Old Port Launch at Block Island is $3 pp/pt. Maybe they have a new launch they're trying to pay for? 14 years ago I stayed at the town dock in Bar Harbor - $1/ft. I hope this isn't a sign of the 'new' Maine.
Locally, Sag Harbor seems to have reached the price limit. As I sail past there on the way to West Neck, I notice large power boats anchored outside the breakwater. Perhaps they feel it's less painful to put the tender in the water than to pay the dockage.
