F. History of Foilcats


The Foilcat “Kangalope” is a Hobie 18 fitted with surface-piercing foils, has been tested extensively in Florida since late 1997. It has been sailed on the foils 50 different days, in North Florida, off the beach at Daytona, at Ft.Lauderdale and Miami, even at Rick’s Place in the Keys. The Foilcat “Jackalope”, built on a Hobie 16, was first in the water at the Miami Boatshow in February 1999, and has been out foiling ever since.  This foiling was great fun, as can be seen from the photos at Lake Santa Fe in North Florida, but it was also directed at improvement of speed and behavior of the rig.

We are currently working on modifying the major aluminum lifting foil shape, to replace the Clark-Y flat bottomed lifting foil currently in use. We anticipate that this may lead to a commercial product with better behavior.What is sailing a Foilcat like?– Like getting a thoroughbred racehorse galloping at top speed- a tall horse way off the ground going way fast!  Normal beach cats are fast too- but now they feel more like small, short-legged ponies! These Foilcats need 11 knots to climb up out of the water and fly BOTH hulls. They need wind of sustained 13 knots to foil continuously. Technically, the realistic goal is something like 1.5 times windspeed for this and all other foiling boats. In a breeze, it surely felt like 28+ knots (31+ miles per hour) to me, based on many years of water skiing!

One big advantage of surface-piercing foils is that when foiling, the boat does not crash and then pitchpole like T-foilers sometimes do. With loss of wind at speed, these surface-piercing foilers just settle back into the water at about ten MPH and then immediately pick up to full speed when the wind returns.
