If one had to select one of the lesser treasured elements out of the equipment used in windsurfing, it would most likely be a fin. It usually sits under the water mostly and doesn’t get much attention like a sail or a board. But not to forget its importance as it is also doing great and most important tasks for surfers.
As a matter of fact, it is a fin that largely decides how easy and fast you will get surfing and how easy to manoeuvre or controllable or jumping the board would be. Generally, at the time of buying a new board, people get a nice fin along with it. Indeed, it works great for some amount of time. But when the collection of sails gets bigger or if you feel that you need a better performing board, then it is surely worth it to start considering getting a new fin for your board from the windsurf shop.
Types of fins
There are number of shapes and sizes that these fins come in. There are longer, narrower and straighter outlines which are generally dedicated for higher speeds. The ones which are shorter and have a curved end are extremely useful for higher manoeuvrability. This is the basic secret of their construction. Their thickness is the less striking feature. In lighter winds, the fins that are thicker generate more power but they won’t make you go as quick as a thinner fin. Flexibility is yet another important aspect. The fins that are stiffer are constructed for speed, and these are better for manoeuvres and control. In order to achieve the correct amount of flex the individuals needs to be aware of the thickness and materials which is used in the construction of the fin. As a rule, the fins which are stiffer and constructed out of vinyl or polyester resin have more flex as compared to the ones which are constructed out of carbon. As a pro tip, check the flexibility of the fin by bending the tip of the fin while at the windsurf shop.
Considering the construction of fins, you would also notice that their bases has different shapes as well. This is due to the multiple types of fin boxes which are available in windsurfing boards. The fins that are longer need stiffer and deeper seating in the board while the shortest ones generally have to fit in extremely thin tails, therefore, not too much need for space for bigger bases.
