SLALOM FINS – 2014 BUYER’S GUIDE

David Gollick of windsurfingfins.co.uk gives an overview of the types of Freeride fins and constructions available on the market.

SLALOM FINS ARE PERHAPS THE MOST TECHNICAL-TO-SAIL FOILS. WITH MANY VARIANTS OF BOTH SPEED AND CONTROL TO PICK FROM. MADE FROM EITHER G10, BUT MAINLY CARBON, SLALOM FINS CAN COVER A MASSIVE BOARD AND SAIL RANGE.

USER
Dedicated racing fins vary enormously, dependent on the brand and the level of the rider they’re targeting. They also demand a little more technique and are much less user friendly than the Freeride Fin. The user can range from the local guy who may not race competitively and just reaches up and down, right up to the downwind course specialist on the PWA tour.

DESIGN
There are variations to the outline of a Slalom fin. Traditionally they’ve taken an elliptical shape, which is time-tested. Over time there’s been a move towards a more high-aspect shape, which tapers off to a more pointed tip. Different outlines breed different characteristics.

Outline: For example a wide blade with a wide tip has a larger surface area that will make the board plane earlier with good upwind ability. By contrast, more slender, high-aspect shapes of the same size (depth) have less area and will plane slightly slower and be less effective upwind – yet have a speed advantage on a reach.

Foil: Some fins have wide shapes with a thin foil thickness which give both good upwind ability and good off wind speed. Others are just off wind specialists that may suffer slightly upwind.

Heads: The majority of Slalom Fins use a Tuttle fitting with Deep Tuttle being used in sizes from around 46cm and above.

CONSTRUCTION
The Trend appears to be leaning toward Carbon rather than G10. Carbon gives the best combination of strength and lightness. Moulds are used to create the shape of the foil. These are generally made from Aluminium, but some can be Carbon made themselves. The process is more labour intensive than that of a machined G10 fin. Each layer of fibreglass and Carbon sheet is meticulously laid into the mould together with epoxy resin and rolled under pressure. This is repeated until the mould is full.

Flex: The next dilemma is the stiffness. With many Brands having a choice of 3-5 stiffness variations, it can be confusing to the un-initiated. As a rule a softer fin is less powerful but more controllable. Heavier riders tend to favour stiffer fins. Most brands will actually give you their recommendations when ordering as there is an optimum stiffness per sized Fin. G10 is still the mostly used material for all Fins. It will outlast the Carbon fin if it in most cases. The issue with G10 is the physical weight. When using a Slalom fin beyond 46cm G10 becomes rather heavy. Add a Deep Tuttle head and it starts to weigh over 1 kilo. The same sized Carbon fin will weigh in at around 650g. Fins up to 44-46cm work fine in G10 but beyond this Carbon gives a better bend curve and lightness.

CONCLUSION
So, in short there are a lot of choices to be considered, with most purchasers it is generally down to price as this tends to shape the product we end up with. If you are in the market for a new fin then consider the information and think of all the parameters that you are looking for – or just call me and I will do it for you! www.windsurfingfins.co.uk
