U.S. Mailboat Cruises

The oldest floating post office in the country

Mailboat cruises will begin on June 21, 2021. For cruises on the Sophie C. earlier than June 21, please view scenic tours.

The U.S. Mailboat navigates smaller channels and waterways to provide postal service to the island residents of Lake Winnipesaukee. On each trip she'll visit a number of different islands, and the Skipper will point out areas of interest along the way.

Passengers aboard the Mailboat are also invited to fill out postcards and mail them right on board, complete with a unique, collectible cancellation stamp!
