Like many paddlers, I used to consider Sit On Tops (SOT) as a lesser kayak, one for beginners and novices and this is true, to a point.
The explosion of SUP is a fine example that simplicity is what many people are after when it comes to getting out and enjoying the waterways. SOT Kayaks have elements of simplicity and accessibility allowing people with limited experience to safely explore rivers, lakes, canals, and coastal waters without the ubiquitous "what if I get stuck in it upside down." It was for this reason that the early 2000s saw huge sales of these craft, in fact, aged 15 working at my local canoe shop I sold hundreds of these to families looking to have something they could take away on their summer camping trip.
