A recent demo is indicative of the J/70s performance envelope around the track. Starting in just 4-6 kt breezes building to no more than 8-13 kt winds-- the J/70 averaged 6.7 knots over an 8.96 nm track that took 1 hr 19 min 46 secs. Top speed was 10.8 kts downwind while average speed upwind ranged from 5.8 to 6.5 kts-- pretty quick for a 23 footer! In short, we sailed 4.5 nm upwind, turned around, set the chute and sailed 4.5 nm downwind. The track can be seen here on Phillipe Kahn's MotionX-GPS software (Phillipe's a fellow J/100 owner in Santa Cruz, CA)- http://bit.ly/H06lmO. For more J/70 Speedster sailing information
