RV & Boat Storage in Portland, ME

Portland local guide

Portland boats run on Casco Bay, the island-dotted bay off the city's waterfront, while inland trips head to Sebago Lake and the lakes northwest of town. The storage here follows the coast: Maine Yacht Center is in Portland itself on Kensington Street, Devon Self Storage is just north in Falmouth near the Falmouth Spur and I-95, and Yankee Marina sits up the coast in Yarmouth on the protected west bank of the Royal River.

Maine winters decide the storage choice. Maine Yacht Center has 60,000 square feet of heated inside storage, which lets its crew work on stored boats all winter, and Yankee Marina offers both cold outside storage and heated inside space for more than 200 boats, though its storage was wait-listed when we checked. For owners who trailer, Devon Self Storage rents outdoor parking for boats and RVs month to month.

Boating in Maine: boats are registered through the Department of Inland Fisheries and Wildlife, and motorized boats used on inland waters must also display a Lake and River Protection sticker, which comes with a Maine registration. Ramps and dump stations below come from OpenStreetMap.
