I'd second Nick #2's suggestion about Clinton and pass it by. If you want to make it a bit of a longer trip on day #2, heading up the Connecticut River to Old Saybrook (via North Cove) or Essex (right on the river a few miles past I-95) might be other spots to consider. Keep an eye on the tides, though, (especially if your heading all the way up to Essex) since it may cost you 2 or 3 knots of headway at max ebb.
Note that North Cove can get somewhat shallow at low tide although I keep hearing their going to dredge in there (don't know if its happened yet or not).
Have a great trip!
