Abstract
Abstract A snow surfboard comprising a central body section, a nose section having a gradual nose kick, a tail section having a gradual tail kick which is less than said nose kick, said central body, nose and tail sections being integrally formed, and a pair of turning skegs fixed to the lower surface of said tail section, said turning skegs being laterally spaced from the longitudinal axis of the surfboard and oriented rearwardly at an angle of from 10* to 50* to said longitudinal axis, said turning skegs extending rrom the bottom surface of said tail section a depth such that the bottom edges thereof are tangent to or just above an extension of the horizontal plane of the lower surface of the central body section. The snow surfboard includes a shock absorbing flexible stabilizing skeg running along the longitudinal axis of the surfboard. The snow surfboard is stable and may be controlled by weight shift techniques similar to those used with water surfboards.

Claim 1
Independent Claim
207 words
A snow surfboard comprising a central body section, a nose section having a gradual nose kick, a tail section having a gradual tail kick which is less than said nose kick, said central body, nose, and tail sections being integrally formed, and a pair of turning skegs fixed to the lower surface of said tail section, said turning skegs being symmetrically laterally spaced on opposite sides of the longitudinal axis of the surfboard and oriented to diverge rearwardly at an angle of from 10* to 50* to said longitudinal axis, said turning skegs extending from the bottom surface of said tail section a depth such that the bottom edges thereof are tangent to or just above an extension of the horizontal plane of the lower surface of the central body section, a shock absorbing flexible stabilizing skeg running along the longitudinal axis of the surfboard from approximately the point at which the central body section merges with the nose section to a point at which the central body section merges with the tail section, said stabilizing skeg blending smoothly into the lower planing surface of the board at the juncture of the nose section and central body section so as to facilitate the smooth flow of snow.
Claim 2
Dependent Claim
207 words
A snow surfboard comprising a central body section, a nose section having a gradual nose kick, a tail section having a gradual tail kick which is less than said nose kick, said central body, nose, and tail sections being integrally formed, and a pair of turning skegs fixed to the lower surface of said tail section, said turning skegs being symmetrically laterally spaced on opposite sides of the longitudinal axis of the surfboard and oriented to diverge rearwardly at an angle of from 10* to 50* to said longitudinal axis, said turning skegs extending from the bottom surface of said tail section a depth such that the bottom edges thereof are tangent to or just above an extension of the horizontal plane of the lower surface of the central body section, a shock absorbing flexible stabilizing skeg running along the longitudinal axis of the surfboard from approximately the point at which the central body section merges with the nose section to a point at which the central body section merges with the tail section, said stabilizing skeg blending smoothly into the lower planing surface of the board at the juncture of the nose section and central body section so as to facilitate the smooth flow of snow.
Claim 3
Dependent Claim
53 words
A snow surfboard as claimed in claim 1 wherein said stabilizing skeg comprises a flexible metal strip spaced in its intermediate regions from the bottom surface of said board, and wherein pillars of a resilient material are included between the bottom surface of said board and said stabilizing skeg in its intermediate section.
Claim 4
Dependent Claim
29 words
A snow surfboard as claimed in claim 2 wherein said turning skegs are oriented at an angle of from 30* to 35* from the longitudinal axis of said board.
Claim 5
Dependent Claim
20 words
A snow surfboard as claimed in claim 3 wherein the depth of said turning skegs increases from front to rear.
