 Fish are caught for recreational purposes from boats which range from dugout canoes, kayaks, rafts, pontoon boats and small dinghies to runabouts, cabin cruisers and cruising yachts to large, hi-tech and luxurious big game rigs.Larger boats, purpose-built with recreational fishing in mind, usually have large, open cockpits at the stern, designed for convenient fishing.Big game fishing started as a sport after the invention of the motorized boat.
