Hobby Lobby should have it. Or your local HS You'll spend over $60 in wood.

Try Woodcraft. I bought some plywood from them. Not sure if they are maine grade but once you glass or epoxy them over, it should be all good.

Some Home Depot stores will stock (or can order in) Baltic birch ply which is still fairly inexpensive and will get the job done just fine. It usually comes in 5x5' sheets but I've seen it here at a local home Depot in more manageable 24" wide sheets, both 1/4" and 1/8". Not sure about the 3/16". Baltic birch is commonly used in cabinetry construction.

Any of you guys have problems not using marine plywood for your hulls?

I have no problems using Birch,Maple plywoods. Marine plywoods are resistant to dry rot and not needed in our models unless you plan on mooring it.
