Pathe pictorial goes to sea

Waves breaking in the sea. Old ships; cadets in training on sailing ships. Knot tying. Schooling on a trawler at Grimbsy. Throwing nets. Fishing boats and nets a shore. Old seaman finding a bottle with a message from a ship-wrecked man to his wife - he goes to the city and looks for her (shown as an incongruous figure out of place in the city). Finds only ruins.
