Hi, I have not had good luck with inflatible kayaks. They do not paddle and track like a hardshell. I suggest you get a "real" kayak like the Ocean Kayak Prowler 13 or Scrambler XT. These have much more universal capability. They are more challenging to learn to use perhaps but will in the end make you happier. If you really want to go for the "gusto" a Scupper Pro TW is a fast boat. Look at Cobra brand kayaks as well. They make some similar models that are just as good or better than the Ocean Kayak models I mentioned. Look at some of the older threads here for links. There are several websites that have info on kayak diving, if you cannot find them I will try to post a links. N
