Ok here is a very basic, but successful setup.
With at nose- 7"
With at 50%- 60cm
With at tail- 18"
Tail to 27" off- Flat
From 27" off Tail Gradual rocker to Nose -6.5"
3.5" Thickness from tail to 50% of board length, from there taper to 1"
Top and bottom can be flat
Fin boxes Measured to rear of box
Rear 3" off tail
Front 20" off Tail
Fin Boxes Measured off Rail Apex to Outer edge of box (center of box)
Front and Rear 2"
Rear insert about 4.5" off tail and about 5.5" off rail apex (6.5" spread)
Front strap screw off rail 3". About a 45 degree and angle for front straps. Total stance width between rear screw of front strap and front screw of rear strap (the stance) about 20"
This is an average if you were to measure boards from several brands. My 2 cents, go for a tri instead. If so move front fin box back one inch.
Ok I have given away enough now. Enjoy building! Take a look at the Tech section for basic step by step directions.http://kiteracing.com/Shaping_Room.html
