What Does the Flexure Change?
If you look at your surfboard from the top, you’ll see that its lines have a curve that defines shape – from nose to tail.
You’ll see these curves that make the whole construction not just straight but torque.
First of all, it is a rail line curve and it may differ from board to board in order to change the functions that the surfboard can offer you.
Let’s discuss different types of these surfboard lines and their curves.
The line with a big curve
With such a line, you can implement turns almost without effort because when you ride the surfboard whose rails are round, they go in the water giving you the power to make turns and increase them due to the curve.
At the same time, the easier you turn, the more difficult it is to move with this surfboard directly.
Thus, this shape of the surfboard lines will let you have maneuverability but lead to losing stability.
The line with a small curve
You’ll probably see this line curve on the surfboard constructed for riding big waves including longboards or guns, for example.
In order to increase stability, the area of these surfboards you can stand on is broadened and it lets you cut down the swell you encounter on the water.
At the same time, while riding guns, the line shape allows you to save the speed in huge waves.
However, you might guess that the curve which is not big enough can’t provide you with a good turning ability.
Thus, the turns on such surfboards are uneasy and add to your losing the speed while making them, but a straight ride is just perfect.
A good illustration is the cars. One of them is a sedan, the other is a hatchback. It is quite logical that the first is more difficult in changing the directions but goes pretty well straightforward and the second one is perfect when you need to wind in the alleys.
