I like my Grizzly jon boat but would caution anyone to get one thats too long 17ft or bigger cause they will beat you to death. Mine is a 14 ft version and it doesn't go fast but it is stable.
I guess if all add ons are welded it won't sound or feel to bad but if all they do is rivet decks or consoles then your gonna chatter everytime you hit a wave....gets kinda loud.
