I don't know if a one man is any more or less stabile than a 2 man, but I don't think that is an issue. I have hunted out of MLB Classic when a 20' sea ark flat was heading in because IT was taking on water. If the MLB will not do it... I will not be out anyway. The hard part for me is the Pain inthe #### that a two man is. Towing vs putting in the boat... going down the road.. Many set ups aren't condusive to trailering with the two man layout in the boat, (or they are just to darn heavy to lift into the boat... If that is the case, you need another truck and trailer to get to the launch. I woul d100 % of the time prefer 2- 1 man layouts (MLB's) to a 2 man of any design.
