It’s 38cm more than I have on my trailers, I have them starting directly underneath as it gives better support to the transom. [emoji848]

This ^^ it should be below the transom with last roller.

Probably hasn't helped the transom problem you face, easy fix though if the trailer is correct size, move boat and axle forward.

Hmm I wonder. Solution for that bar buying a new trailer? Extended roller arms with more rollers to go further towards transom?

As part of the repair works looking at a stainless plate so hopefully won’t have problems with cracking in the gelcoat again

That's a very good result.

I'd agree with jwalker on the repair. My only suggestion is you could use epoxy rather than polyester / vinylester resin. If you do, you can't use powder bound CSM - the epoxy doesn't dissolve the powder.

Trailer - it sounds like you need to move the boat forwards on the trailer if possible. Dependent on nose weight, you may also need to move the axle(s) forward as well.

This is what I set mine like

Thanks, I’ll look at how to move the boat forward to help the cracks not appear again. When I get to it I may start a different thread for advice on that [emoji106]

I agree with JW. That is a classic polyester/vinylester resin repair and will allow you to gel coat or topcoat the same colour as transom

I prefer epoxy as it’s a superior bond on old surfaces, but epoxy isn’t UV stable so you would have to coat it with paint or similar. Not many paints take being submersed or sat in water as they pickle. So if this area will not be submerses you could go epoxy, Polyester might still be the easier choice for you here. It’s also a lot cheaper material. Prep has to be good with polyester. Sand 40/80 grit all over, wipe with acetone immediately before starting repair. Keep it all spotless. Polyester doesn’t really stick to wood, so ur mearly encapsulating it, so make sure all csm is compacted. Epoxy does stick to wood FYI.

Epoxy has superior cross linking properties, Polyester resin layup needs the CSM interlinking fibres to cross link. If using epoxy use a lovely 45/45 biaxial fabric for substantially better bond and strength. CSM is wasted on epoxy and just makes a resin rich repair.

The only ways I may deviate from JW repair in polyester or epoxy is, I like to make my own fillers, and I’d fill the grain in on the top of the wood with a mix of resin and cabosil to form a sticky filler like mayonnaise, this would bulk any voids or holes in the wood top. It makes a nice sticky surface to stick your first csm or cloth too, so literally a thin scraping all over, with an old credit card as a spatula. Sounds scary at first, so you could use a marine filler from chandlery, but once you have cabosil in your shed you will feel much more macho

I have had a couple of bad experiences with gel top coat mixes not curing when using wax. So I now prefer pva (blue, not the plasterers type). I put it in a cheap Tesco water spray bottle. Let the gel coat set for half hour then spray a fine mist all over the last coat of gel coat. Wait normal curing time, then scrub off with warm water.

You can get 15 MM chopped strands no bonding on them also a wood primer which soaks into the ply. You could also flow coat over the repair or the lot. East coast resin supplies have all the stuff plus videos showing you different projects and if you ring them up they give good advice vaccume bonding might be the way to go too

Looks like someone's looking after you!....not often the Transom is actually better than it looks when you start digging Rot

I agree maximus, didn’t know what I would find!

Don’t pay for next da6 delivery at ecs.... it arrives a lot later than you would call next day. CFS seem more honest, but ECS better advise.
