First of all SUP stands for “Stand Up Paddle” and its kind of related to surfing…. um … kind of. Yet there isn’t much of a bond between surfers and sup-ers. We can get to that later. But, why not just kayak? Heres the deal: A sup board glides in the water better than a kayak.
The sup user can change his/her posture at any time, depending on wind, current, or fatigue. They can kneel, sit, lay, or stand. They can also see further because they are standing.
Possibly noting hazards or maybe the best entrance or exit to a particular water way.
