KeymasterLast summer I was given a GP14 – an old club boat that hadn’t been used for some years. It’s a grp boat, I haven’t located the hull number yet but I think it’s a 1980s mark 2. I replaced some halyards and took it out a few times – all seemed good apart from the centreboard refused to stay down. I have removed it with a view to replacing the centreboard brake (the rubber tube has become quite hardened) but I see now it needs some more renovation. It’s been repaired in the past – looks like it’s been taken apart at a joint down the middle and re-glued. There’s also a split across one of the boards that has been glued. Both repairs appear to be holding up – but there are a couple of new gaps opened up between the joints at the top of the centreboard. The belt and braces approach would be to take the boards apart, plane the joints and re-glue – but I have neither the tools nor the expertise to do this (and I’d probably cause more damage in the process). Instead I’m looking to patch it up again, sand and revarnish. I’ve searched online, but the advice is varied and conflicting. My options are:
a) work some epoxy into the gaps and use clamps to close them up as much as possible while it sets. I have some large sash clamps that would do the job. My only concern is that it I’m not sure how much the gaps will close, and if they do it would leave the wood stressed. Is this going to be a problem?
b) I’ve read somewhere that gaps like these, at the joints, are due to shrinkage and sometimes close up again when the boat is in the water more regularly. The advice is revarnish, but not worry about the gaps. I’m sceptical about this. The gaps are at the end that won’t be immersed in the water. Some suggest using a flexible filler in the gaps in case the boards expand in future.
c) fill the gaps with thickened epoxy and revarnish.
Any thoughts? I’ve attached some photos.
