Looking for some 1/2 inch thick by 12 foot long plywood. Anyone know where I could get this at in mid Michigan?

Boat floor, the original is one piece and I would like to do it that way again. I only want to do this once.

Thanks I know I will have to epoxy it or glass it to water proof.

Thicker would be nice but I'm not trying to rebuild the whole boat, just replace the floor. If I went thicker all the panels and trims would have to be cut down and I'm not into all that. I just want a quick turn around so I can use the boat, not look at it for a month or 2 because I started to change stuff.

they do make a "marine grade plywood" it has an extra ply in it as well as uses water proof glue, as far as where to get it... try calling the four winns plant in cadilac they should be able to help you, or talk to your local lumber yard, they might be able to order you a sheet

If the boat floor is that long, it is probably more than 4' wide???? Point is,... you will have a joint anyway???
I would use green treated 4X8 and block and glue under the joint at the 8' point.
I tend to do a job that is strong yet economical,....but that obviously has its limits.....but if the floor is being covered by glass and or carpet I have used the green treated plywood with great results.
I have done several pontoon boats and fish/ski boats.

Unless you use your boat differently than most (trailered, drained and dried after each use), anything but marine grade plywood won't hold up and you will be doing the job again in 5 years. The high humidity found in a boat floor boards will de-lamination the wood quickly. No coating will prevent this moisture from getting into the wood and glue to do the de-lamination.

So here is my suggestion. Either use some plastic type boarding (thinking of that composite decking gray in color that is available at the box stores) that is not subject to moisture de-lamination, or use marine planking such as teak or other wood product that is not a composite product. Teak has been used for this for many years and is not subject to rotting or de-laminations. It will require some maintenance from time to time, but it will reward you with some very nice looking flooring.

Unless you can find something that is not affected by high moisture content, you won't be happy with what will happen to your job sooner rather than later.

I found a sheet 3/4" x 5' x 12' and its under $200, now I have to decide if that's what I want to do, I will only need one sheet of this. I cannot use green treat because its an aluminum boat and treated has copper in it and they don't play nice together. The floor is in three sections so they are under 3 feet wide. I have talked to a few boat dealers since I first posted this and have a few different ideas on what to do and what epoxy to use for sealing.

I guess my jobs are the exception to your "5 year rule" LOL because I have used the green treated plywood product on projects from boat repairs to All Weather wood Foundation systems (basements & crawl spaces) witout a single failure going back 20 years.

The composite decking products lack strength. If plywood was used in the manufacturing of the boat it also probably is part of the structural integrity of the entire vessel.
