J/70 Speedster Performance Update

J/70 speedster- sailing with spinnaker fast (Newport, RI)- After another week of sailing the new "baby J", it's pretty clear the performance is exceeding all expectations.  A fun boat, indeed, the J/70 Speedster is.  Teams from North Sails and Quantum Sails have had a chance to sail them in a wide range of wind conditions, from 3-5 kts up to 25-28 knots.  J/70 handles the wide-range of conditions with ease, far greater ease than many had imagined.  Team Quantum has reported sustained bursts up to 15.8 knots on their GPS trackers in just 17-18 kts of wind, read more about that experience here- Norm Davant's "Early Adopter" report on SA.

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.
