A swimming aid being configured to increase a user's buoyancy in the water. The swimming aid has a supporting structure with a back float. The supporting structure is designed to secure the swimming aid to a user's upper body. The back float is tiltableseen in useabout a transverse axis connected to the supporting structure. The tilting movement of the back float to the supporting structure enables the user to obtain an inclined, more vertical posture in the water, which will improve the user's ability to keep their head above the surface of the water and also intuitively encourages the user to stretch out their hands to make a supportive movement with the hands in the water. Thus, the swimming aid increases water safety and at the same time promotes swimming skills.

A removable storage device adaptable for use in exercise, fishing, paddling, floating, anchoring and other operations pertaining to, but not limited to, recreational operation of watercraft. This storage device has a population of receptacles or storage areas in which a user may rapidly and securely store a variety of objects such as, for example only, paddles, snorkeling gear, valuable items, waterproof pouches and/or containers, lights, personal flotation devices, dog leashes, fishing poles, anchors, food and/or beverage containers, rope, flares and other desired items. This removable storage device may be constructed to allow secure fastening of the storage device to a wide variety of external surfaces such as, for example only paddle craft, docks, boats and other objects and surfaces desired by the operator. The storage device may be an inflatable device, a solid or semi-solid device, and/or a combination inflatable and solid or semi-solid device.

A vest has a back and a front with a vertical opening, laterally spaced sides with arm holes, a neck hole, a waist hole, an interior surface and an exterior surface. A plurality of front light emitting diodes are on the front of the vest and a plurality of back light emitting diodes are on the back of the vest. A battery and a plurality of solar panels on the vest power the light emitting diodes.
