Cant angle for a quad

General Discussion

Aloha Shapers,
I am shaping me a lil surfboard 5’0x 20 1/2" x 2 5/6" that I want to set up in quad configuration. For fins placement I followed Mckee formula. Front fins 10 11/16" from the tail and back fins 4 15/16" from the tail. Toe-in front fin:1/4" and back fins toe-in: 3/16"
Just for the cant angle I would like to have your point of view.
For the front fins I wanted to put 4 cant angle and for the back fins 2 degrees cant angle. What do you think?

IMHO…
Quad set up front @ 11 3/4" tail to rear dot and 1 1/8" in from rail 1/4" toe 6 degree cant. Rears @ 7", 2 1/4" in 3/16 toe 4 degree cant.

Break free of Mckee…

Hi mattwho,
Thanks so much for your answer. Do you apply these measurements for any kind of board length or this is specific for my 5’0 ?

4 & 2 is fine for a more drivey board; try 6 & 4 for a more ‘normal’ response and 8 & 4 or 8 & 6 for more lift and maneuverability.
