Captain is a rescue lifeboat from The Island of Sodor.
Captain is an energetic lifeboat assisting with work on the Crotoonian Coast. Working alongside Foduck, he makes sure to look out for anyone in need out at sea and is always ready for action! He may get on Foduck's nerves at times with his energy, but he's a dedicated rescuer, and the two rescue boats make an excellent team!
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 The class lasted in service until 1982, when "The Chieftain" was withdrawn from Barmouth Lifeboat Station.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.
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.
