Hydrodynamica Test Pilot Series

The Hydrodynamica Test Pilot Series

Simmons Inspired Design

The Hydrodynamica Test Pilot Series is a collection of surfboards inspired by the work of Bob Simmons in the late 1940’s and early 1950’s. They are contemporary interpretations of the Simmons planing hull that have evolved through the Hydrodynamica film project.

Riding a planing hull and discovering its place in surfing’s past and its relevance in the present is a rewarding experience for surfers of all ability levels.

The boards shown here are the result of collaborations between Simmons historian John Elwell, Hydrodynamica project director Richard Kenvin, keel fin craftsman Larry Gephart and shapers Hank Warner, Larry Mabile, and Carl Ekstrom.

The Mini-Simmons

Planing Hull Dual Keel

The Mini-Simmons

The Mini-Simmons has brought Simmons to life for an entire generation of surfers more than five decades after his death.

The Simster

Planing Hull Tri Fin

The Simster

The Simster was inspired by Simmons’ attempt to build Bev Morgan a short, tri-finned planing hull nearly sixty years ago.

The Fourke

Planing Hull Quad

The Fourke

The Fourke features a quad keel set up with single foil Gephart front keels backed with basey double foil trailing fins.

The Ekstrom

Planing Hull Asymmetric

The Ekstrom

Carl Ekstrom innovated the asymmetric surfboard in the mid Sixties. Asymmetry helps loosen the heel side rail of a planing.
