Lake Winnipesaukee - US Mailboat M/V Sophie C

US Mailboat M/V Sophie C

The M/V Sophie C is the oldest, and one of only two currently operating, floating United States Postal Service post offices. Floating post office service was started on Lake Winnipesaukee in 1892, and currently delivers mail daily to eight of the lake's islands between June and September. As a floating post office, 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 used to sell ice cream and snacks to residents of the islands she serves.
