The Lake Buccaneer is an American four-seat, light amphibious aircraft derived from the Colonial C-2 Skimmer, itself a development of the three-seat Colonial C-1 Skimmer.
The Colonial Aircraft of Sanford, Maine developed the C-2 Skimmer in the 1950s as a four-seat variant of the earlier three-seat C-1 Skimmer. The name was changed to Lake in 1959, along with some design improvements. Produced until 1970, this version was designated as the Lake LA-4 Amphibian.
From 1969-1972 the company sold some LA-4s modified under a Supplemental Type Certificate as flying boats, without landing gear, but with removable beaching wheels, under the name Lake LA-4S Seaplane.
In 1970 a fuel injected Lycoming IO-360 engine was fitted and the resulting aircraft was named the Buccaneer. This model replaced both the LA-4 and Seaplane in production and has a higher cruise speed as well as increased gross weight. Fuel tanks were also added to the wing pontoons, with per side, taking fuel capacity from to .
A six-seat development in 1982, with a lengthened hull was named Renegade, this had either a or a turbocharged engine. A military version was called the Seawolf.
The LA-4 is a cantilever, shoulder-wing monoplane amphibian with a single-step all-metal hull with retractable tricycle landing gear. It is powered by an Lycoming O-360 piston engine in pusher configuration, pylon-mounted above the hull.
