Course Outline

You also should consider the board’s rails and depth when selecting a paddleboard.


The shape and volume of the rails affects the board’s stability.

  • Stand-up paddleboards with rounder rails usually are less stable, and those with square rails are more stable. Rounder rails also increase the board’s speed.
  • Rails with more volume make the paddleboard more stable.


A paddleboard’s depth tells how far the fin goes into the water. Depth affects both the board’s stability and its maneuverability in surf. Fins with greater depth give you more control but also have more drag.
