Adding a single channel

In this tutorial we cover the basics of adding a single channel to the bottom contours of a design. This channel runs from center of the surfboard to the edge of the tail and is approximately 3" off the stringer on both sides. 

"Channels are a design tool to cut paths for water and air to pass quickly, with forced direction, though the bottom curves of a surfboard. Similar to concaves, of course, but more dramatic and usually more focused." - ...Lost Surfboards
