- “Full steam ahead!”
- ―Captain's catchphrase
Captain is a brave motorised lifeboat. He is part of the Search and Rescue Team.
When Thomas got lost on Misty Island, he helped in the search for him by taking the Fat Controller to search by sea, and later brought Jobi logs for the construction of the Sodor Search and Rescue Centre.
When Stephen went missing, Captain, along with the rest of the Search and Rescue Team, went to look for him.
In the nineteenth season, Captain was eager to assist in the rescues of Henry and, later, Rocky, but was unable to assist due to the accidents occurring far from the water. He, along with the rest of the Search and Rescue Team, then responded to an emergency at Brendam Docks.
In the twentieth season, he, along with Harold, were called upon to find the Fat Controller and Skiff, after the rail boat went off to sea without his captain in search of a mermaid. They found the two on a small beach near Bluff's Cove, where Captain rescued them and then escorted them back to Arlesburgh Harbour.
Captain is a lifeboat who resides at the Sodor Search and Rescue Centre in his own small shed, ready, willing, and always on hand raring for action in case of an emergency. He can easily be dispatched from his shed by means of a slipway, but often resides in the small dock at the Search and Rescue Centre too. Being a lifeboat, Captain knows that duty may call out at sea to help and rescue anyone at any time. He takes this role seriously and is highly assertive, confident, and is unfazed in the face of daring, dangerous missions, but is not made ostentatious or egotistical by his important responsibilities. He is level-headed, always knows what has to be done, and shows good leadership skills.
Captain is based on an ex-Royal National Lifeboat Institution twin engined Liverpool-class Lifeboat. These originated in 1931 as a single engine design, with the twin engined version being built from 1945 to 1954. The class lasted in service until 1982, when "The Chieftain" was withdrawn from Barmouth Lifeboat Station. Unlike most Liverpools, which were carriage launched, Captain is launched from a slipway. Numerous examples of this class are preserved.
Captain's cab is painted yellow, his sides are blue, and his hull is red. He is lined in white. He has a long, thin, yellow mast at the stern of his body.
