With its picturesque waterfront park and a rich tapestry of history, Boston Harbor offers a captivating blend of romance and adventure.

A cornerstone of American history since the Boston Tea Party in 1773, Boston Harbor serves as both a gateway to the city and a vibrant estuary of Massachusetts Bay.

Curious about tide clocks? These fascinating devices track the lunar day—24 hours and 50 minutes—reflecting the moon's powerful influence on Earth’s tides. Since there are two high tides each lunar day, tide clocks complete a rotation every 12 hours and 25 minutes. Quartz tide clocks are ideal for the predictable tides of the Eastern United States and can be easily set using local high tide times found online or adjusted monthly during a full or new moon.
