Abstract: Enhanced surfing by means of waterproof gloves which provide lifting pads spanning the width of the palm from the base of the thumb and terminating near the pinky, or also extending across the upper palm finger pads if desirable, while secured tightly at the wrist. The padding is contoured and rises to prescribed height starting at the base of the wrist, rising to the maximum height near the base of the palm, and then returning to ‘level’ with the hand inside the palm. Similarly, narrower finger pads will follow a similar contour but will have less height than the palm pad. The padding provides a resilient, rebound boost to aid surfers in quickly rising to their feet while simultaneously creating more clearance between a surfer's torso and board to allow for a heightened swing arch to create forward distance for initial foot positioning and added takeoff momentum.

Abstract: A stern drive is for propelling a marine vessel in water. The stern drive has an upper drive unit with a lower mounting surface; a lower gearcase coupled to the lower mounting surface and a trailing end surface that is angled relative to the lower mounting surface; and a propeller shaft extending forwardly from the lower gearcase and being configured to rotate a propeller for pulling the marine vessel in the water. The upper drive unit and the lower gearcase are configured such that when a forward side of the lower gearcase impacts an underwater obstruction, the lower gearcase is caused to pivot relative to the upper drive unit until the trailing end surface impacts the lower mounting surface, which thereby causes the lower gearcase to completely uncouple from the upper drive unit.
