Abstract
A water ski having an elongated body member having a fore-zone, a mid-zone, an aft-zone and a longitudinally extending X-axis. A major longitudinally extending groove is formed in the bottom surface of the water ski and it extends substantially the length of the mid-zone and the aft-zone. A plurality of longitudinally spaced left side minor grooves and right side minor grooves extend outwardly from the boundary edges of the major groove toward the respective left and right side edges of the water ski. Water traveling along the length of the major groove will also travel laterally outwardly through the respective left side and right side minor groove to give improved performance to the water ski.
Claims17
A water ski comprising:
- an elongated body member having a top surface, a bottom surface, a front tip end, a rear tail end, a left side edge, a right side edge, a longitudinally extending X-axis, a length L1, a width W1 at its widest point and a thickness T1;
- at least one major longitudinally extending groove formed in said bottom surface and said major groove extends a length L2 and L2 is less than L1;
- said at least one major groove having a left boundary edge and a right boundary edge;
- at least one left side minor groove in said bottom surface of said elongated body member extending laterally from said left boundary edge of said major groove toward said left side edge of said elongated body member;
- at least one right side minor groove in said bottom surface of said elongated body member extending laterally from said right boundary edge of said major groove toward said right side edge of said elongated body member;
- and
- each of said right side minor grooves and said left side minor grooves have a longitudinally extending K-axis and said K-axes are oriented at an acute angle A with respect to said X-axis of said elongated body member.
A water ski comprising:
- an elongated body member having a top surface, a bottom surface, a front tip end, a rear tail end, a left side edge, a right side edge, a longitudinally extending X-axis, a length L1, a width W1 at its widest point and a thickness T1;
- at least one major longitudinally extending groove formed in said bottom surface and said major groove extends a length L2 and L2 is less than L1;
- said at least one major groove having a left boundary edge on said bottom surface and a right boundary edge on said bottom surface, and an upwardly extending upper surface extending between said left boundary edge and said right boundary edge;
- at least one left side minor groove having a front end and a rear end formed in said bottom surface of said elongated body member;
- said at least one left side minor groove extending laterally from said left boundary edge of said major groove toward said left side edge of said elongated body member;
- said front end of said at least one left side minor groove intercepts said upper surface of said major groove at a location above said left boundary edge of said major groove so that a portion of water flowing along said major groove is directed laterally outwardly along said at least one left side minor groove;
- and
- at least one right side minor groove having a front end and a rear end formed in said bottom surface of said elongated body member;
- said at least one right side minor groove extending laterally from said right boundary edge of said major groove toward said right side edge of said elongated body member;
- said front end of said at least one right side minor groove intercepts said upper surface of said major groove at a location above said right boundary edge of said major groove so that a portion of water flowing along said major groove is directed laterally outwardly along said at least one right side minor groove.
