A Bimini top is an open-front canvas top for the cockpit of a boat or Jeep, usually supported by a metal frame. Most Biminis can be collapsed when not in use, and raised again if shade or shelter from rain is desired. Bimini tops differ from dodgers in that dodgers include protection in front and on the sides, while a Bimini does not. The Bimini is used mostly as protection from the sun; it offers no protection from wind, rain, or spray when moving forward at any speed. Rain protection is only given if the boat is stationary and there is not any wind.
The Bimini top was invented by Paul Johnson and his company, Johnson's Marine Cushion and Canvas in Warren, Rhode Island.
