Abstract: A golf putting practice device having a bottom panel, a left side panel, a right side panel, the left and right side panels being connected to the bottom panel, and a notch that exposes a putting surface and that is adapted to receive a golf ball. The left and right side panels are perpendicularly oriented to the bottom panel and spaced apart a distance at least slightly greater than the length of the head of the golf putter. Each of the side panels has a top and a bottom edge, and a plurality of grooves in the top edge. At least one relocatable rod having a length greater than the distance between the left and right side panels is removeably positioned in corresponding grooves in the left and right side panels. The bottom panel is substantially transparent and has a reflective surface in which a golfer can see his or her reflection before, during, and after putting.

Abstract: A motorized pleasure boat having an essentially V-shaped hull. Pairs of strakes are placed on each side of the hull bottom to reduce side slipping and to increase planing efficiency. Stern extensions project rearwardly from the transom to further improve planing efficiency. The stern extensions have inner surfaces which additionally reduce side slipping. The length-to-width ratio of the hull is substantially less than that of traditional hulls.
