We have another pre order period for the pretwisted SR fins again. Available with Minituttle base or Slotbox, with 4.3° angle for boards with paralel finboxes, 3.5° angle for boards with 0.8 to 1° angle (fx Duotone) or 2.5° angle for boards with 1.8° angle in the boxes (fx Simmer). With the greatly reduced drag, improved drive and more natural and tighter turning, you can choose bigger side fins and a (much) smaller centre fin, which gives much more control and maneuvrability with still at least equal up wind ability. We keep getting amazing feedback from customers how much these improved their board. Read more on the how and why behind these fins here: https://witchcraft.nu/boards/trifin/
As there are many variations with the different fin systems, angles and fin sizes, it is impossible to keep a large stock of them all so it is adviced to pre-order these fins. You can order by email to info@witchcraft.nu. Deadline 1st of August 2025. For pricing look here: https://witchcraft.nu/accesoires/fins/ We advice the Witchcraft centre fins for the trailing fin(s) to have all fins working optimally together with the same profile and twist properties. Check the Witchcraft board ranges for choosing the optimal sizes for your board. K4 fins has a toe-in calculator tool on their website to check the angle of your board if not paralel.
