I know they rate the boats modestly to prevent any lawsuits but you still need to take it into account. My Dad has an old 11ft Jon Boat coded for 380lbs but that again is a modest rating. Napa and I have taken it out numerous times- 2 * 190 pounders, 2 batteries = another 100 lbs and gear/anchor = 50 more pounds (total around 550lbs). We have not had any issues thus far but definately need to use additional caution when manuvering. I would recommend between a 12-14 ft jon boat for him especially if he's a big guy and wants the ability to have company in the boat.
Roger and I have proved without a doubt, the boat weight limits are just suggestions. lol
My buddy is trying to figure out what he wants for a boat that he can car top. He's kind of a big guy. Some of you have seen him at tourney's with me. So he's looking at a 10 jon at BPS and it says
max weight 320 pounds
max person weight 280 pounds
He reads it as maximum is 320 and I read it as combine the two for 600. Anybody know which is right?
