In the lulls or for relaxed cruising, this fin offers superb low drag due to the use of Tribal Windsurfing Optimised Profile. You won’t notice the fin. It will disappear from your concern. If you don’t need all the power it can handle, go smaller in size for bonus drag reduction. We recommend using 2cm smaller than normal to get the best match. But if you want extra power in a given size, then these fins deliver in spades, with zero compromise on top speed and efficiency!
