A kickboard having a rigid base of generally thin, rectangular, shape. At least one shallow cutout or depression is formed in the top surface of the base, the depression extending rearwardly from near the front edge of the base and being at least wide enough and long enough to receive a swimmer's arm when the swimmer grips the front edge of the base with his hand. A layer of cushioning material can be provided in the depression to cushion the arm of the swimmer while gripping the board by the front edge. The front edge of the board is rounded and at least partly cushioned as well. A groove is provided in the bottom surface of the base positioned to receive the finger-tips of the swimmer while gripping the front edge. A second groove can be provided in the top surface of the base, just behind the finger-tip groove, for receiving a portion of the palm of the swimmer's hand while gripping the front edge.

A kickboard as claimed in claim 1 having third shallow depression formed in the top surface of the bas the third depression extending rearwardly from at least near the front edge of the base to at least near to the back edge of the base; the third depression being at least wide enough to receive, and to help retain, the arm of a swimmer between the sides of the depression on the base when the swimmer grips the center of the front edge of the base with his hand, the third depression located between the first and second depressions.3. A kickboard as claimed in claim 1 including a finger-tip receiving groove in the bottom surface of the base just behind the front edge of the base and a rear-palm receiving groove in the top surface of the base parallel to the finger-tip groove and located just behind it, the grooves in front of and transverse to the depressions.4. A kickboard as claimed in claim 2 including a finger-tip receiving groove in the bottom surface of the base just behind the front edge of the base and a rear-palm receiving groove in the top surface of the base parallel to the finger-tip groove and located just behind it, the grooves in front of and transverse to the depressions.5. A kickboard as claimed in claim 1 including a cushioning layer in the depressions.6. A kickboard as claimed in claim 2 including a cushioning layer in the depressions.7. A kickboard as claimed in claim 3 wherein the front edge is rounded; a cushioning layer in the depressions, the layer extending forwardly over the rear-palm receiving groove and over at least a portion of the rounded front edge of the base.8. A kickboard as claimed in claim 4 wherein the front edge is rounded; a cushioning layer in the depressions, the layers extending forwardly over the rear-palm receiving groove and over at least a portion of the rounded front edge of the base.9. A kickboard as claimed in claim 5 wherein the front edge of the base, at least in front of the depressions is rounded; the front of the cushioning layer wrapped about at leas the top part of the front edge of the base to form a rounded cushion front edge on the kickboard.10. A kickboard as claimed in claim 6 wherein the front edge of the base, at least in front of the depressions is rounded; the front of the cushioning layer wrapped about at leas the top part of the front edge of the base to form a rounded cushion front edge on the kickboard.11. A kickboard as claimed in claim 9 including a rear-palm receiving groove in the top surface between the depressions and the front edge, the groove covered by the cushioning layer, the groove positioned to receive the rear palm of a swimmer is he grips the rounded edge of the base with his fingers.12. A kickboard as claimed in claim 10 including a rear-palm receiving groove in the top surface between the depressions and the front edge, the groove covered by the cushioning layer, the groove positioned to receive the rear palms of a swimmer as he grips the rounded edge of the base with his fingers.13. A kickboard as claimed in claim 1 wherein the first and second spaced-apart depressions are joined by a transverse depression in the top surface of the base at the front of the base, the transverse depression extending across the width of the base.14. A kickboard as claimed in claim 1 wherein the front portion of the base in front of the depressions is thinner than the remainder of the base and has its top surface merging with the bottom surface of the depressions; and a cushioning layer covering the bottoms of the depressions and at least the top sur ace of the front portion.15. A kickboard as claimed in claim 14 including a rear palm receiving groove in the top surface of the front portion of the base located just behind the front edge, the groove extending substantially across the width of the base, the cushioning layer covering the rear-palm receiving groove.16. A kickboard having: a rigid, buoyant, base; the base longer than it is wider and being less than twenty-six inches in length; the base having side edges, a front edge and a back edge joining generally parallel top and bottom surfaces which surfaces define the planar shape of the board; and two cushioning layers on the top surface of the base extending generally rearwardly from at least near the front edge of the base to adjacent the back edge of the base over a major portion of the length o the base; one cushioning layer adjacent each side edge of the base, the cushioning layers sized in length and width, and positioned, to fully cushion the arms of the swimmer when he grasps the front edge of the base with his hands.17. A kickboard as claimed in claim 16 including a third cushioning layer on the top surface of the base, centrally located on the base between the first two layers and as long as the first two layers, the third layer wide enough to support a swimmer's arm when he grasps the front edge of the base.
