I have the specs on FRP Laminates / Hull and Deck, for my Lancer. These numbers look like the hull is built sturdy. They are:Topside Plating - .636"Bottom & Shear Plating - .668"Bilge & Keel Top Plating - .769"Deck Plating - .474I have some question I hope can be answered.1. What is the differece between "Topside Plating" and "Deck Plating"?2. Is the Top Side Plating the hull above the water line?3. Would the Bottom & Sheer Plating be below the water line?4. I am assuming the Bilge & Keel Plating is just that, the keel and very bottom of the hull around the keel. Is that correct?Thanks for any assistance.
