Charlie. By surf, these models are referring to wave riding for fun. They are also made for someone a bit more "demure" than someone like yourself or me. Check out the max capacities of those.
The longer yaks do track better in rough water. Shorter is better for ponds, calm waters, rivers, etc.
Check out www.kayakfishingstuff.com
They have many different styles of yaks with good pricing and comparisons. they also have forums to ask questions. I'm just relaying what i learnewd from my research and by no means am I the consumate expert on kayaking. Just trying to help.
