Why Two Fins Are Better Than One
The advantages of two fins on the surfboard instead of one are obvious.
Two flippers help to achieve the speed you’d never experienced and the ability to implement tricks and sharp turns during riding.
In comparison with three fins, this variant with two lets the surfboard move smoother, not so tight, and with greater control.
The designs that are usually combined with two fins are the shortboard and the fish.
Mark Richards who has been the world champion four times believes that the two fins have influenced his style of riding and catching the waves and helped him to win.
His answer to the question about why he has been fond of the twin-fin surfboards consists of the facts about his favorite surfboard configurations: the back end is wide enough to add to flotation and, moreover, the surfboard responses come in a wink which influences the whole process of going into the waves.
The location of the two fins on the surfboard may vary.
One of the most widespread methods to fix the flippers is to put them nearby rails and close to the end of the surfboard so that the two fins could work in a classical way.
There are a lot of options for how the flippers may be placed: either being fixed by the stringer or positioned to a vertical location.
Each way has its own unique features.
The two fins that are included in a twin-fin setup may be different in height and width. When it comes to the fish board, you’ll probably see two fins of a large size.
The back end of the surfboard will be formed in the shape of the swallow or some other shape because the round variants are multiple.
Advantages
One of the most apparent pros is the maneuverability the surfer can achieve with twin-fin surfboards. He can literally switch the way he rides.
In the process of a turn, two fins act in a different way: one of them will stand at the point of turn and the other will go as if shaping the semi-circle.
The effect of this is clear – the surfboard will take the place you have aimed it to take.
One more mentioned pro of the two fins is the speed. As there is no fin causing drag, the surfboard moves fast and even faster than you desire.
Disadvantages
On the other hand, high responsiveness means that the two fins will not provide the surfer with control in severe conditions.
As a result of turning, the surfboard might sneak out from the position you’d like it to take.
The difficulties may also appear with waves-barrels when, inside of them, the surfboard will behave unexpectedly and the slippery effect may occur.
Suitable Conditions
Waves with the height from 1 to 6 feet (1.83 meters) are the best to ride with the two flipper setup for beginning surfers while the experienced ones will enjoy riding it when the waves are 2-4 (1.22 meters) feet high.
To Sum Up
The surfboard with this fin setup is universal and suitable for versatile conditions.
That’s why it is a common choice of surfers with different levels.
