Sit-on-tops have similar hull shapes to their traditional counterparts, but instead of sitting inside the kayak, you sit in a molded-in depression on top.

Some are fiberglass, but most are made from tough, inexpensive, roto-molded plastic.

Sit-on-tops share many benefits with traditional sit-insides, but often are easier to use and less expensive.

There are sit-on-tops for fishing, surfing, touring, scuba diving and more. Some of these are considered specialty boats, but most sit-on-tops are built for multi-purposes and with recreational or beginning paddlers in mind.

Sit-on-tops have a few advantages over sit-insides, one of which is comfort.

Paddlers with large body types, long legs, or limited flexibility feel less confined paddling a sit-on-top.

One of the biggest benefits, though, is the self-rescue.

Because sit-on-tops have an open deck rather than an enclosed one, there is no risk of being trapped in the boat if it tips over-no need to practice rolls or wet exits.

That really appeals to new paddlers, and people who don't plan to take their kayaks out on expeditions.
