In this whimsical tide clock the lobster boat is beached on a giant lobster at low tide. I'm not sure if this is good news or bad news for this lobsterman, but he'll certainly have a helluva story when he gets back to the dock! The Lobster Boat tide clock can be set to follow most semidiurnal local tides. The tide moves in the picture! Precision tide movement with mechanically animated display, measuring 11" high x 6.5" wide x 2 "deep.
