Build a Surfboard Episode 1: Shaping

Step 5Plan and Draw the outline

Plan and Draw the outline
Start by drawing the outline or top view of the board on your blank.
Using the wooden stringer as the centerline of the board, Johnny draws horizontal lines at the following places and then measures and draws lines to mark the width there:

Tip
Tail
Midpoint
Point of maximum width - on this board it's 6 inches forward of the midpoint of the board.
1 foot back from the tip
1 foot forward of the tail.

Then he draws smooth curves to connect these points. He's got a quiver of masonite templates from previous boards that help him draw curves he likes. One side of the template is a nose curve, the other side is the tail curve. He flips the template over to draw the four quadrants of the board.

Shaping jargon takes a while to get used to, but it's necessary to understand what makes one surfboard different and better than another. The following phrases will be explained later in the text of this project.
His current shaping philosophy calls for a lot of rocker. He makes "longboards" that are suitable for waves of any shape or size. His boards are faster in turns than they are going straight, which makes them "squirt" and gives them "drive". The rocker prevents them from "pearl diving" or "pearling", so the rider can put their weight very far forward on the board, which also improves "drive".

This board will have "reverse vee" style "concave" in the nose and middle section, a flat spot about the size of two hands right at the tail, and "tucked rails".

For reference, Maui terminology for the different sizes/styles of surfboard are:
Type Size
Performance Board up to 6'8" or 7'2"
Egg 7' to 8'
Mini Tank 8'-9'
Longboard 9' and up
