Just went sailing out of Hyannis this past weekend. 15-18 knots on Saturday and 12-15 on Sunday... beautiful sailing conditions!
However, just an FYI.. the water is colder than it should be this time of year becaue of Irene. Water temps are in the high 60's to around 70 even. Normally they should be upper 70's.
It was in the mid 60's sailing this past weekend and mid 70's today so it could be anywhere temperature wise.
Bring your warm gear just incase! And shameless plug, I will have Zhik, Ronstan, Gill and etc on site incase you don't own any warm gear.
