The Plantain has 50/50 rails in the front of the board for finding the perfect slot when nose riding.  And with it’s soft concave, the Plantain nose rides very well.  It has down turned rails at the tail and some seriously deep tunnels next to the fin.  Hard corners on (true) square tails are a little bit too stiff feeling for some surfers.  The ever so slightly rounded corners on the square tail of the Plantain give it the positive feel coming out of a turn that a true square tail gives.   But they are just soft enough for great flow; connecting front to backside turns.  And the Plantain hasbetter drive out of the turn than the softer feel of squash tails and pintails.
