Abstract
Disclosed herein is a method of water board propulsion comprising placing a buoyant board with a flexible water catching pocket having an open proximal end and at least a partially closed distal end affixed to a bottom surface of the water board in a current of water moving at a speed which is faster than the buoyant board; positioning said open proximal end to receive the flowing water; receiving water flow into the open proximal end; and, accelerating the board in the direction the current with greater acceleration than the same board without a water catching flexible pocket.

1-20. (canceled)
A flexible propulsion attachment for a buoyant core water board comprising:
- a substantially flat frame;
- a mounting means on a portion of the frame whereby the frame can be affix to a waterboard;
- at least one pocket having an upper boundary defined by the frame, two flexible pocket sides, a pocket bottom section formed of a flexible material, a distal end that is affixed to the frame and a proximal end that is unattached to the frame, such that opening of the proximal end is larger than the opening of the distal end;
- and,
- at least one opening limiter having a first interface adjacent to the frame and a second opening limiter adjacent to the bottom of the flexible pocket.
The flexible propulsion attachment for a buoyant core water board of claim 1 wherein at least a portion of the pocket bottom is semi-rigid.
The flexible propulsion attachment for a buoyant core water board of claim 1 wherein the pocket bottom is more rigid than the pocket sides.
The flexible propulsion attachment for a buoyant core water board of claim 1 wherein the at least one pocket is affixed to a waterboard post production.
The flexible propulsion attachment for a buoyant core water board of claim 1 wherein the mounting means is an adhesive.
A flexible propulsion attachment for a buoyant core water board comprising:
- a substantially flat frame;
- a series of mounting guides through a portion of the frame whereby the frame can be affix to a waterboard;
- at least one pocket body having an upper boundary defined by the frame, two flexible pocket sides, a pocket bottom section formed of a flexible material, a distal end that is affixed to the frame and a proximal end that is unattached to the frame, such that opening of the proximal end is larger than the opening of the distal end;
- and,
- at least one opening limiter having a first interface adjacent to the frame and a second opening limiter adjacent to the bottom of the flexible pocket.
The flexible propulsion attachment for a buoyant core water board of claim 6 wherein at least a portion of the pocket bottom is semi-rigid.
The flexible propulsion attachment for a buoyant core water board of claim 6 wherein the pocket bottom is more rigid than the pocket sides.
The flexible propulsion attachment for a buoyant core water board of claim 1 wherein the at least one pocket is affixed to a waterboard post production with at least fasteners which extend through the waterboard.
The flexible propulsion attachment for a buoyant core water board of claim 9 further comprising adhesive between the frame and bottom of a waterboard.
