I understand what your saying Whiskers about guiding and having someone trip and go overboard, then you are going to hit the button that says MOB for the first time ever. The setup works fine when me and Wilbur are the only one using them, they are very ultra light and comfortable for what i use them for. Whiskers i seen them single mast seats but don't know if they are sturdy enough for when folks start rocking on them. Good luck finding the setup that serves you best.
