ABSTRACT:
A retractable step or ladder is mounted to the rear of the personal watercraft. The retractable step has a pair of hollow channel members fixedly mounted underneath the riding platform. An elongated rigid member is mounted to each channel member by springs which permit substantially horizontal travel of each elongated member relative to the channel member until a stop is reached. The springs bias each elongated member into positions where the elongated members are not extended relative to the channel members, however the biasing force of the springs can be overcome by moderate effort of the user of the watercraft who wishes to climb aboard the watercraft from the water. Camming surfaces are formed substantially at the end of each channel member and at the end of each elongated member, and the camming surfaces mate and allow a downward pivoting motion of the elongated members about a hinge pin only when the elongated members are extended until the stop is reached. The cooperating camming surfaces prevent the biasing force of the springs from retracting the elongated members when the elongated members are positioned in the downward direction. A cross bar is disposed substantially at the remote ends of the elongated members, and has a water foil surface mounted thereon.
