Most of the features of the classic sport fisherman were gradually developed in the 1920s and 1930s as existing motor cruisers and commercial fishing vessels were adapted for fishing with outriggers, fighting chairs and other ancillaries such as bait boxes and flybridge helm stations. These boats, though crude by modern standards, scored many pioneering big game catches of huge bluefin tuna, broadbill swordfish and marlin. Through the 1930s and 1940s sportfishermen in Florida, amongst them John Rybovich and Ernest Hemingway, continued to innovate and refine, and in 1946 the Rybovich yard launched the Miss Chevy II, a 34-footer that crystallized all the innovations that had gone before into a design whose features - raised foredeck, flybridge controls and roomy cockpit - are still closely followed by today's leading sportfish builders. The need for greater range and speed as anglers sought gamefish further and further offshore resulted in the development of bigger boats powered by larger engines, but the basic layout of a dedicated big game fishing vessel has remained largely the same since the late 1940s.
