On catamarans a single main foil can be attached between the hulls just in front of the center of gravity and at 2 degrees of incidence spanning the tunnel with supporting struts.

How do foiling catamarans work. All data recorded from the boats is. The 4 T-Foils do not have to be operated by the sailor during sailing. The style of the foiling AC75 has never been seen before in sailing.

The foils are cured in our own Autoclave. The front wing is pulled upwards as it moves forward as the water molecules passing over the top surface of the front wing accelerate to catch up with the water molecules passing over the bottom surface which is shorter because it is flat. The operating principle of a foil surfing is a matter of fluid dynamics.

Heres a pic of the underside of the one that capsized. Under the AC75 concept the whole hull will lift clear of the water supported by two or three of the foils. Our winning foil design was created in close cooperation with Glenn Ashby and the designers of AC Team New Zealand.

The F50 catamaran is a revolutionary concept in sail racing that is the culmination of 10 years of development in high-performance foiling multihull racing. Sailing close to the wind a catamaran does not allow for sailing close to the wind as much as a monohull. A new fleet of foilers whose hulls hover in the air lets even amateur.

Average skilled dinghy or catamaran sailors with some trapeze experience can safely foil with the iFLY15 after only a few hours. In the hand of an experienced sailor iFLY15 offers a. Multihull sailboats can also employ hydrofoils only to assist performance.

However a work-around is to sail on reach. Catamarans sail faster in the reaching position. The closest are the IMOCA60s but they are only using the DSS style foils to reduce hull drag and increase speed.
