A local in South Dartmouth said that some of the moorings had been hastily added in New Bedford in anticipation of the storm. The person suggested that they weren't that heavy and weren't the helical anchor type. I don't know if it is true.
Our boat fared well on the "hard". It was finally pulled at 8:00 PM on Saturday. We spent most of the day without power in a B&B. Our boat was at South Wharf in South Dartmouth, MA -- and our B&B was in NORTH Dartmouth. :^) The gusts were supposedly over 60 knots at the marina at points; and the sustained winds were over 40 knots most of the day. A couple of boats came loose in the Padanarem mooring field. We saw a large, full keeled sloop on its side on-top of the rocks on the opposite side of the mooring field. The New Bedford Yacht Club emptied-out everything. The South Wharf had four boats in the water -- all pretty small that did okay in their sheltered area. A boat on a mooring field there would have been a very iffy situation. They used helical anchors after Hurricane Bob -- so the likelihood is that the mooring ball would stay where it was supposed to. However, the strain and stress on the boat and lines would have been pretty rough. I supposed we could have survived it; however, if the storm had been closer to where had been predicted (closer to Hartford, CT or Newport, RI, then it would have been foolish.
I think that the floating docks that were sheltered in New Bedford where fine; however, the had 2-3' choppy seas in the Harbor. If you have an 80' steel fishing trawler, maybe it would be fine to sit-out a hurricane...otherwise, I think it would pretty iffy (at best). We saw only tropical storm force winds; and, not what was possible.
Regardless of the misery that this storm has caused to many, many people. It could, and might, have been a lot worse. The storm stretched from edge of Nova Scotia to Lake Ontario after it was largely disipaated. Thank our lucky stars that's its force was reduced when it finally made landfall on Long Island.
