Construction on my Night Heron starts tonight!

I'm still not entirely sure how I'm going to do my fiberglassing schedule. I plan on 6 oz glass on the outside of the hull, with an extra 2" tape along the keel for abrasion... nothing exotic here. However, what do you think of a very light (like 2 oz) glass covering for the interior and topsides, reinforced underneath with 1 inch kevlar or carbon tape laid out like stringers? I'd probably put five stringers lenthwise along the hull, and then around stress points like hatches, the back deck, and the cockpit, run longitudinal strips of the tape to protect the shape.

As I paddle in a lot of rough water (the S.F. Bay and northern CA is no picnic!) I can't afford to sacrifice durability, but I'm very interested in minimizing the weight. Let me know what you think - thank you.
