Jeff said glass boats dont blow around as much. As far as walking around my 19' alum is 8ft wide, I can walk all over and not bother anyone, shakes my poles a lil though.
I just looked briefly at the pics, neither look fun for 4 growing people. I dont see much need for the extra inches and I would prefer a 150 to save some fuel over the 200. If I was paying cash I'd cheap out, if making payments I bet those extra inches are only a few more bucks. Are the compartments better in one or the other?
