water to replace it (another $500 to get it out of the water). I carefully inspected the starboard hatch but it seemed fine, no movement between the frame and the lens on that side. Now, I felt prepared to brave the Atlantic on the way to Antigua, no more leaking hatches… or so I thought.

During our crossing all went well until about 500 miles from Antigua when at 8PM, Shiera noticed water on the floor in the starboard bathroom. It was then she saw water spraying across the companionway when Gemeaux hit a wave. The problem was the lens had become detached from the upper part of the frame and now was threatening to exit the boat altogether. If the lens did fall out, Gemeaux would be lost. It wouldn’t sink but it was very unlikely that we could do anything to fix a 3ft square hole at the waterline.

First order of business was to try to get the lens back into the frame. We had a 2-inch glass suction puller for lifting floor panels but couldn’t pull hard enough to get the lens back into the frame. The only viable option was to go in the dingy under the hull and try to knock the panel back in. How scary was that—to be in 6 ft seas at night under the boat? Each wave would drive the dinghy into the bottom of the boat. I was able to time the waves to get a fist on the lens and pound it back in place. Now we needed a more secure fix to finish our sail to Antigua.

In a scene right from Apollo 13, we dumped every adhesive we had on the table. After carefully discussing each choice, we decided on a ribbon of underwater 5-minute epoxy between the frame and the lens. Then we would put 5200 adhesive around the joint. Five minutes is not very long, so we carefully rehearsed our plan and then each of the crew prepared a strip of epoxy for a side of the lens while I went back underneath the boat in the dinghy. We pushed the lens back out, lined the epoxy in the joint and then pressed the lens back into the frame. We could see the epoxy had good coverage in the joint, but just didn’t know if was adhered well. Next, we lathered 5200 adhesive onto the joint between the frame and the lens. We decided to hove-to for the night to give the adhesives time to cure.

Completed repair

As I tried to sleep, I keep worrying that the lens would still pop out of the frame. At 4 AM I came up with an idea to adhere two plastic blocks to the lens with flathead screws drilled through. Then a board was fitted completely across the frame and the screws secured to the board. This effectively leveraged the lens into the frame. We tried several different glues (contact adhesive, silicone, superglue), finally settling on superglue to glue the plastic blocks to the lens. The problem is that acrylic doesn’t take very well to any adhesive, but in our testing, superglue seemed to work the best.

The completed fix held until we reached Antigua where I ordered another lens and had the boat hauled out again. We completed the repair on Thanksgiving Day and celebrated with a BBQed turkey dinner while Gemeaux sat on the hard.

Now I realized the severe safety problem of the hatch. It wasn’t just the hatch that could leak, the entire lens could fall out the boat! The irony is the frame of the hatch is secured with 20 bolts that go through the hull, but the lens is only secured with a thin bead of silicone to frame and silicone does not adhere well to acrylic. I sent a strongly-worded email to both the US Fountaine Pajot dealer and Goiot, the maker of the hatch. I explained that a boat could be lost because of this problem. Unfortunately I didn’t get much of a reply. Goiot said they had no knowledge of failures like this and offered to send new glue to adhere the hatch to the frame. That was not very comforting.

Inside view with fix installed in the upper corners

I decided I could rig a permanent fix for the problem along the lines of a temporary fix. I researched how to attach acrylic to acrylic and found that solvent glue would weld two pieces together. It works by effectively melting the surface of each piece allowing the pieces to join as one. Rather than fit a board across, I used 1/8” aluminum stock in the upper corners across the frame. This still allows the hatch to be fully functional but is impossible for the lens to come out of the frame. The specs on the solvent glue are nearly 10,000 lbs for each 2×2” block. I could lift the entire boat up with that!

In the meantime, our hatch failure was reported on the Cruiser Forum by a boat that had been nearby when it failed. On the forum, I documented the failure, the response from Goiot and my fix. A number of people requested drawings for the fix.

Helia with escape hatch failed

All was quiet for the next 6 months until on the Fountaine Pajot Owners Facebook page a Helia like Gemeaux was reported lost at sea off Africa. The speculation was the boat had hit something in the water and had a large hole punctured in the hull. Looking at photos of the boat, it seemed odd there was no damage to the bow of the boat. Pretty hard to hit something sideways. I tracked down the skipper in Norway and determined the problem was his starboard escape hatch had left the boat at 2 AM in rough seas. He tried many things to stop the inflow of water but ended up being rescued by the Moroccan coast guard and abandoning the boat. This was the exact problem we had, but his lens had completely left the boat.

I posted the information that this was another hatch failure like Gemeaux’s but the hatch had actually left the boat. I included the drawings for the fix and strongly suggested that all owners with the hatch immediately apply a fix to their hatch. Two weeks later another owner off the coast of Brazil had their hatch partially leave the frame. This was now three boats in less than a year that I knew about. I notified the Coast Guard of a potential safety problem (never heard back). Within a month, Fountaine Pajot was notifying owners of the problem and a fix Goiot had developed. I’m not a fan of the fix as it relies on an adhesive bond to acrylic rather than solvent glue to hold the lens in place. I would not bet my life on any adhesive bond with acrylic.

Over the past 6 months, I have been contacted by dozens of owners who want the fix. I have sent a dozen or so people a kit to install and the instructions to many others. Hopefully boats are better prepared now to secure a hatch that is very unlikely to be used for its intended purpose, but could be a disaster like the poor boat off of Africa, or what nearly occurred to Gemeaux in the Atlantic.

The Trouble with Marine Plumbing…. a Shitty Problem

The Trouble with Marine Plumbing…. a Shitty Problem

After Shiera allowed me to have a corner for my own posts, I struggled with what to write about first. Lately I’ve been working with our marine waste disposal system, so perhaps that is a good place to start.

Running a boat is like running your own city, there is power generation, water systems and waste systems. For the waste treatment side of the city, on Gemeaux we have three separate toilet systems which for various reasons are all a little different, however the basics are the same. There is a toilet which uses either fresh water or salt water to flush (more on that choice later) and a holding tank to hold the waste till we are out at sea and can dispose of our waste without fouling the place we are anchored.

Toilet Schematic

The toilet is an interesting piece of engineering. It has a macerator to grind up the TP and poop so it doesn’t clog the tank. The toilet also pumps the result to the top of the holding tank. This prevents a hose or toilet problem from dumping the entire contents of the tank inside the boat.  It generally works well unless something other than TP and poop goes in. We haven’t had that problem yet because we try to educate our guests on the importance of not flushing what should not be flushed.

 

Calcium Cloride Deposits

Two of the toilets on Gemeaux use salt water to flush, the other uses fresh water. Sea water is plentiful and fresh water is hard to come by on the ocean. However, salt water has some downsides. One is it contains plankton and other small critters which die when they are in the system for more than a couple of days. This creates an unpleasant sulphur smell in the toilet and the sea water inlets into the toilet. The second problem is the reaction of salt water and urine. The ammonia in urine reacts with the calcium in sea water to create deposits of calcium chloride which is hard like rock and coats the inside of hoses, pipes and tanks. It can also break off and clog the outlet of the tank.

 

For the first year we owned Gemeaux we struggled with one of the port side heads (on the guest side of the boat) always getting the outlet of the tank clogged. To clear the clog was a very messy business of using the dinghy pump to force air into the holding tank outlet to push the clog back into the tank and allowing it to empty. It was a very unpleasant task. After this, we had all the tanks removed and replaced all the hoses. When the tanks were out we cleaned them to remove all of the deposits. We also switched the offending tank to fresh water. Those changes seemed to solve the problem in that tank.

To deal with the deposits of calcium chloride in the tank we tried vinegar which is a mild acid. That didn’t seem to help, so we switched to hydrochloric acid (muriac acid in the store) which we dilute and then pump into the plumbing system every couple of months. When left for several hours it seems to clean up the deposits pretty well.

Cleaning the toilet holding tank

After Gemeaux’s summer vacation out of the water, our clogging issue moved to the starboard side which is the toilet we use. First attempt to fix the problem was to remove the tank and inspect. Found lots of calcium chloride deposits in the tank with large sheets which had detached from the tank walls. Seems like more often use of acid is required. After a couple of hours of labor by David Thomas and me, including the use of some rebar, most of the deposits were removed and the tank returned to service. Well, more blockages occurred. Used a endoscope my surgeon brother gifted me to inspect the problem. Seemed like the blockage was above the valve to open and close the tank. Took the tank out again and inspected the outlet hoses and valves. All looked good. Applied an overnight acid soak and now the problem seems cured… till the next time.

Allen’s Boat Corner

Allen’s Boat Corner

Shiera has been doing a great job on documenting our adventures, but I thought I could add some interest by documenting what we are learning about Gemeaux. While I have owned all number of boats in the last 50 years, beach catamarans, ski boats, houseboats, river running rafts,  this boat has lots of new things to learn and challenges to solve. Perhaps things that I have learned could help others, perhaps others could help me learn more as well! In the last two years I have tackled steering/autopilot issues, toilet issues, air conditioning, windless problems, sail problems, and on and on; the list seems endless.

Gemeaux we bought after she had two owners. The first had done a great job outfitting the boat and eventually sailing it from Europe to St Martin. The second owner was very short lived, and apparently only sailed the boat a couple of times. After purchasing the Gemeaux, we made a list of improvements that we wanted to add, mostly for creature comforts. This included a generator, air conditioning, washer/dryer and chartplotter at the helm. We also replaced the steering system. This batch of changes we had done at Just Catamarans in Florida.With that intro, I’ll try to plunge into things I would like to share about our boat.

Meet Allen

Meet Allen

So Allen wants his own blog. This is a man who just last week accepted my daughter’s Facebook friend request from 8 years ago, who teases me about having three Instagram accounts, and snubs how Facebook cat videos are constant entertainment for me. He has never played Words with Friends or posted a selfie. He uses three phones and has an electronic portfolio that would be the envy of any super yacht. He has dozens and dozens of phone apps–mostly providing a different view of weather and the New York Times to keep him connected to civilization.  But, he remains steadfast in his belief that social media is not for him. Until now.

In the quest to share his innovative solution to leaking escape hatches (see Destination to Antigua)Allen has created an impressive network of what I like to call Hatchlings. These are people across the planet who, through Allen’s outreach and brilliant problem-solving abilities, understand why certain emergency escape hatches on catamarans fail and want to prevent this life-threatening situation from happening on their own boats. They have requested information, shared stories, asked questions, and received Allen’s kit–2 custom-made aluminum bars, 4 bolts, 1 tube of specific adhesive, and a partridge in a pear tree. They have created Allen’s entrée into social media and without question, justified his request to continue sharing through his own blog.

So if you’re one of our readers who wants to understand this whole hatch problem, dissect the benefits of ac versus dc power, or curious about what a fo’c’sle is, welcome! You’ll find Allen’s posts under his very own Allen’s Fo’c’sle. Enjoy!
