A lobster boat is biding its time while waiting for the tide to rise high enough to allow it to enter the raised harbour, the entrance which is marked by that tower and wall of rocks.
This is along the Bay of Fundy, and you can see the high tide mark by the black on the pile of rocks that help shelter the harbour. They don't have to wait until full high tide.
