How Do I Put the Foil Into the Tuttle Box?
- Stand on the bottom of your board while wearing socks or barefoot, be careful to not scratch up your board, and stand one foot just in front of the Tuttle box.
- Place Tuttle head into the tuttle box evenly and start rocking the mast/strut forward and backward while putting steady pressure down onto the board. Grab onto the Fuselage of the foil while doing this. The steady rocking back and forth will slowly seat the tuttle base into the box.
- Lean board over to put in the bolts and tighten them.
- Turn board back upside down again and retry rocking and pushing mast into the board again to get rid of any looseness. Re-tighten bolts again. repeat until you are satisfied the Tuttle base is as tight as possible.
DO NOT hit the foil base into the board with a Rubber Mallet or anything else.
If you cannot get the Tuttle Base into the Tuttle Box, sand the sides of the Tuttle base not the Tuttle box until she fits inside the box. Easiest to do this with a sander. Check video below for sanding the base.
Rough Guidelines to Tuttle box placements for different length boards: The measurement is made from the back opening of the Tuttle box or from the trailing edge of Mast on our plate foil to the tail of the board.

Prone surfboards in general need the box further back than a SUP. This is because the lighter the board, the less lift you need to make and/or keep it foiling.
Think of your back foot on a prone board where you would like to place it when standing up into surf position. Generally, your foot will be close to standing directly on top of the mast when on a prone board or slightly forward of that position.
On a SUP, you can stand slightly aft of the prone position, so many stand on the trailing edge of the mast on their SUPs.
Box placement further forward creates greater lift and earlier planing but you will be standing further towards the nose to balance it.
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.
Tuttle Box Holes Template
Download and print this template to help you drill the holes for attaching the foil to the Tuttle box in the correct place on the deck of your board . Make sure the scale is set at 100% before printing, then check measurements to see if the scale is correct after you print it. The holes are 105mm apart, measure that on your template to confirm sizing of template is correct.
