HULL CONTOURS

HULL CONTOURS:Utilized at Proctor

CONCAVES

-Allows air to accumulate beneath the board.
-Gives water a straighter route along the bottom of the board while maintaining the outside rail line as a source of turning and holding power.
-Concaves are usually used in combination with extra rocker for increased turning ease.

SINGLE-TO-DOUBLE CONCAVES

-Very fast through turns; operating off each individual concave in the water during a turn.
- Most widely used high performance bottom design.

FLAT BOTTOM-TO-DOUBLE CONCAVES

-Predictable in all conditions.
- Also quick with good carry through flat sections on a wave.

VEE/CONCAVE COMBINATION

-Concave vee under the front foot, turning to double concaves which carry through a deeper single concave in the fin area.
-Vee concave under front foot is a rail-to-rail pivotal transition point, while the concaves through the tail give the board acceleration.
-Excellent for drivey rail-to-rail surfing.

DOUBLE CONCAVE-TO-DROP ROCKER

-Shallow double concaves under the front foot which drop into a deeper single concave through the fin area.
- Water is able to take a very direct path through the tail providing a board which has the sensation of squirting through turns.

FLAT BOTTOM

Guns: Used in combination with panel vee or concave vee. Powerful waves generate incredible board speed. A flat bottom contributes a predictable, controllable feel to the board . Vee out the tail transitions turning from one rail to the other.

Fish: Also commonly used for small wave boards. Flat bottom to concave vee has excellent trimming speed, is very predictable and carries well over flat spots on waves lacking power.

REVERSE VEE

Available for guns, semi-guns, and hollow wave shortboards. A very custom order basis, this bottom propells the board with amazing speed when turns are executed fully on rail. The natural home for the reverse vee is in large, well shaped power pits for this is where their best qualities are brought to full light.
