masts, fuses, front foils and stabilisers (credit: Admin)
beginners start with a big front foil and stabiliser
the classic curved delta shapes shown in the photo above are stable and forgiving
faster foils are thinner (e.g. 11mm) and have a higher aspect ratio (span / chord)
the thicker delta foils can be muscled on to foil by ollie-ing them up
thinner, high aspect foils need higher take off speed and a gentle, higher cadence pump action
if you pump too aggressively on a high aspect foil you can crush the pump
to keep the foil efficient, scratches can be polished out using 600 grit ‘wet and dry’ paper – use wet to reduce the chance of breathing in carbon fibres

to prevent permanent bonding, aluminium masts and fuses need regular flushing with fresh water via loosening the screws or dismantling to prevent corrosion /fizzing from salt water
winglets on the foil ends provide stability and may turn up or down depending on design
the rear stabiliser is angled down to provide more lift to the front foil, and drag for stability
shims between the fuse and the stabiliser reduce the down angle and the amount of drag
changing the stabiliser can have a huge impact on the dynamics of the foil
