Lake Winnipesaukee, NH also has the distinction of hosting the oldest, and one of only two currently operating, floating United States Postal Service vessels in the U.S.– the Motor Vessel (M/V) Sophie C. Floating post office service was started in 1892 and the Sophie C currently delivers mail daily to 8 of the lake’s islands between June and September.

 As a floating post office, the Sophie C delivers mail Monday-Saturday, sells postage, and collects and postmarks outgoing mail. Sophie C also operates as a sightseeing boat, carrying up to 125 people on her two cruises a day as she delivers mail, and sells ice cream and snacks to residents & summer camps of the islands she serves. Passengers aboard the Sophie C. are invited to fill out M/V Sophie C. postcards and mail them while on board. Sophie’s own unique, collectible cancellation stamp make for good topic of discussion with post card recipients!

Morning Mail Stops: Loon Island, Bear Island, 3 Mile Island, East Bear Island

Afternoon Mail Stops: Camp Lawrence, Birch Island, Sandy Island, Cow Island, Jolly Island.
