For small and medium waves with insufficient energy, surfboards with double identical fins will be an excellent solution for perfect work.
This principle of work was invented in the 60s in California. In the late 70s, Mark Richards revealed the abilities of a surfboard with two fins when he won four world championships one after another.
With this, he made a sensational discovery in the world of surfing.
In the late 70s in Hawaii, MR worked for about 30 days on the shaping technique with the famous Dick Brewer. With particular zeal and resourcefulness, MR began the process of creating a board with two fins.
The result of his work was called Free Ride Twinfin. The advantages of such a surfboard with a double fin are an increase in its speed and maneuverability as well as greater stability at fin work.
This kind of board can become, in some way, your work engine. The double fin can be installed both in traditional and in more modernized forms.
According to MR, he was able to win so many victories only thanks to the power of the surfboard with two fins.
One of the latest inventions is the installation of an additional fin to achieve greater stability at work. MP calls such a surfboard The Super Twin.
We had to turn to the developer himself to understand how this equipment works and what additional fin gives it. MR himself is still developing surfboard forms for his own brand.
He is engaged in the production of not only classic surfboards but also those with large volumes and work productivity. His new board is a modification of the classic form.
And so we met with Richards in Australia.
SurfScience: You achieved many victories in the 70s when you rode a surfboard with two fins. How is such a board different from the one you had used before?
Mark Richards: I switched to a new type of board with two fins because I did not have enough performance in the old one.
One fin was suitable only for riding in Hawaii because the competition took place at short distances and did not require high power.
On a surfboard with a double fin, you can engage in the battle with the waves. The wider tail of such a surfboard gives it buoyancy and the doubling of the fin makes it easier and freer to drive along the way.
Thus, this surfboard helps to rise as high as possible from the bottom and works well from the surface of the water.
With this board with a double fin, I drive most efficiently since it allows me to improve my position on the top of the wave.
SS: We know that, initially, this kind of surfboard with two fins is a priority in unprofessional surfing. So, the double fin works perfectly and is well-suited for those who are just starting their way and are afraid to take risks.
But you have proved that this board also works conveniently in extremely high and strong waves. What should the manufacturer pay attention to in order for the surfboard to work with the best efficiency?
MR: A double-fin surfboard will work perfectly even in the worst of situations. The main thing is that it should be made efficiently and wisely to work smoothly.
The item works well thanks to a set of parts in its design: the position of the fins and their shape, the contour of the tail and the combination of rockers that work together.
In my surfboards, I pay special attention to the edges of resin throughout the lateral space and also, I make a concave wing with a corrugated surface at the bottom for better work.
Thanks to this, my surfboards are more stable, do not glide too much on the water, and lend themselves well to control.
SS: What position should the base and fins be in relation to each other?
MR: Two fins should be tilted inward and enough to stick out from the outside to work well.
If they are installed parallel to each other and, at the same time, they do not stick out from the outside, they will not work smoothly to bring the expected result.
SS: Who should use such a surfboard? What result can a surfer expect?
MR: A surfboard with a double fin may appeal to those who want to quickly change speed and get the maximum power in non-professional sports.
It should be remembered that, at first look, this surfboard may seem sliding and unstable but you will get used to its work. To cope with such equipment requires practice.
SS: People respond positively to this surfboard. Does The Super Twin win if you put it next to the thruster?
MR: I adore this surfboard so much that I would never trade it for any other. Even if I had to choose from all the possible boards in the world, I would choose this one.
The double fin is the best combination of increased maneuverability and engine power that really works.
Unlike the thruster, this surfboard is more mobile, it is easy to control and do unexpected maneuvers. She is definitely the best for me.
