Used to always do it when I had boats in the West end of the Sound. Always stopped to help out a boat in distress. Mostly it was some yahoo who had run out of fuel but there were groundings and once, after a bad squal, a dis-masting. Always told them to do the same when they saw someone else stuck. Even if they offered to pay me.
Once however, I did accept a pair of nice "bugs" from a lobsterman who had his line in his prop.
