A54 Main Sail furling foil weak point

Arno Luijten
 

Dear Forum,

This week I finished a repair that may interest a few of you. From what I know quite a few A54s have had a repair to the foil inside the main mast.
Our build number 121 has had a repair on the foil at some point. Unknown who made the repair.

As we have bought a new mainsail I decided to do a close inspection of the furling system while there is no mainsail present. I noticed the sail-groove between the lower short piece of foil was not exactly in line with the large part that goes up the mast. Upon closer inspection and disassembly I found a few things.
Inside the foil at the point where the two pieces meet is a piece of half-round aluminum rod that connects the two pieces. It is screwed with 8 M4 screws to the inside-back of the foil.
I noticed the rod was actually twisted at the point where two foil-pieces meet. Clearly a result of too much torsion force exhibited to the rod. As the rod occupies less then 50% of the diameter surface of the foil this was not a big surprise. It also explained the misalignment of the the sail-groove. The picture below shows the twist in the rod if you look carefully.



So I had the local workshop straighten out the rod again using heat and other clever stuff. Next I drilled new holes in the reinforcement rod, this time for M5 screws to get a stronger connection between the foil and the rod. I also had the workshop prepare a collar for me that slides exactly over the foil.




The collar has a slit to allow access to the sail-groove in the foil. It screws sideways into the reinforcement rod using M5 screws. I also added a few M4 screws into the front half of the foil. In hindsight I should have used rivets for those front screws as the foil has very little "meat" in the wall to tap a thread.

This is the result





This will give much more support to the torsion forces exhibited by the motor and I expect the rod no longer to get deformed because of torsion forces.

The original repair was actually done quite sloppy. The screws in the rod were only M4, not drilled perpendicular to the surface and clearly not strong enough as some of them ripped out the threads. Other were seized as no Duralac/Tef-gel was used.
What also went wrong during the original repair is that the reinforcement part that sits inside the base of the foil (a short piece of the same rod as earlier described) where it is connected to the drive system somehow managed to slide upwards into the foil-tube when they were drilling the hole for the bolt that connects the drive to the foil. The result was that the reinforcement part was not doing anything. Because of this the bolt-hole in the foil turned into an oval giving a lot of play in the connection. So I re-drilled/reassembled it to look like this


Now the bolt goes through the reinforcement and I also added a screw to fix the reinforcement part to the back of the foil-tube to prevent it from moving inside the foil. This makes the connection much stronger obviously.

Finally I also modified the outhaul-car to get some better attachment points for the drive system



I hope this is of some help to other Amel owners that may have similar problems.

Eric,
Your solution of a short removable bowsprit is sound and well proven, no question about that, and I much respect it. Mine is only a matter of a personal preference, and I took a little bit of a chance trying something of which, at least in my area, there was no .previous reference. Fortunately everything went well and I’ll put some photos on my next post

From about 14:40 to 17:40 this video shows the replacement of the front windows.  ALL OF THEM (4) for a total of $1200.  And, after 2 years, I am still happy with the final product.

US$1400 for materials?   That seems rather.... insane.

A 36"x72" sheet of 3/8 (10mm) acrylic sheet costs less than US$300 retail in the US market.  It always pays to shop around...

I think if the sail is luffing there is a risk that the line get stucked, so i prefere this setup with more guidance.

I tried to replace my forward and side acrylic windows and was quoted $1400.00 US for the material and $600.00 to install them
I checked St Thomas and the 10mm acrylic price was $280.00 US  and $200.00 US to cut and drill them. I removed the old windows with my Fein Tool scraper blade.
They would have installed them for $240.00 US more.

Hi Paolo,
I had a removable forestay made. It sits about 2 1/2 feet forward of the bow. It is only 3 feet long in total. I has a Harken swivel block on the end and mounts in about a minute . I store it in the port cockpit locker.

Re: Windscreen Replacement

While $200 is definitely worth it and cutting and drilling acrylic sheet, perspex or plexiglas is a bit nerve wracking, it is quite easy to do yourself without special tools.  The secret is to go slow and use fine toothed blades with tape on the acrylic where you will run your saw so that you don’t scratch it.  

I had a $1200 4’x6’ plexiglass bubble canopy made for my homebuilt airplane and it was shipped to me as a WAY oversized bubble that I had to cut at least 6” off of each edge and drill about 100 holes in it so that I could rivet it to the frame.  I was completely panicked about cutting it myself as I had visions of it cracking or me screwing up and slipping and me cutting it on a wrong angle.  It took me about 2 weeks to work up the courage to cut it.  In the end, I just put down some wide masking tape (painter’s tape) to rest the jigsaw on (and drew my cutting line on it), set up a guide fence (a small wooden baton that I clamped at each end the right distance away from my line), and let her rip with my hand electric jigsaw with a fine toothed metal blade on it.  I went nice and slow and kept the jigsaw up tight against my ‘fence”.  The lines that came out looked like they were cut with a laser and a touch of 600 grit sandpaper rounded over the edges to make nice clean edges for the exposed edges.  

I also had a few parts with radical compound curves that I had to cut with a grinder disk and those were easy as well although getting a perfectly straight line was a bit more challenging as I had to use the grinder free hand so I went a bit wide of the line and then “sanded” back to the line with wet/dry sandpaper (started with 220 grit and went to 600 as I got to the line).  

Same for drilling…. Don’t run your drill at max speed, start with a small bit dead centre of where you want it and then go to your proper size next.  Don’t try to force the bit through… just let the bit drag the drill through slowly.  I put a backing block behind the plexiglass that I drilled into but later I found this wasn’t necessary as long as I went slowly.   I went really slowly at first but by about the 20th hole and my second cut, I had the confidence to work much faster and I had the whole canopy trimmed and fitted in about 3 hours. It came out perfectly and looked like it was moulded exactly the size and with the holes perfectly placed (much easier to do that with the holes in the frame already drilled.      

I wouldn’t think twice now about getting sheets of acrylic and cutting, drilling and countersinking them myself.  You can practice on a few scraps until you perfect your technique but if you can cut a sheet of plywood, you can cut this stuff.

Re: Windscreen Replacement

 

Including all material, all labor, and including routing for a gasket and new gasket on the port side windshield, and including painting a 30mm stripe around 3 of the 4, will be around 1000 euro, including installation.

Of course, prices will vary from place-to-place. The difference in price will mostly be the difference in profit.

Re: asymmetrical spinnaker

 

Is there a reseason why you do not simply use the center roller, taking the tack line under the roller, and forgetting about the line fairlead?

Re: Steering wheel removal

Patrick McAneny
 

Slavko, 
I removed mine probably ten years ago to send it out to have it coated by Color Wheels ,a vinyl coating that has held up very well and still looks new. As to getting the wheel off, it took a lot of force to get it off. If I remember correctly I put stainless hose clamps around the spokes and used a prop puller to apply the force necessary to get it off. It took much more force and time than I expected to get it to pop off. I think I would now use deneema line instead of clamps ,if I removed it again .
Hope this helps,
Pat

Hello,

I do not what break anything so advice will be helpful. Wheel will be send to company that will put new leather  cover.

To all,

I have a 1988 Mango and I find that the thru hull which feeds the forward head no longer has a working handle ( it moves but does not allow water in). This thru hull also supplies the anchor wash. Luckily, I’m about to pull the boat for bottom painting and commissioning. Does anyone know the size of this thru hull?

Thank you
