Last year my wife and I rented a couple of SOT kayaks and used them to paddle around our local lake. We enjoyed it so much we have decided to purchase our own this year.
We are looking at some entry level kayaks to use at the lakes and rivers here in Illinois. 
I am also an avid fisherman and I would like to get a fishing kayak but I don't know if there is a difference, performance wise, between a fishing kayak and a touring/recreational kayak. I don't want to struggle to keep up with my wife if we decide to kayak for 4 to 5 hours on a river or lake.
Would I be able to use a fishing kayak like a regular touring/recreation kayak?

Thanks

There are a few differences between the SOT kayaks and a touring kayak that you'll want to consider. 

**Length** 

SOT kayaks tend to be shorter and wider than touring boats. This can make SOT's a little more stable but a longer boat will track better (go straight). The more rough the water you want to travel in the longer boat you want. 

**Storage**

Touring boats will have much more storage in them as that's what they're meant to do. It's usually covered storage in the bow and stern of the boat. Sometimes SOT's have storage but most of the time it's sitting on top of the boat with you. Having gear on top of the boat makes it more accessible but easier to lose in the waves.

**Ease of Use**

SOT's are easy to use. Just sit on them and go. Touring boats take a little practice getting into and out of. A nylon or neoprene skirt to go around the cockpit and around your waist is a good thing to have in rough water or just to prevent drips from the paddle falling onto your lap. Using a skirt makes them a little more complicated to get into an out of though.

**Cost**

Touring boats tend to be longer and have more features so they'll probably cost you more. All the SOT's I've seen are made out of roto-molded plastic which is the least expensive to make. You can get touring boats out of roto-molded plastic, thermoformed plastic or fiberglass. Roto-molded is cheaper, heavier but very durable. Thermoformed is lighter and faster but more expensive. Fibreglass is the most expensive, the fastest but the most fragile. 

**Weather conditions**

Rougher conditions in the water will warrant a longer boat and probably one of the touring variety. The longer boats will be more stable and you'll be much more dry being inside the touring boat with a skirt covering the cockpit. 

Hope that helps.
I have been considering just the same. I have come up with two kayacks that I like. The first is a fishing kayak by kudo. It tracks well and speed is good. I have a strong upper body so it makes it easier for me but its all in the core. Try different techniques as you will get tired just doing one.

The other kayak is a 14 foot looksha by Necky. I have been eyeing that one for 3 years now. It is a sit in oh the kudo is a sit on top which I stood up in and tried paddle boarding on it. Great stability. The looksha tracks and maneuvers great.

Not stable enough for fishing, what are you going to do when you land the mother of all fishes? How you bring that into the boat? Consider what you do more spending time with the wife or fishing in a kayak?
