Tuttle Box Placement

Rough Guidelines to Tuttle box placements for different length boards.
The measurement is made from the back opening of the Tuttle box to the tail of the board.

Board Length in inches Distance from tail of board in inches
5’0″ to 5’9″ 8” – 12”
5’10” to 6’6” 10”- 15”
6’7” to 7’4” 16”-20”
7’5” to 8’6” 18” -22”
8’7” to 9’6” 23” to 28”

Box placement further forward creates greater lift and earlier planing.

Box further back usually helps the boards turn ability.

Lightweight riders need less lift and heavy riders need more lift so consider the riders size when choosing box placement.
