Abstract
A laterally unstable small water craft such as a sailboard, a kayak, a canoe, a sailfish, a sunfish, or the like is provided with laterally extending narrow stabilizing wings of relatively shallow vertical dimension that limit tilting of the craft. Preferably the wings are provided with mounts that permit independent adjustment of the wing rake angle, dihedral angle and angle of attack, and the wings may be folded to positions entirely between the longitudinal sides of the craft. Conveniently the wings and their mounts are provided as a kit for attachment to any particular type of small water craft.
