The Simster

Planing Hull Tri Fin

The Simster

Simster

The Simster was inspired by Simmons’ attempt to build Bev Morgan a short, tri-finned planing hull nearly sixty years ago. Morgan stubbornly insisted on a single fin and the short tri fin was never built. The Simster has the planing speed of a dual keel Mini-Simmons but with more directional control because of the small trailing fin. It features side fin keels that are designed for drive and long carves. These are placed next to a set of wings designed for maximum planing width.

The Simster is an extremely versatile design and can be ridden shorter than a contemporary thruster. While this is a tri-fin board it has evolved from a fish and Simmons lineage. It has far more planing and paddling speed than a typical shortboard.

Planing Hull

The Mini-Simmons

An excellent starting point for the planing hull experience. It is the widest, flattest, and fastest of all the designs in the line.

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.

Aspect ratio of the planing surface in accordance with concepts explored by Lindsay Lord, Bob Simmons, and Fibonacci.

The Cybersim

The CyberSim is a scaled down version of the original hydrodynamic planing hull designed by Bob Simmons in the 1940s.
