Thanks, guys - it's getting close...
TT - I designed the pattern/layout so that the gray only touches the hull in a few places since I knew I wouldn't find a vinyl that matched the hull exactly. I think the white accent & black piping trick the eyes into thinking they're the same color gray. Only time will tell how functional the new layout is for moving about. The pictures are deceiving - I've got ~18" between the rear bench seats and back of the doghouse.
I received the special hinges needed for the bimini, but have to wait until the tower's up to figure my angles & measurements. The angled wishbone front half of my TitanII is gonna make things interesting... Cool is the idea, but it's just an idea - I only hope my execution is as good as yours.
Thanks Salty, but no need to kid - the armrests and top ledge of the rear bench were designed just for that purpose. The whole seatback/armrest assembly is a sandwiched construction of 2x2 and 1/2" ply with minimal foam on the top face to support a sundeck. However, once I built it - the armrests, cupholders, and doghouse had the rear seat bottom trapped (again, best laid plans & all that). So I split it into two pieces, but still plan on having the rear bench(s) convertible to a sundeck and to allow the two MC X-2 450# sacs underneath to fill to their full 20" of height for surfing. I'm gonna add some hinged braces to the underside of the seats that fold down to support the middle edges when in the "up" position. We'll soon find out how/if it all works out.
Jet - I'll get some better pics for you once I've got it back for the last time. The seat base is rectangular with 72" clear length inside for ski storage. The backrest piece has angled 2x2 uprights with a 2x4 top and skinned in 1/2" ply all mounted on a 1/2" ply base that is bolted to the base. It's hollow inside with storage access through the top hinged backrest. The seat bottom lifts out to access the base storage (although I made the blasted rear armrests too long trying to cover existing holes & have to lift the backrest cushion up to lift the bottom out).
