The SIMSUP5 (S5) is another study in modern displacement hulls for the SUP world. A redistribution of volume and surface area allows this model to be ridden narrower than your normal board with little effect on overall stability. The parallel rail outline makes this one paddle and catch waves like it's a much longer board. Single concave entry and through the middle transitions into a channel bottom to make this model loose and fast with control! Dimensions and volumes can be tailored to suit your individual needs.
