Windsurfing foils add a very exciting improvement to the traditional windsurfing fins. Foil Windsurfing can be divided into many categories. The biggest one is the free ride group. Easy mid sized foil wings and longer fuselages really flatten the learning curve.
Slingshot Fwind windsurfing package has been a favorite for years. It has a 76 cm wide front wing and very refined foil shape to get you up on the foil, then keeps you from breaching when you get near the surface. The set up is pretty durable. The nice glide really helps learn your Jibes.
Starboard Super Cruiser is rated as their easiest to learn on windsurfing foil. With the large front foil wing and adjustable tail stabilizer, 8 to 10 knot foiling is possible with mid sized sails. Very light weight carbon wings really helps the foil wing setup to lose a couple pounds.
