Correction, the RAVE, made by WindRider looks like it is either back or still in production. I actually think production stopped for a while due to instability or change in ownership in the campany but RAVE stock at dealers never ran out.
Manufacturer claims boat foils at 1.75x windspeed.
Mfg. claims liftoff at 7-8 knots of wind with 30 - 50 kg payload (the skipper). Sort of rules me out lifitng off at 8 knots in a RAVE.
I lift off at 10 to 11 knots wind speed in the trifoiler. Trifoilers sailed by Greg and Dan K. beat the RAVEs at SF Speed Sailin in June 2006
