I will be doing the silicone next week.

I will let you know how it goes.

Hi Eric:

I reviewed the specifications and data sheet for that product and it looks like their recommendation is sound.  It is neutral cure, and has good environmental exposure specs. 

Let us know how it works out.  I still have a full bag (a couple of hundred) of those plugs but I must admit that I get tired of timing them to length and installing them as they only last about 5 years.  I do believe that it is important to prevent water intrusion into those holes.  The stainless screws, aluminum track and mild steel backing plates is a bad combination when water gets between those metals. 

All the best,

Ballooner

Patrick McAneny
 

I have never had an opportunity to sail down wind using the ballooner other than a couple of short hops years ago. I may have an opportunity to use it between the BVIs and Bahamas. A couple of questions . How many degrees either side of downwind can you sail with the ballooner and at what apparent wind would you begin to reef sails ?
Thanks ,

Re: [Amel Yacht Owners] Genoa sheet cars

Alan Leslie
 

So,in view of no comment on this issue, I assume that it is possible to remove the block at the FWD end of the genoa track to allow the car to be removed.
I can barely turn the eye bolt that goes through the axis of the the pulley block.
Could one of you at least confirm that is how it is removed...is there a nut under the gunwale, or does it screw into a steel plate ....or.....
AND what about the aft bolt on that block ....what's that connected to .... if anything ??
Thanks for advice

Hi Ian

When we did the gear boxes we just did the brushes

However both the I mast furler and Genoa curlers died. The latter full of water the former was a short in the armature 

Bugger!  So I have just had both motors rebuilt.  (We are heading in to the pacific early June)

The guy who dealt to the motors said he could build two new ones if I wanted but someone in the Amel group when I asked if anyone new a source for the motors response that I should just rebuild cause that’s what they did......so I followed that advice. I now have two completely rebuilt motors at  cost of $1100 NZ or about us$750

Re: [Amel Yacht Owners] Genoa sheet track plugs

James Alton
 

Gary,

   That is a good point about not using an acid based Silicone on Aluminum.  I have not used the 737 but will give that one a try thanks for the tip.  I do have long term experience with the Dow Corning 3145 Grey silicone caulking on boats caulking in large windows, deck hardware etc.. This is a Mil-spec non acid based caulking that can be used even for electrical work.  This caulking has higher adhesion and elongation qualities than any other silicones that I am familiar with.  The UV and weathering resistance is the best I have seen in a silicone but this only applies to the Grey (there is also a clear version which is also a bit runny) which colour wise blends in pretty well with the aluminum Genoa tracks.   My bulk supplier has a minimum so when I just need a small amount I normally buy it on Ebay, in fact a small tube arrived just today.

   Thanks Gary for sharing your knowledge base.  I especially like the slider seal that you came up with.  My boat has what may be the original slider that has become hard and the noise that the slider makes in use is almost blood curdling.  (grin)  I really need to get that changed this season!

Hi Eric,

We are trying an alternative to the plastic plugs that deteriorate with sunlight.

After cleaning out the decomposed plugs and dust, we filled the hole with white silicone. We filled considerably higher than the surface of the track, and after it cured a few days cut off the silicone with a razor flush with the top of the track. It’s a pretty neat job, and we’ll see how it last.

Hi Danny

We had a double whammy in that there was gel coat cracking under the track where (we think) the backing plate had expanded AND the car inserts had disintegrated and needed replacing. We did it as part of a fit out in Tunisia.. even with an impact driver we still couldn't get the whole track off but managed to free the track enough to slide the cars off.
Heres the link to the video, time stamped at the track repair.. hope it helps

Good information Gary.

Looking up the specs is see this product uses atmospheric moisture to cure. Don’t know if that is “natural”. No mention of “acid” cure.

Recommended for exterior aluminum glazing systems. Anyway, its done and we will see.
