Too much overlap you lose this and with sharp turns you get the stalling effect : basically it a twin fin to a degree: On mids and fish not as important, See below first set with lots of overlap board is loose but on back bottom turns it will stall out. Third and fourth picture is same canards but mains are pushed back. Tons more hold but not as loose, need to decrease the canard size to loosen board up. Boards super fun in both set ups but like less overlap for the hold. This is why FCS are great you can adjust fin tabs. Click to expand... Cool. How do you adjust fin tabs on FCS? I appreciate your photos and explanation. To my eye, an arrangement that mimics a split keel would better create the effect you mention: "pressurize the mains"; more than two fins with roughly identical 'swept back' templates. Looks like mains and canards are both totally flat inside surface. |
