When people start kayaking, they generally look for a wide kayak because of its perceived stability. But as they progress, they find that a narrow kayak is better, more stable in rough conditions, and overall safer as a vessel for touring. There is a reason (and it isn't just that hard shell kayakers are elitist) that even though FolBoats have been around for much longer than hard shell touring kayaks, that hard shell touring kayaks are the preferred route of the vast majority of people on expeditions.

Perhaps you should start taking the kayaking classes now so you can get on water experience before you settle on the gear you will use.
