Newport/Martha's Vineyard/Nantucket--your feedbacked needed!
Actually it looks like leaving Cuttyhunk at slack high tide puts you into Buzzard Bay at the very end of the ebb. If you cross into Vineyard Sound Soon you can catch the flood there for a good 3 hours. Hopefully I'm reading this right. I used June 20 as a test case. So what's the best safest cut into vineyard sound?
