Abstract: Pressurized portable solar heated shower having a flexible shower bag with first and second closed chambers on opposite sides of a flexible membrane enclosed within a flexible outer bag. Water is introduced into the first chamber, and a foot operated pump is connected to the second chamber for pressurizing the second chamber with air to expel the water from the first chamber through a flexible hose and shower head. When not in use, the shower bag is emptied, and the entire device can be folded into a relatively small package which is easily carried by campers, backpackers, boaters, and the like.

Abstract: Inflatable kayak having a pneumatically inflatable peripheral tube with elongated side sections which come together fore and aft to form a passenger compartment, a flexible cover encasing the tube and forming a shell against which the tube can be inflated to form a relatively rigid structure. A sheet of tarpaulin material extends across the bottom of the passenger compartment and along the lower and outer sides of the tube, and an inflatable floor cushion rests on the tarpaulin material in the passenger compartment. A seat is provided toward the rear of the passenger compartment, and a splash skirt attached to the cover extends across the passenger compartment between the side sections of the tube in front of the seat.

Abstract: Self-inflating mattress for outdoor and camping use having a body chamber which contains open cell foam for supporting the body and legs of a person resting thereon, and air chambers positioned to the sides of the body chamber for cradling the person and preventing him from rolling off the mattress. The body chamber is reduced in width in the lower back region, and the air chambers extend into that region to provide additional lower back support.

Abstract: Steerable towcraft having a buoyant body upon which a person can ride, a towline attached to body and adapted for connection to the pulling vessel, a fin on the under side of the body for guiding the body through water, and a steering line connected to the towline at a point spaced from the body. By pulling on the steering line, a person riding on the body can change the angle of the fin relative to the towline, and thereby control the direction in which the towcraft is moving. Water is taken in from beneath the body and sprayed in the form of a roostertail into the air behind the craft as it travels through the water. In some embodiments, a whistle or other noisemaker is actuated by the water forming the roostertail.
