The steam ship Indomitable is shown from the port broadside in a calm sea. She is under steam power, with smoke streaming from her funnel, but all sails, except the main and mizzen lower courses over the funnel, are hoisted. She is flying the British flag at her stern and a company flag at the main mast. Figures can be seen on the deck. Seagulls skim over the waves in the foreground while other sailing craft and a distant, low lying shore, are visible on the horizon.
