The Port of Keyport is a marina that has a boat launch ramp, 14 private slips, and five 50-foot slips for guests. All slips have electric power and water. There is a long waiting list for the Port of Keyport's private slips. Guests can moor in the Port of Keyport for up to six hours without charge. Slip rental is $10 per day for boats under 7.6 meters (25 feet) and $15 per day for larger boats.
The Port of Keyport is within easy walking distance of the Naval Undersea Museum and all of the village's businesses (a general store, auto repair shop, a post office, restaurants, and a bed and breakfast).
The Commissioners for the Port of Keyport meet the first Monday of every month at the Marina office.
