Where are you locating the fins = forward like a kneeboard or further back?

take a look at the pencil lines in this pic..they are proportionate to the wing, to assist with pivot. Certainly NOT on the tail
but definitely back 1/3rd

what dimensions and volume is that? It looks amazing

thx mate..it's 4'11"x21 1/2"
sorry, it's handshaped and can't give you a litreage Tim, having said that
it would be 2 5/8" thick minm, so you can always use a Shape3D google search to get an idea.Surfing prone? We're never totally out of the water (but see my pic to follow) so, buoyancy isn't necessarily, critical

Some times it pays not to ask questions...7'0" belly board

This is a 7'0" Pintail, totally so the surfer is above the water, and planing

water entry is essential (with anything you surf)
but prone? Keep things like chines/edges to make sure your rails lift and stay high 
..but let water IN everywhere else ❤..
