I have a 14'11" long and 48'' wide heavy jon, and two men of my weight(200) can climb up on the side and jump up and down and never come close to tipping it over. I have had it on Kentucky and Barkley lakes in three and four foot whitecap waves and made it home safely. But I durn sure did not like it, I would not have liked it in a barge. The only drawback I see is the flat front rides like a log wagon in choppy water. If one with a modified vee front end was available, I would look at that if you intend to ride comfortably in choppy water.
