For visiting boats
DiMillo's Old Port Marina sits on Long Wharf in the middle of Portland's Old Port, a two-minute walk from dozens of restaurants and provisioning, and calls itself the only major transient dock in Portland. Its 130 floating slips take sail and power boats up to 250 ft LOA with up to 30 ft of water, open to guests all year. There is a 24/7 fuel dock with high-speed gas and diesel hoses, shore power to 100 A, Wi-Fi, heads and showers, laundry, pump-out, waste-oil disposal, a ship's store and the DiMillo's floating restaurant. Rates are per foot per night by length band and season (flat rates for boats 35 ft and under); the office works on VHF 9 and 71.
