Stand up paddle surfing (SUP),is an emerging global sport with a Hawaiian heritage. To begin with, this started with using a one-bladed paddle, whilst standing on a normal length surfboard. The popularity of the modern sport of SUP has its origination in the Hawaiian Islands. In the early 1960s, the Beach Boys of Waikiki would stand on their long boards, and paddle out with outrigger paddles to take pictures of the tourists learning to surf. This is where the term "Beach Boy Surfing", another name for Stand Up Paddle Surfing, originates.
The sport benefits athletes with a strong 'core' workout. SUP'ing is popular at warm coastal climates and resorts, and is gaining in popularity as celebrities are sampling the sport, and cross-over athletes are training with SUP. SUPs have been spotted around the globe, anywhere where there is easy access to safe waters, as well as in the surfing lineups of the world.
Surfers have converted because of the versatility of the new sport. Stand up paddle boarding offers surfers the ability to catch more waves in a set, as well as offering a better view of incoming sets. (Above text referenced from Wikipedia)
SUP'ing has turned in to a family friendly sport due to its accessibility and ease of learning. It is becoming popular on lakes and rivers throughout the inland states.
