Re: Deck Boat Projesct
I have the exact same boat and model year!
A great boat, I like it so much I also have the same boat in a 1996 model year. Which has the one piece fiberglass floor.
My 1993 deck was redone by the previous owner. They gave me some redo pics and I did not see any foam in place nor have I seen any installed. Although I would have to pull the deck to see for sure.
It also appears that they encased the crossmembers with resin.
I wish they had installed more crossmembers as there is not enough support between what there is now for the 3/4" treated plywood. Thus allowing the seams to pull away from each other. The floor was covered with something that peels and pops off of the screw heads. The covering (as far as I can tell)no glass mat or woven materials were used on top of the plywood. And the edges were not sealed were the rubrail molding is screwed into the edge of the plywood thru the hull lip. Looks like eggshell and about as thick.
When the PO re-did the deck, they installed a 25gallon fuel tank about 1 foot from the stern below deck on each side. The rear bench seat was not re-installed thus adding about 2.5 feet of floor space.
We run her with the original dining table and two Todd brand reversable benches at the table. For the forward seating, we use whatever patio chairs and loungers we like. That way we can off load them to the beach if we like or use them at the house.
In the near future, I will be re-habing the 1996 model which was a hurricane Katrina victim. Transfering outboard and other "good stuff" from the 1993.
If the floor on the 1993 needs to be redone in order to make it sell, I am seriously thinking about not using plywood.
Since it has crossmembers already, I might add some more then use conventional 5/4x6 deckboards. Either treated wood or even the hi-tech compostite types. It is after all a "deckboat" haha.
Unlike a conventional pontoon, you don't get underdeck splash from the pontoons. Deckboards would allow topside drainage via the existing configuration to the bilge pumps at the stern. Deckboards would not delaminate when soaked either like plywood. Stain it with deck stain once a year. As far as weigh differences, I think it would be about the same as using the 3/4" plywood and last a lot longer. It would also be a whole lot easier to replace one bad deckboard or to remove one or two in order to get to something below deck.
I believe it is futile to try and waterproof the deck (plywood). Especially when the underside of the deck is exposed to the moisture that gets below deck anyways. Down here, the below deck chamber becomes a greenhouse for black mold unless you can spray it down with fungucide on a regular basis.
