Choosing a kayak for me HELP!!!

width
Probably basing that notion on the tendency of SOTs to be wider than SINKs. Where you sit isn’t going to affect the draft of a boat. It’s purely bottom shape (flatter will be shallower), and bottom area (wider and longer will draw less).

Dagger Axis 12.0
I’m about your size and I am considering this boat.

gets great reviews.
