First Quad Longboard - Is My Design on Track?

My design dilemmas are over. I have gone ahead and shaped the board. After much deliberation I decided that a flat bottom was more appropriate to the board’s needs than concaves. Lots of roll in the nose, flat bottom, lots of vee in the tail section, downturned pinched rails. I think it will go.

Thanks to all for your input.

Fin placement - here is my drawing showing fin positions using McKee’s formula for longboards.

and then

Rear fins - Cant 1/8" - Toe 0 degrees

Front Fins - Cant 1/4" - Toe 6 degrees

 

Looks right to me. If it basically works I’ll be happy. I have noticed that quad fin placement can get very complicated. Trying to keep it simple.

 

The finished board. I feel some pleasure.
