Frequently asked questions
What tool do I need?
A Torx T40 key, such as the Sonar T40 or the North multi-tool. North recommends not using power tools to assemble the foil.
Do the screws need greasing?
Yes. North recommends putting a little Sonar marine grease on the thread and under the head of each screw every time you assemble the foil, with everything clean of sand.
