Isles of Shoals Chart

When approaching the Isles from the north, be careful of the unmarked rocks surrounding Duck Island. From seaward, steer clear of Anderson Ledge, which is buoyed and marked by a post. Just to the north, and off the direct course, lies unmarked Cedar Ledge. Otherwise, major hazards to navigation are well marked, and the lighthouse on White Island is easy to see. However, always be prepared for fog, which is common here all season.

Dockage, Moorings and Service:

There are no marine facilities in the Isles of Shoals, so be sure you have plenty of fuel to get home if you arrive by powerboat. The moorings in Gosport Harbor belong to mainland yacht clubs. Visitors may pick up an open mooring, but should be ready to leave immediately if the owner returns. If you dinghy to the beach or to one of the fixed jetties, be aware that the tidal range is just under 10 feet during spring tides (tides are only 2 minutes off Portland, Maine). Currents are weak in the anchorage, but can be fairly strong in the cuts between islands.


The anchorage in Gosport Harbor is deep (20 to 30 feet), but of poor holding ground. It is best to try and get a mooring for the day if possible.


No harbormaster available. Contact the New Hampshire Director of Ports (603-436-8500).
