Hiya, I sailed to the vineyard this summer for the first time but from Shelter Island NY. The conditions were fine past Block but windows will vary. I use Pocket Grib on my iPhone
direction and speed (along with other sources) and iNavX
on my iPad
which is really great. It or something like it along with reading any guides should help through areas like Watch Hill. Also a big consideration is the Race
which is the current
in and out of the Sound and Narraganset bay. Highly recommend a copy of The Eldrige for tide and current
information. Check out Cuttyhunk if have a chance and like low key, out of the way places.
