Specifically, I'd like to know about the 28' Sport Express's stringer and hull construction.
Is the hull solid fiberglass? Are the stringers wood construction?
I understand the 30' Tournament/Sportsman had no wood in the construction of the stringers.
What other models of CC Commanders had no wood in their stringers?
I started to reply that all the glass Commanders of the new, 1964 to 197? series were strictly glass then realized this hull being deep vee may be different. The stringers fwd of the engine room will have weep holes to the bilge which obviously lets you in on the secret of hollow or wrapped.
Good luck, welcome aboard and keep us posted.
I have one I'm restoring. hollow box beam heavy fiberglass construction.
