"A beautiful sea" reads the first title, following by wave after wave that seems about to swamp the ship. Four minutes later, we are informed there is a storm, and it looks even worse.
Joe Rosenthal's documentary does not seem to survive in full; there are reports of the ship setting out from harbor at the start that the copy I looked at lacks. Still, it's a picture of the hard and harrowing work that fishermen undergo.
Rosenthal started out as a cameraman about 1900, and usually worked in documentaries through his last credit as a camera operator in 1935. He died in 1946. 87 or 88 years old.
