Fins are way over rated—especially on a Mini Simmons.
My take has always been smaller and lower with fins on the Mini but Tom Wegener has taken the ‘less fin argument’ a few steps forward in his almost fin-less chinned vacuum creation.
Tom Wegener, shaper of the year in Australia, says he got the idea from the rails on a boogie board with “chinned vacuum rails.” He then accentuated the fin set-up with tiny little pegs—forget the keels on this design.
Essentially the idea is that the built-in chinned rail acts as a fin through the length of the board giving some stability through turns and maneuvers.
In fact, this rail replaces the necessity for the traditional keel fin set-up and allows the surfer to pull off radical 360 style maneuvers with ease (see video below).
