A surfer aims to find the pocket of the wave.
Through trim angle and carving the face speed can be harmonized with pitch.
To trim- wide turn- across the mountain (wave) face is to pitch in perfect accordance to the speed necessary to stay in the pocket.
The pocket being the ideal positioning on the wave where the pitch is just enough to propel momentum without outrunning the curl unnecessarily. To carve- tight turn- is to harness speed through edge control.
Depending on the angle of the slope defines the degree in which the rider must point down the fall-line to generate speed. ie on flat green circle runs one may direct down the fall line to perpetuate speed, whereas on steep black diamonds one may direct across to control speed.
This may seem a foreign concept or misinterpreted as traversing for the common mentality of top to bottom as direct as possible snow sliding. Traditional twin tip boards are designed to check speed through a swinging of the rear foot in a slashy wash maneuver redirecting the board back and forth to break across the center of the sidecut between the feet. While this is effective for survival while plummeting down a mountain face, it is also wasting a lot of energy and fairly abrasive to the slope.
To refine one's ride efficiency it is essential for the utilization of the terrain itself to generate and reduce speed, and for the rider to read the slope accordingly and maneuver appropriately to remain in the pocket. In this fashion there is ultimate perpetuation of energy without waste and the lines left behind artistically trace the contours of the terrain.
According to the shape of the board, subtle weight distribution had radical effects in direction.
