The ultimate way to adjust your mast position while in the water with NO TOOLS necessary. Whether you’re a wake foiler looking to make quick adjustments to your mast positions as riders switch out, or you’re a prone foil surfer looking to get the perfect amount of lift on take off, or if you’re a wing foiler dialing in your setup for the days conditions….These thumbs screws are for you. Just flip your board over and adjust your mast position IN THE WATER as you see fit.

We’ve tested them in the lake and ocean. You will see some erosion to the finish in the saltwater but other than that, these screws are KILLER. A must have for any semi-serious foiler.
