Haven't had time to work out area too much study, but roughly sqr( 450^2 + 50^2 + 60^2) x 8
The tips were to try reduce the turbulence at the end of the foil, similar to what is on some plane wings. But I guess in water it might not be necessary.
Until its made, who knows haha
No, this would be my first.
Is the rear wing usually symmetrical in profile?
