Wood ?

Use cabinet grade plywood and coat it with resin all around, both sides and all edges. Don't use treated the resin will not stick to it. once the piece is coated and sealed up then mount it in the floor and use mat and woven gla$$ to build up the thickness to level out the new section of floor with the rest of the floor. Another option is using a composite material call starboard all you have to do with it is seal up the gaps but it's a little pricey compared to the plywood and resin route it would be that much more but a little it will save some time as well. West marine sells the starboard material so check on pices there.

TRBenj- very informative thread on the floor replacement. Soup to nuts, how long did it take you to complete? How's it holding up? Would you do anything different?

92, its holding up great- although Ive put <10 hrs on the boat since! I threw the old carpet and interior back in for the NE reunion in August, and havent even gotten around to installing the new carpet yet. I expect the repair to last a long time- I tried to do it right so I never have to do the work again, at least on this boat.

The only things I may have done differently were:

1. I wouldnt use 5200 to seal up the bulkhead (I learned later resin wont stick to it). I would have used thickened resin to create the fillet instead.

2. I would have used woven roving over the plywood to add thickness much more quickly. I have at least 3 layers of mat/cloth on there (more around the edges) but it may be a touch lower than the rest of the floor.

Other than that, Im happy with the way it turned out. I will also be gla$$ing down some thin plywood to the sides of the hull in strategic locations before I re-carpet. Ill use them to mount things (possibly amps, speaker enclosures or braces for the combing pads). Thats actually how the storage pocket near the driver is mounted.

Its been discussed here before that marine plywood simpy has fewer voids than structural plywood. Both utilize waterproof glue. The extra cost of marine plywood isnt worth it for a floor project.

Tim, are you going to get a picture of the mirror mount for David?
