Default Marine Grade Plywood

Help!! We're new to PDX and Oregon and are not sure where to get marine grade plywood. Parr has some 1/2inch for $68 a sheet. Does anyone know of other places?
Thanks!!

I scored a sheet for a decent price at Mr. Plywood several years ago for a very good price. And actually, the price you mentioned for marine ply isn't terrible.

Found this in a Google Search;

Quote:
Marine-grade plywood is made entirely of Douglas-fir or Western Larch. The grade of all plies of veneer is B or better. B-grade veneer may have knots but no knotholes. A-grade veneer has no knots or knotholes. Both A and B grade may contain wood or synthetic patches. Panels are sanded on both faces or Medium Density Overlay (MDO) or High Density Overlay (HDO). The maximum core-gap size permitted is 1/8 inch. Its exposure durability rating is EXTERIOR and the glue used is a fully waterproof structural adhesive. It is considered a "premium" panel grade for use in situations where these characteristics are required. It is available in 4x8-foot sheets of 1/4, 3/8, 1/2, 5/8 and 3/4-inch thickness. Sheets up to 5x12-feet are also available. Available grades are A-A, A-B, B-B (face-back), MDO and HDO.

It's my understanding that most plywoods have "voids", or holes in individual veneers that when glued together actually can cause weak spots in the board. You don't want that in a marine application hence the "voids" in the individual veneers are patched before being glued together. Don't skimp get the best there is!!!!

Best place to get marine plywood is Crosscut at 3065 NW Front Ave, Portland, OR 97210. phone # 503-224-9663. They have whatever thickness you need, and reasonable prices. That's where alot of the boatbuilders buy their marine plywood.

bfox: Do a search for Replacement Floor In Driftboat. There was a post by Spindrifter on 12-14-04 pertaining to plywood with a number of responses that you may find helpful. Good luck and happy fishing!

bfox.... You never mentioned what application your were using it for. If floor replacement, it's probably your cheapest deal, but for smaller areas, there's a product called Starboard. They make synthetic cutting boards out of the stuff, and it cuts and shapes with woodworking tools.

I'm going to use it to replace the covers on the sides of my transom. It's currently covered with carpet on marine plywood, and I hate carpet! Best of luck with it.... Tim

timinthegorge---careful with some of that stuff, the expansion and contraction ratio is herendous--cracking around the screw holes and if you buy white it may discolor--I'm dealing with this right now.
