If you go with a 16', go with a boat that's designed for fishing from the ground up. I just bought a 16' Jetcraft Falcon. I've had larger boats and smaller boats. The small 14' scared the heck out of me one late afternoon in 4 foot mixed waves. My18 was a deep V and needed too much water to launch easily and I was restricted from getting into low water when I wanted to.
The Jetcraft Falcon has a 12deg dead rise with a delta pad and a 80" beam. I looked at all the others out there and the Jetcraft was the only heavy gauge all welded aluminum boat that allowed me to rig it the way I wanted it. The price is right there with the others but theres none of the pretty stuff on this boat. It comes in both a 16 and a 18 but after looking at both I decided the 16 was fine for me. I fished 4 in it last weekend and it performed beautifully.
Oh yeah, last weekend I loaded it faster than the kid with the Jet Ski next to me.
