Went to Keystone - keyport marina a few weeks ago to take my nephew. Lady was walking off dock at 6pm. Said it was only open Fri-Sat-Sun 8am-6pm I hadn't been there in years. But when I was a kid 20 years ago my dad used to take me all over the state to heated 24x7 docks. Looks like that is a thing of the past. There was another dock on Keystone called peir 51 but she said it was closed.
