Fiberglassing in marine ply

[BadGoblin]

Hi

I would like to cut out ribs from 9mm marine ply to put into a 8ft fiberglass hull to provide more stability and rigidity. Then I want to put in a flat floor/deck. How do I go about securing the ribs and floor in? Do I fiberglass them in? After i've put in the floor, I'd like to carpet it like a bass boat. How does the carpet stick to the marine ply? Is there any steps i'm missing out on? Sorry for all the newbie questions... Any help will be appriciated.

Thanks

Yes, you should glass the frames in with several tapered layers of glass epoxy. Epoxy, not poly!

No, do´nt lay a carpet on any boat structure! It is a water trap, and one of the biggest mistakes in boatbuilding. EVERY material deteriorates under a carpet.

Encapsulate every piece of wood / ply that goes into the boat if it is worth the effort (if the intended use will be years, not month).
Did you say 8ft? thats not much.............

However, you're adding a lot of weight to the boat and creating a lot more work than necessary. The rigidity, if the boat needs it, can be achieved by glassing in a center seat box that goes all the way to the boat's bottom. also good for more flotation. Also stiffening up the gunwales can help.
Raising the floor with a plywood pan is going to put your knees into your chin I think.

As Apex said, 8ft is not a lot of space so i'm trying to keep as much of it as possible free. the boat is under 40kgs at the moment so another 10 or so should be ok...?

What are the alternatives to the carpet?

the floor would only be a few mm from the highest point on the current floor. the boat has a cathedral hull and the floor is that shape. so standing comfortable is difficult.

Hey guy according to a previous post you do not need several layers of tapered glass two or three layers will be just fine .

So three are not several?

Depends on what side of the framing you are talking about

Two are a couple. Three or four are a few. Five to eleven are several. Twelve plus are a dozen or more.
