fiberglass ply bulkheads again

My project....I will be posting photos.

Its only a 23 foot keel yacht...but i wanna post my journey so others can see what is totally possible if you are keen. By the same token, other projects on this site are way bigger and more $$$ and mine pales in comparison.

I've got a massive job ahead. Ive already demolished the cabin.

good boat...but the usual "terrible workmanship at the factory" thing. (back in the 70's or 80's)

this boat has not moved from a private jetty for 7 (count them) years. Ropes all old and perished from the sun etc. Gunnel Paint worn from fenders. crazy.

boat has Some kind of white foam core deck

plywood bulkhead up front and ply deck head stringers.

mast step is a totally rotten piece of plywood on its side. sad.

cabin stringers rotted to mud stage (only two of them.... five inch wide ply on its side glassed in)

basically...everything on this boat is fine...the core has obviously been exposed to damp but is fine/dry and not de-laminated (yet), the hull is fine

but any plywood parts were factory fitted and exposed to any water. No deck fittings sealed. mast step not sealed, stanchions not sealed, etc etc etc.

im fine with tabbing and sealing ply and epoxy v's poly and all the usual things......

But!!......the first two inches of my under mast deck stringer sits two inches into a two inch thick foam deck core. (port to starboard and is held up via 2 compression posts)

if i seal a ply or hardwood stringer with penetrating resin and then glass n resin ...im still putting a wood stringer in a core that might get wet again and is out of sight.

If you had to fit a new stringer/bulkhead into a known...and future possible wet area...what would you do?

what material would you use?

wood might last for ten years...or more...and be totally fine....but we all want the perfect solution or not to worry.

dunno what to do....?

anyone?

Re: fiberglass ply bulkheads again

I would be fixing the leaks and putting plywood back in and they will most likely outlive you as the boats is not supposed to leak somebody just let it get that way



find the damage fix the leaks





fix the damage




Paint the damage go sailing



Smile and enjoy as much as you can

If a dirty bottom slows you down what do you think it does to your boat

Re: fiberglass ply bulkheads again

Yep.... Think that's it.
I'm just a bit paranoid after reading the endless posts around the net
Of folks getting scientific and arguing about crazy things concerning resin
And ply that will prob not even happen. Lots of talk and prob no action!

Thanks Tommays for the sanity check.

I like the yellow shirt! Very nice!
