Abstract: A rooftop rack for carrying bicycles, the rack comprising a base which is mounted on the vehicle roof, a pivotable arm connected to the base, the arm being moveable between a first upright storage position and a second outboard position, a first platform for carrying at least one bicycle, a winch mounted on the base, a cable extending from the winch to a distal end of the pivotable arm and to the first platform, the arrangement being such that when the pivotable arm is in the storage position, the platform is retained by the distal end of the pivotable arm while when the pivotable arm is in the second outboard position, the first platform can be released from the pivotable arm. The rack permits loading of the bicycles at ground level from where they can be moved by means of the winch to the stored position on the roof of the vehicle.

Abstract: The bottom surface of the surfboard has a set of transverse ridges which are bowed away from the front of the surfboard, which are symmetrical relative to the longitudinal axis of the board. A channel extends across the edge surface of these ridges and are aligned along the board longitudinal axis. In motion, the moving water not only strikes the rear edge face of the surfboard but also the rear faces of each ridge, thereby increasing its propelling efficiency relative to surfboards devoid of such ridges. A second and a third sets of transverse ridges may be formed in water pockets made on opposite lateral side surfaces of the surfboard. These second and third ridge pockets assist in self-straightening the surfboard should the latter accidentally swerve at least slightly transversely from the general axial direction of displacement.
