Boat column rule: in the water at a 65°F high and 45°F low or warmer; launch or haul-out from a 52°F high; laid up below.
By that rule a boat at Baltimore has 6 months in the water (May to October), 3 of launch or haul-out and 3 laid up. By that rule a boat at Salisbury has 6 months in the water (May to October), 3 of launch or haul-out and 3 laid up.
Maryland freezes in short spells: Baltimore has about 93.2 freezing nights but only 10.7 days that stay below 32°F, and those overnight freezes are what crack a boat that was not drained.

3 at Baltimore (November to April) and 3 at Salisbury (November to April), plus 3 and 3 months of launch or haul-out. Those laid up months hold 16.4 of the 19.3 inches of snow Baltimore averages a year (85%), which is the load on a cover or carport roof. At Baltimore a boat is in the water from May to October (6 months), against 6 at Salisbury.
