Abstract
An open-trough kayak sailing accessory kit is described in which a removable, portable, lightweight bi-pod mast is mounted to a removable board/hatch at the front of the kayak. The mast then tilts back over the kayak so as to center the sail over the craft. The bi-pod mast is hinged to the board and has various rope securement points to give it fore and aft stabilization. To provide lateral stability to the kayak, a leeboard kit according to the invention is included, having a leeboard removably affixed to the side of the cockpit of the open-trough kayak where no cross bars or flat top surfaces for attachment are otherwise present. A slide clamp is employed which fits the side of the open cockpit, in allowing the leeboard to rotate about the clamp, permitting a user to raise and lower it into the water as needed. By employing the two kits together, an open-trough kayak can easily be utilized for ocean sailing, otherwise quite difficult to do.
