How difficult of a repair is this?

Re: How difficult of a repair is this?

Post #14 gives a couple of hints.I suspect the keel may be fastened with allthread-always a risk of leaks along the thread.I also have a feeling there may be a core void in the ply nearby.

Well I managed to find a pic and this is new unfortunately. So starting to try and figure out the repair and when/how I’ll do it. Unfortunately I’m trailer less at the moment and moonbeam is moored. There’s no water leaking through I’ve verified, seems to not be growing. Hoping the wood swelled and sealed a bit and it’ll be ok for a month or two. How long does delaminating and worse conditions usually take to build?

I had similar looking spots in my bilge, turned out it was checking in the epoxy that let water seep in. If it isn't getting worse you might be able to just sand it back and let it dry out.

Don’t expect ply to “swell and seal”, it’s not like a seam that compresses when a plank swells. If the paint or epoxy or whatever is on the exterior is damaged it will more likely just continue to wick water - particularly if it is a cheap ply. If it’s not marine ply you could also expect the ply laminations to fail.

My original thoughts in post #2 stand - if you’re worried about it get it out of the water, sand back the exterior coating, check the condition of the ply - ie is it delaminating or just damp? Let it dry out and re-coat it.

If the ply is dodgy I could understand you wanting to try and preserve the appearance of the interior finish so you could try sanding back any dodgy wood carefully to good wood and scarf in a new piece on the outside to fill the divot - or even just patch it with a few layers of fibreglass and epoxy to build its back to level.

It’s Meranti, I don’t care about the look this has floorboards so you can’t see it. I can’t get the boat out at the moment and I’m unsure when I should worry. I’m supposed to do a 100 mile sail in July and wondering if I’m stupid to leave the boat in the water that long or not.

Your call really but as the saying goes with boating - "reef early"
