People tell me that there's a place in the world for SUPs and that they are great for developing fitness, especially on small days. I thought cycling, running, yoga, skateboarding and weights would be enough to supplement fitness on flat days. People tell me that the SUP design has a lineage going right back to The Duke and the Waikiki beach boys of the 1920s. I see a clever marketing ploy to increase sales revenue for merchandisers. I see bloated boats spoiling the aloha in the line up. I must be a slow learner.
