saw a large percentage of people towing dinghies in New England down to the Carolinas. A lot less of it in the Great Lakes, Canadian Maritimes, and the Bahamas. Almost never on the west coast. Probably has to do with the availability of harbors close by to run for in the case of worsening weather? In New England you never seem to be more than about 20 miles from shelter; west coast, could be 700 miles.
