Check out Spectacle Island in Boston Harbor if you've never been there. Google it and you'll find a link to all the Islands but Spectacle has slips and moorings available and some great hiking trails. The fee is $1.50 a foot I think for a slip. Other wise check Braces Cove in Gloucester; I'm pretty sure there is enough depth and it is a nice protected cove. We've taken our 30 Sabre there with a 5 foot draft plenty of times for over-nighters from Manchester. Hope this helps and have fun!
