Near a beacon at the end of one jetty, two men with long poles wait to help a fishing-boat which is running under full sail for the harbour. Two other boats ride at anchor near the jetty, to the right. Dark cloudy sky. A " magnificent picture " (Sm.). Canvas, 37 inches by 51 inches.

This scene is very similar to other paintings Ruisdael made in this period and these often served as inspiration for later painters of seascape.
