Families are invited to explore life at sea through hands-on activities at the Mattapoisett Historical Society, 5 Church St., on Wednesday, Aug. 6 at 1 p.m. Send a message with signal flags, sample hardtack, learn basic sailors’ knots and personalize a ditty bag (used by sailors to store personal items and small tools and equipment.) The program is free, but donations are welcome.

For more information, call 508-758-2844 or email mattapoisett.museum@verizon.net.
