We are not affiliated with Cedar Island Marina. We are an independent mobile detailer that services boats kept there.

Cedar Island Marina sits on the Hammonasset River in Clinton Harbor, tucked between a quiet residential area and the Hammonasset nature preserve, deliberately clear of industrial and commercial traffic. It has been family owned and operated for nearly forty-five years and runs 400 slips for seasonal and transient boats.

Marinas.com has named it an Elite Marina for seven consecutive years, a designation given to a fraction of a percent of marinas nationally. The site includes a heated pool, fitness centre, waterfront restaurant, captains' lounge, and full-time security, and in 1996 the EPA cited it as one of the twenty-five most environmentally conscious marinas in the country.

Preserve water is productive water. Growth at the waterline comes on faster here through midsummer than in a busier, better-flushed commercial harbour, and on a larger boat that is a lot of linear feet to correct if it gets ahead of you.

The Hammonasset also carries silt and organic material down into the harbour, so the stain runs browner than a pure salt-water boat's. We budget extra time at the waterline on Cedar Island boats, and at 400 slips this is a marina where booking alongside your dock neighbours makes the forty-minute run from Milford work well for everyone.
