I am curious what is the general opinion about sit-on-top kayaks in this online community.

I know they tend to be more common in warm weather regions. Also, while many sit-on-top kayak models are relatively short and designed primarily for recreational purposes, there are many models out there that are well suited for multi-day touring trips (Wilderness Systems Tarpon 160i, Cobra Expedition, among others).

Personally, I have used sit-on-top kayaks quite extensively for day and multi-day trips. I really like the fact that in the event of a capsize, re-entry is very easy, even in choppy seas. Getting in and out of the boat is also a simple task.

Some possible cons: they tend to be slower than closed cockpit touring kayaks; the bottom hull of the boat is usually flatter and wider than regular kayaks (this adds stability, but reduces the efficiency of the boat while cutting through waves, etc.); the paddler tends to sit higher than in a closed cockpit kayak, losing part of the feel of sitting low in the water.

Anyone with experience using sit-on-top kayaks?

I own both types of boats. Living in Michigan, I bought the SOT first as I was concerned about the rolling aspect of the SINK. I have found that each has its benefits. I am more physically comfortable taking summer day trips in the SOT. For running down flat water rivers and paddling smaller waves on Lake Huron and just plain bobbing around the SOT is the better boat. For skill development and multiday trips on big water, the SINK is preferred by me. The dry storage, additional floatation and longer length make it the preferred kayak for those uses. I bought the SINK specifically for the purpose of touring. The two boats are a Ocean Scupper Classic and a Necky Kyook Plus. So far I have been happy with my choices.

While it is hazardous to gereralize, I think if everthing else is equal, a SOT will be a bit heavier than a SINK and will probably be slightly less stabil. Other than that, the SOT probably won't have all the capabilities of a comparable SINK. If style and performance mean anything to ya, the SINK has to get the nod. If ease of getting in and out is your thing, then the SOT is your deal.

I paddle a RTM Disco (SOT). It's 14' x 26'' and has a sea kayak style hull, as opposed to the usual wider hull designs of most SOT's. Makes it a bit 'tippy', but secondary is great. I can roll it with the thigh straps in place and it's about as fast a poly SOT as I've ever seen. I can keep up with most SINKs unless we're racing, but who races? I paddle in the Carolinas where the water can be close to 90 degrees in the summer, and the air temp is hot too. Can't beat the SOT in these conditions.But I'm working on a real sea kayak (WS tempest or VCP aquanaut) because I live up north on the Delaware river and near the Hudson. These waters are cold most of the year. The Disco is 50lbs and very convenient to haul and paddle. It makes most other poly SOT's feel like barges.
