Description
The Duotone Foil Assist AL Set, a system that gives you an extra boost exactly when you need it.
Built from lightweight aluminium, measuring 84cm, the eMast AL is incredibly stiff and provides a direct feel.
The motor pod is fully integrated into the mast and positioned behind the leading edge (17cm below top plate), minimising drag even during touchdowns, featuring the two-blade folding propeller that further eliminates drag for effortless glide on waves.
The eMast mounts to your board like a conventional foil mast.
A fuselage adapter is required to mount a fuselage onto the eMast, luckily Duotone offer 10 different adapter fuselage options so whatever brand foil you have will be compatible.
The Foil Assist is powered by two compact batteries housed in a waterproof box mounted on a lightweight eHarness (3.76kg). Keeping your board free from extra weight and drag.
