Marine Grade fir plywood

[WildBill]

Most Lumber yards carry it. The box stores carry it, if they do not have it in stock they will get it for you. You will find quite a price difference from store to store. I found upwards of $20.00 per sheet difference. Call them first and ask how much it is, then go a look at it and make sure it is really a marine grade plywood. You will find there are salesman who don't know or can explain the difference. I have seen and heard of friends who thought they ordered and purchased mp ply but did not. I purchased my mp ply from an 84 Lumber Store here in central Florida; the 1/2'' for $49.95 a sheet and the 3/4'' for $59.95 a sheet. You can google it for your area if all else fails. You can also learn and understand how it's made and what makes it different from other types of ply.
Don't forget there are some high end plywoods such as Okume.

Good Luck Bill
