They are strong but cost prohibitive and I believe a little too stiff for a backbone in a fiberglass boat.  Besides if it has a center stringer, you will need a piece that is at least 12" wide.  That may be a tall order ($$$) in the hardwoods.  Then there are composites.  More money.  If you need longer than an 8' run you make a nice scarf joint in the plywood and reinforce with glass.  What glass did you buy? and what is your layup schedule?

 I bought West Systems 105 and 206 the stringer was just plain lumber I swear it is pine it was really cheap wood the deck was 4 by 4 plywood squares.
