K4 Incinerator Rear US SB Windsurfing Fin
The Incinerators! Our new quad fins! Narrower based and a more upright template to give your 4 fin set up more speed and lightning fast direction changes.
There haven’t been any contests this year to prove the worth of these new fins, but Leon took the proto’s to 6th place in the 2019 Aloha Classic with some of the best turns ever seen at the event!
Designed with Adam Lewis who’s been looking to get the best performance from his quads.
Note: You may want to size these a little larger (0.5cm) than your normal preference due to the reduced area and base width.

K4 Scorcher Front US MT SB Windsurfing Fin
Sold as singles for £19.95 each. Please order 2 items for a pair.
The Scorcher fronts. The best choice for your thruster fin board! A wider base for more drive, hold and gouging carves. Like the bigger Scorchers they are thin for maximum top speed and work particularly well for ‘wobble n ride’, onshore, or lighter winds. Available in 9, 10, 11 and 12cm with MT, US and SB (Slotbox/Starbox) heads. These have more drive and grip than the Shark II fronts.

K4 Shark II Slot Box / Star Box PAIR Paddleboard, SUP, Windsurfing Fins
The all new Shark II fronts. Our team riders wanted a fast and grippy fin for both their quads and thrusters. So we set about designing a fin that was sleek and lower tip area using our ‘super stiff’ material. We slimmed it right down to give back some flex and grip, and widened the base to add hold and drive. The result was a fast and precise feeling fin with just the right balance of grip and release. Already taking Alex Mussolini to a podium finish in Tenerife.
Notice that the SB head will now suit both ‘Slot box’ and the new ‘Star box’ which comes with some Starboard and Severne models.
We’ve also added a 1º option to the SB heads. This is for those with straight boxes who wish to add a bit of toe in for a looser feel. Order two SB 1º fins and you will receive a ‘left and right’ pair.
Also available in 8, 9, 10, 11 and 12cm with MT, US, SB (Slotbox/Starbox) and SB 1º.
