Maybe some shots of the tail concaves?\n\n\n\n\n\n\n\nSomething important to keep in mind with bonzer (or honestly any board for that matter) fin placement... it's not a standard rule/metric across all boards of the same design. Tail width, amount of rocker, amount of V, and style of riding you want to evoke all reallllllllly really matter.\n\n\n\n\n\n\n\nMany times, those \"vets\" on Sways will tell you it's black and white.. but from a scientific perspective it's not. Like adding/moving/removing a dorsal wing to an airplane.\n\n\n\n\n\n\n\n\"call me crazy\" but recently I've been doing 0 degrees of toe on my bonzers, and only 18 degrees of cant. more drive, and for east coast hollow waves that you'd want to ride a bonzer in, isn't that all you really care about? I'm not selling bonzers to Alex Knost to do vertical turns on in perfect Mexican pointbreaks, I'm selling to weekend warriors on the east coast..\n\n\n\n\n\n\n\n\ntry to post a picture with it under your shadow-boxes so that we can see how far off the rails your channels start/end.\n\n\n\n\nClick to expand...\n\n\n\n\nThe Proof is in trying things outside of the box. You're definitely right: more vertical fins have more drive as do no toe in. However conventional shape flat foiled inside fins derive their drive from tracking.\n\n\n\n\n\n\n\nIn the 80's I did a LOT of experimentation while producing a lot of sailboards.  This extensive R&D consciousness spilled over to the surfboards we were building.  We had our own in house fin production, and this was a fin foil I  built for surfboards, also with NO TOE IN.  This foil does not track with parallel to the stringer placement (aka no toe in).\n\n\n\n\n\n\n\nDefinition.
