My wife and I have used closed top Sea Touring kayaks for the last 20 years to fish in the New Mexico lakes.
We went to San Diego and spent some time at Southwest kayaks. We took their safety classes to learn all the rescue techniques and then tried out different types of Kayaks to see what would work for fishing.
We ended up going to Seda Kayaks and buying two of their "Gypsy" models which are 15 ft fiberglass with 24' beam so they are very stable. These also have enough rocker so they ride over the waves instead of crashing through them. In other words you can surf in these kayaks..
I use a spray skirt only in winter when its cold and a wet suit just in case.
My wife and I have never rolled these and I have been out on a lake with 70 mph winds. Scary but
the kayak handled great.
Most Sea kayaks have sealed bulkheads front and rear for dry storage and to prevent the kayak from sinking if it fills with water.
I use the Yakima soft kayak saddles to transport since these have thin fiberglass hulls to keep the weight down.

I would love to get their "Glider" which is one of the fastest kayaks for distance racing...

Since you are in Georgia which has a coastline there should be lots of kayak shops where you can try out or rent different models to see what works best.
Buy some kayaking magazines and see what is out there before spending your money.
And by all means take a safety course to learn "Self rescue" and "Buddy rescue" techniques.
