Norton's is fine and its a short walk downtown or towards some nice restaurants past the East Greenwich Yacht Club. Brewers is fine as well. The problem with Brewers and what used to be Greenwich Bay Marina Club was the railroad bridge. You could not get a boat under it so if you hauled there, you stayed there.
Stay away (repeat away) from Warwick Cove. It always seems to be loaded with 32' Silverton's that take delight in powering full speed in narrow channels and breaking every rule
of seamanship possible. The 3 minutes closer to the airport doesn't make up for the risk of danger
to your boat at the dock
, in the channel or on the hard
And before anyone asks, I spent 10 years in Greenwich Bay. I'm not one to generalize, but Warwick Cove was just plain dangerous.
