Abstract: A vessel and seat accessory mounting apparatus includes an inflatable vessel having a flexible vessel floor and a front vessel end and a rear vessel end, a support structure for supporting a person in a seated position, where the support structure includes a top surface, and front and rear wall portions, an elongate member extending from the support structure having a surface substantially parallel to and abutting the vessel floor substantially along the entire length of the elongate member for more widely distributing the weight of the structure and the person over the vessel floor and extending to the front of and to the rear of the support structure, a seat accessory mounting cross-member including a first lateral end and a second lateral end and a mounting port for receiving and passing the elongate member through the mounting cross-member, and an accessory affixed to and extending from the accessory mounting cross-member.

Abstract: A device for shuffling playing cards is described as having a substantially rectangular enclosure with a width that is greater than the length of the playing cards to be shuffled and a height that is less than the width of the playing cards to prevent any of the cards from turning upside down. The length of the enclosure is greater than three times the length of the playing cards to provide room for cutting the cards. Two smaller partitions are placed inside the enclosure at opposite sides to impede the side to side motion of some of the playing cards when the card shuffler is shaken from side to side. The cards whose motion has been impeded settle into various random planar alignments relative to other cards, similar to a "cutting" of the cards. Repeated shaking of the card shuffler intermingles the cards and achieves an effective shuffling action.

Abstract: A seat for use in an inflatable vessel having a vessel floor includes a support structure to place on the vessel floor for supporting a person in a seated position, and a member extending from the support structure for more widely distributing the weight of the structure and the person. The member is preferably an elongate member fitting through openings in the support structure. The support structure is preferably a box including a top surface, and front and rear wall portions joined by side wall portions. Two openings are preferably provided in the front wall portion and two corresponding openings in the rear wall portion and two members for distributing weight are provided and are fitted through the corresponding openings. The members are preferably PVC tubes. The seat preferably includes a back rest portion attached to and protruding generally upward from the support structure.
