Tubular-class lifeboat
Updated: Wikipedia source
Tubular lifeboats were effectively a type of catamaran, or raft, with a flat deck mounted between two buoyant tubes. The decks of the boats were approximately 11 inches (280 mm) above the water. The lifeboat was the design of Messrs. Richardson, of Bala, Merionethshire. The boats were usually 12, 14 or 16-oared, with sails available for suitable conditions. A tubular lifeboat was first placed in service at Rhyl in 1856 by the Royal National Lifeboat Institution (RNLI). Even though just six more of this type were constructed for the Institution, tubular lifeboats were in service with the RNLI for a combined period of 83 years. They operated primarily at just two stations, Rhyl and New Brighton.
