I plan to be in Nantucket August for a week, but dont know when yet. As of now, i can plan a dive or three in the area Sunday the 4th, unless that is your travel day, or 24 rest after flight. I do have a night planned not far from wells (Gun Rock in Hull MA). It is a guided shore dive done by mass diving out od Natick MA.
May be able to take some time off work if you have an irresistable dive plan, like wreck diving etc.
