Floor for 16' Aluminum boat

[edandq]

I'm in the process of restoring a 1970 16' Aluminum Starcraft. The hull is in fantastic shape with no leaks, but the floor was shot. I removed it and amd getting ready to replace it. I've bought marine grade plywood, and will cover it with marine grade vinyl when installed. My question is this. How do I treat the wood before I lay the flooring over it, or should I? I want to keep the cost down, but just dont' know what product(s) to use.

Saturate with epoxy resin.

Curious about "marine grade" plywood.<br /><br />What kind of a place did you buy it from? Have read past posts saying that it doesn't really exist.<br /><br />I have always bought exterior grade construction plywood, and then saturated it with epoxy resin, as SoLittle suggested.

Re: Floor for 16' Aluminum boat

Well, I got the marine grade plywood at a local lumber store for boats (live out near Seattle)...I've read the posts supporting both for and against, and the price difference wasn't that much so I went with the marine ply. As for saturating with expoxy resin, I've never used it. Do I need to mix it? Is there a particular brand? An easy way to do it? Any tips will be wonderfull appreciated. Thanks so far for the responses!

Is it made with BC fir or spruce? The fir is much better in the long haul under wet conditions.<br />I suppose to be marine grade, it must be fir.<br /><br />I would treat the cut edges before installing it.

It's made with Doug Fir... you say to treat the edges and treat before cut, are in concurrance with others and say treat with epoxy?

Re: Floor for 16' Aluminum boat

Wood preservative used in making pressure treated wood (green stuff) would be my choice. It penetrates into the wood and cannot crack or wear off. I'd stain it over top, bottom, and the cuts. It will keep it from rotting.<br /><br />Here are some sites on marine plywood that may be of interest.<br /><br /> http://www.westsystem.com/webpages/epoxyworks/18/plywood.html <br /><br /> http://www.glen-l.com/wood-plywood/marine-plywood.html

go to a welding shop and have them weld an aluminum sheet the thickness of a road sign instead of wood. I had this done and no more problems. cover with carpeting .

The Lund boat that I had,had pressure treated plywood and then like a vynil flooring. Held up for 6 years and the fella up street still has the same floor

missed_shot<br />Just curious- <br />Does the boat seem any louder without the dampening effect of plywood.<br />How is the aluminum to stand on & does it flex more than the plywood. I realize you put carpet on it.<br />And finally what was the aprox. cost.<br />Of all the posts I've read about replacing floors I've never heard about using alum. It sounds interesting.

Re: Floor for 16' Aluminum boat

Appreciate all the responses. The floor I removed was 35 years old, and it wasn't coated in epoxy. That being said, I think I'll just treat the wood, use the good glue for the vinyl, and be done with it. If it lasts 10 years, I'll be happy, doubt I'll have the boat that long. I probably could have went with a fancy composite or aluminum, but didn't think of it at the time. Now I just have to figure out how to attach the wood. I will probably just screw, I hear the add weight, but it can't be that much...

Ed - I don't think it sounds any louder than wood. I put the blue building insulation under the aluminum between the ribs. It deadens the sound and adds a little to the flotation incase I forget to put the drain plug in .<br />The ribs on my boat were fairly close so I have a solid floor.

missed-shot<br />Thanks for the reply. I'll put that into the mix for deciding how to approach my spring project. The weather is going to be in the 50's this weekend. It won't be long now.

Re: Floor for 16' Aluminum boat

I advise against using the wood treatment used in pressure treated plywood.
It is very corrosive when put against aluminum. If you are using vinyl over
the floor the vinyl will give some good protection. I would use a latex base paint and put a couple coats especially on the edges. That will give you a good seal and not effect the bond when you put your vinyl floor down.
