Abstract: A boat seat which effectively positions a person for paddling a boat such as a canoe or kayak includes an upper platform for supporting the posterior of the person and a lower platform for supporting the knees and shins of the person. The upper platform near its rear end is pivotally connected between the two frames on a substantially radial component of each frame near a rear pivot end thereof. The boat seat includes a device for adjustably stopping the downward pivotal movement of the upper platform front end at a position selected from a plurality of positions along a vertical component of each frame. The lower platform includes a back end which can rest on the boat floor. A front end of the lower platform is adjustably connected between two substantially horizontal brackets which are each affixed to one side in spaced opposition to each other.
