This Design works Especially Well in Larger Down the Line Waves; when you need to Stay High on the Wall and Retain Good Speed, as it Provides Great Hold and Flow, Excellent for Tube Riding.

The Narrow Plan Shape, with the Base Moved to the Tip of the Fin, Provides More Drive as the Area is Deeper into the Water, where it Gives More Efficient Thrust.
The Narrow Plan Shape also Allows the Board to Go from Rail to Rail, making it Easy to Turn.

This Design has been Tested over Many Years by my Test Pilot Alastair McDiarmid in a Very Wide Range of Wave Sizes and Conditions, in Australia, Hawaii, Indo and the South Pacific Islands.

All Australian made laid up fibreglass fins
