A ketch is a two-masted sailboat whose mainmast is taller than the mizzen mast (or aft-mast), generally 40-foot or bigger. The name ketch is derived from catch. The ketch's main mast is usually stepped in the same position as a sloop.
Irene is a 100-foot ketch built in Bridgwater in 1907, the last ship built in the docks and the only ketch built in the West Country still sailing. It was built by FJ Carver and Son and launched in May 1907. The Blake Museum in Bridgwater opened an exhibit about the ship in 2010.
