HOW IT WORKS...
Bullet Fin riders report increased speed and drive from their boards and reaching
planing speed more quickly.
What's going on? ....
The Bullet Fin's patent pending bulbous design is based on 50 years of experimental
Naval Architecture and applied hydrodynamic research on the bulbous bow hull design.
The bulbous bow is now the standard hull design for many types of ships.
The Science...
Just as with the bow of a ship, the traditional surfboard fin creates a wave as it
displaces the water in its path. The resulting turbulence places drag on the surfboard.
The bulb of the Bullet Fin greatly reduces this drag by creating a new (primary) fin
wave in front of the original (secondary) wave. This new bulb wave is designed to be
nearly 180 degrees out of phase with the original fin wave to subtract its turbulence
thus reducing fin drag.
The result is a fin that gets more efficient as you approach the surfboard's optimal
hull planing speed. |
