so i've put some time and effort into the hull, brightwork, and structural components on this '56 thompson.

unfortunately i have a little ripple. that wasnt there when i varnished. It appears as though the veneer has seperated from the other plys.

i noticed it was chipped at the edge before i varnished, so i applied a small bit of famo, and sanded/swore/varnished

all coats went on fine, and there appeared to be no issues. 6 months later i have a ripple, and it's getting bigger. the seperation is visible to the naked eye, and I can get a syringe under it, and with a little coaxing i could fix it somehow (see #3)

I believe I have a few options. I would love to hear opinions on my options and new options would be much appreciated.

1. I can cut out the 6" stripe of bubbly veneer and replace it with a contrasting (blond) veneer. which will result in a nice racing stripe. it may result in a fairly nice appearance. I am not certain how to cleanly remove the ripply veneer and replace it, although i believe it involves a razor, contact cement, sanding and more varnish
the end result will probably be something like this:

2. I can replace the entire port side of the decking. (ie mahogany plywood/laminate trimmer/etc)

3. I can fix the rippling veneer somehow. (your help in how i might do that is much appreciated) I would rather start with this option if it viable, as I still have more structural work to finish on this boat, and a quick fix would be acceptable for a short period of time (one season) as I already have my winter booked with all of the ribs/chines/etc

thanks

Once you're sure the delamination is stable and corrected,you could add a narrow covering board either around the whole boat or just the bow section.

i dont think the delamination is stable. I think if i remove the area immediately surrounduing the delamination, i might be ok.(hence the racing stripe)


1. i think it is growing, if i do nothing, i will certainly be replacing that half of the bow.
2. what is a "covering board"?

A contrasting darkness of the same wood as the veneer wouldn't be bad either. Even the grain in a different direction would still be a contrast. Nice boat and bass

Hate to tell you this, but it is possible that you will have to replace all the plywood on your deck. The deck plywood is not the best to begin with. It's really easier just to replace everything than to mess around.

Probably easier than trying a repair of spot.

Speaking of really bad booze, a client is bringing me a bottle of Screech from Canada. Rum of dubious merit from Newfoundland.

It's weird how adding a stripe of lighter color turns boats into guitars. And it's not even a bass boat.

pc ford, yeah. that was my initial assumption.

angwood, i figured a racing stripe would make it go faster too.

don't think its dud plywood. it worked pretty good for the first 50 yrs
