A 16 ft 48" riveted jon boat with a 40lb trolling motor and 9.9 outboard is the most useful boat made with a reasonable weight for the money. Regardless of the rating given by the manufacturer some vehicles will tow better than others. The wheel base,brakes,frame, weight distribution,all play a factor with how surefooted a vehicle is with something in tow. Power is not the main problem...you can learn to tow even with a pretty underpowered engine. But...if the transmission does not have a cooler can be a problem on hot days or if the tranny is just not tough enough. And if you have a light rear end and two wheel drive you can get stuck on the ramp if the trailer drops off the end of a concrete ramp or the ramp is really slick and steep. Pickups can even do with some weight in back under certain conditions.
