Does anyone know of some good places to dock for a few hours in Boston?

Boston Yacht Haven it is right next to the Marriot Long Wharf. When your there by boat call on channel 9 and you can ask them if they have any slips. $15 per hour and you have to be out by 10:00pm or pay an overnight charge.

I would sometimes leave my boat at Columbus Park, also next to the Mariott but I wouldn't leave it for long, oh yeh, a higher tide helped greatly....

The docks in back of the Barking Crab allow you to tie up for free, just pretend like your going to have a couple cocktails inside. In fact, there's no one really there even checking on things.

Wow, I thought parking in Boston was expensive. I think I will try the Don's suggestion if I can figure out how to get there. Thanks for the info.

Just south east of the Boston Waterfron Hotel - think Fore Point Channel...
