Easy,
These are the boats I looked at before I bought mine. I decided on a slightly heavier guage aluminum hull (welded). I ended up with an open 16 foot Harbercraft. Its a solid boat and handles the rough water well. I looked hard at the Valco's and Klamath's as well, but wanted thicker guage metal all the way around.
