Water devices and methods for making and using such devices are described. The devices contain a main part for buoying a user's body and a part for supporting the body. The supporting part is releasably connected to the main part by a mechanism which is easily adjusted when not in use but remains fixed when in use. The device also can contain a handle for the user. These devices can be used in all areas of the water, including swimming, exercise, instructional, recreational, and the like.

I claim: 1. A flotation apparatus configured for supporting a user in a body of water, comprising: an elongate buoyancy body comprising two elongate tubular portions joined at a common apex and having free distal ends, the tubular portions extending at an angle and being movable with respect to each other, a longitudinally extending slit formed in each of the tubular portions, each slit extending from an outer surface to an inner surface of the respective tubular portion; and a support structure releasably connected to the elongate buoyancy body, the support structure having side portions and front and rear edges, the side portions of the support structure extending through the slits of the tubular portions to be connected to the tubular portions without the use of a sleeve, the rear edge of the support structure being adjacent the free distal ends of the tubular portions, the front edge of the support structure being substantially aft of the apex so that the front edge is closer to the distal end of the tubular structure than to the apex, wherein an opening is defined by the elongate tubular portions and the front edge of the support structure. 2. The flotation apparatus of claim 1, wherein the apex comprises a cut at which the two elongate tubular portions are bonded together. 3. The flotation apparatus of claim 1, wherein the elongate tubular portions comprise foamed plastic. 4. The flotation apparatus of claim 1, further comprising a handle proximate the forward end of the apparatus. 5. The flotation apparatus of claim 1, wherein the slits are formed in the inner sides of the elongate tubular portions. 6. The flotation apparatus of claim 1, wherein the slits are formed in the upper sides of the elongate tubular portions. 7. The flotation apparatus of claim 1, wherein the slits are formed in the outer sides of the elongate tubular portions. 8. The flotation apparatus of claim 1, wherein the support structure is at least partially wrapped around the tubular portions. 9. The flotation apparatus of claim 1, wherein the support structure is not wrapped around the tubular portions. 10. The flotation apparatus of claim 1, wherein the side portions of the support structure comprise friction means for a releasable connection within the slits of the tubular portions. 11. The flotation apparatus of claim 1, wherein the forward end of the apex has a substantially pointed shape. 12. The flotation apparatus of claim 1, wherein the forward end of the apex does not have a substantially pointed shape. 13. The flotation apparatus of claim 1, further comprising extending means to adjust the length of the tubular portions. 14. The flotation apparatus of claim 13, wherein the extending means comprise coupling members for a frictional attachment with the corresponding tubular portions. 15. The flotation apparatus of claim 13, wherein the extending means comprise foamed plastic. 16. The flotation apparatus of claim 1, wherein the tubular portions have substantially circular cross section. 17. The flotation apparatus of claim 1, wherein the tubular portions have substantially elliptical cross section. 18. The flotation apparatus of claim 1, wherein the tubular portions have polygonal cross section.
