General wood question...

I was looking for some scrap wood to make the decks for my canoe and came across an old oak panel in my basement (the panel is made of edge glued oak boards about 3" wide (each)) the individual boards in the panel were glued with the grain alternating to avoid warping, but years in my moist basement have created an even, circular warp of about 3/4" over the full 18" width.

I was just about to pitch it in the trash when the thought struck me - what an easy way to make a nice cambered deck! The camber is already built into the material.

My concern is that the oak, already having begun to warp, is now unstable and will either continue to warp (or choose to straighten out) after I install it, thus deforming my hull. Should I use it, or should I follow through with my first instinct and throw it away?

Interesting off topic aside - my concern is due to the fact that wood is very powerful when affected by moisture. One ancient quarrying technique was to drive oak wedges into cracks in the rock, pour water on the wedges, then step aside and let the expanding wood split away big slabs of stone.
