Abstract
Abstract A facility is provided having a body of water and wave generator for producing a continuous wave suitable for surfing. A plurality of generators provides serial waves on opposite sides of a tunnel structure having screen grills for preventing surfers from colliding with the wave generators. Both double bladed and alternatively single bladed wave generators are provided.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
209 words
A surfing apparatus comprising a wave generating means for generating waves suitable for surfing, said wave generating means including a generator unit having blade means mounted thereon, and power means for motivating said generator unit and thereby said blade means, and further including depression means defining an annular depression containing a body of water defining a water level and housing a generally horizontal bottom portion and a pair of side portions, said blade means being within said body of water at least partly below said water level, and guide means for guiding said generating means and said blade means mounted thereon in a generally circular path above said bottom portion and between said side portions of Said depression means so as to product waves which translate to said side portions, said guide means including a generally circular tunnel structure for housing said generator unit defining a top deck portion and open side portions, and rails guiding and supporting said generator unit said depression means also having two side portions for wave attenuation, and wherein said tunnel structure is located on said bottom portion intermediate said side portions whereby waves generated by said generating means travel outward away from said tunnel structure side portions to said depression means side portions.
Claim 2
Dependent Claim
209 words
A surfing apparatus comprising a wave generating means for generating waves suitable for surfing, said wave generating means including a generator unit having blade means mounted thereon, and power means for motivating said generator unit and thereby said blade means, and further including depression means defining an annular depression containing a body of water defining a water level and housing a generally horizontal bottom portion and a pair of side portions, said blade means being within said body of water at least partly below said water level, and guide means for guiding said generating means and said blade means mounted thereon in a generally circular path above said bottom portion and between said side portions of Said depression means so as to product waves which translate to said side portions, said guide means including a generally circular tunnel structure for housing said generator unit defining a top deck portion and open side portions, and rails guiding and supporting said generator unit said depression means also having two side portions for wave attenuation, and wherein said tunnel structure is located on said bottom portion intermediate said side portions whereby waves generated by said generating means travel outward away from said tunnel structure side portions to said depression means side portions.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 further including means for changing the angle of said blades so as to permit changing wave characteristics.
Claim 4
Dependent Claim
28 words
The apparatus of claim 1 wherein said blade means comprises a pair of angled blades oriented so as to generate waves on opposite sides of said tunnel structure.
Claim 5
Dependent Claim
25 words
The apparatus of claim 1 wherein said blade means comprises a single angled blade for generating waves on a single side of said tunnel structure.
Claim 6
Dependent Claim
32 words
The apparatus of claim 1 wherein said generating means comprises a plurality of generator units each mounting a blade unit and power means for motivating each generator unit in said circular path.
