Welcome aboard EC!
Realize that SailNet has members from all over the world. The Pelagic Sailing Club, which is based in the Boston area, was designed to bring boat owners and competent crew together. You might want to check it out. Here is a link to more info on them.
Also, Yahoo Groups features a Mass Bay Sailors group that, thanks to the efforts of Bill Scanlon, is very active. Here is a link to MassBaySailors.
You would be surprised at the number of boat owners in the area that don't take their boats out for want of crew.
