What’s the difference between a touring kayak and a recreational kayak?

I live on the Hillsborough River in Tampa. I’d mainly like to get a kayak for going up and down the river. There’s a riverside bar/grill I like, plus I have other friends that live on the river. But also, I’d like to be able to take the kayak into the Gulf of Mexico sometimes. Being able to fish from it would be nice, but not a priority. Any suggestions?
Jim, what are you, a hooker?
