Prone foiling

Patents from this period record attempts to put hydrofoil assemblies beneath surfboards and related craft. They are evidence of documented designs, not proof that one person created modern foil surfing. Many of these systems were difficult to start, heavy to control or dependent on towing.

A new generation of wider, more efficient wings produced useful lift at slower speeds. That changed the question from whether a foil could ride a wave to whether a rider could catch the wave without a tow. Builders and riders tested many combinations of mast length, wing area and board volume.

Prone riders need enough board to paddle and catch a wave, but less board once the foil is flying. Compact shapes reduced swing weight and made turning easier. The take-off became a precise sequence: paddle, catch, hold the board down as it accelerates, then let the foil rise gradually.

Prone foiling now has its own boards, wing ranges and approach to wave selection. It can use small, unbroken swell that a conventional surfboard would pass over. That access also brings responsibility: the mast and wings are rigid equipment, so space, control and careful launch choices matter.
