Armin Hansen's Decoration led a sale of American art at Christie's New York on September 22.
The lot realised $509,000 against a valuation of $350,000 - an increase of 45.4% and a new record for Hansen's work.
His previous record stood at $390,000 for First Feel of Leather, at Bonhams in 2008.
The auction house explains: "Decoration is a visual celebration of the seafaring life the artist so loved.
"He paints a typical day on the dock as sailors and deck hands chat while, perhaps, repairing and readying rigging and sails for approaching voyages.
"From the piers and docks and wharves, and from the sand beaches and rocky covers Hansen viewed men and their struggle with the sea from countless angles, continuously refining his material over the years, exhibiting up and down the West Coast and occasionally in New York."
Childe Hassam's The Audition, East Hampton also achieved an impressive result. It realised $227,000 - up 26.1% on its $180,000 estimate.
Hassam was a key American impressionist. President Barack Obama chose his 1917 painting, The Avenue in the Rain, for display in the Oval Office.
