If your board set up is right, it won't only make you go faster, it'll also increase the wind range you can sail it in - both in light air and higher winds.

Following these steps will guarantee maximum enjoyment from your new Roberts Board or kick start your old one!

Fin Size
If there's one question I get asked more than any other, it's what fin I should use? We do have recommended fin sizes for all of our boards, but we only show the average size. There's a little more to it when selecting a fin for optimum performance. For starters, each board should have 2 or 3 fins to work with. This doesn't mean you should go run out and buy 3 fins for every board you own! Most of you have more than one board, so if you make your fin selection carefully, you can spread them through your boards. So take all of your boards into consideration and you'll save a bunch of money. When selecting your fin(s) you should understand your board type and sailing conditions:

Slalom
These boards work best with dedicated downwind slalom shapes. They won't take you upwind like a pointer fin, but they're designed to go off the wind very fast. The length is generally shorter with a longer chord length (width). The chord length helps you keep the board going in a straight line. Other slalom shapes that work well resemble raked back pointers with a wing tip.

Wave and Bump & Jump
Wave fins work best in higher winds for wave and bump and jump boards. They are very swept back with a long chord length. This combines to make the board's curvy rocker go straight - it also forces the board to carve better in and out of the turn, giving maximum control in high winds. I haven't seen too many long wave fins for lighter air, so this is where freeride fins take over. A better choice for lighter winds as their increased length generates more lift - remember, more lift, earlier planing.

The big question is: What Size? Well, that's easy - the right one! Here's how...
Firstly, select a fin which you think will work well in the wind/wave/water conditions you're going to sail in and go out and sail it. Keep in mind to make all the fine adjustments to boom, mast track and sail settings. Start paying attention to what your feet are doing, particularly to the amount of pressure you have on each foot. If the pressure is light on your back foot and you're not able to "push" on the fin, and you end up spinning out, your fin is too small. Consequently, if the pressure on your back foot is high and the board is railing up and getting flighty, your fin is too big. Ideally you want the feeling that your fin doesn't exist except when you need to push on it to go upwind, turn or drive the board harder.
