I like bunks as others have said If you have bunks and they are installed correctly you won't ever be that (propblem) guy.
I have a 17ft boat with bunk sliders and even on a shallow ramp loading/unloading isn't really a problem. You need to crank hard loading on a shallow ramp that is true and sometimes I need to use the reverse and brake method to kick the boat off when launching but it works well even by myself.[/QUOTE
Yep... and if it's a little shallow, just power the boat on to the bunks (if the marina allows that.) Otherwise, on most ramps float on, float off, quick and easy - hardly ever need to crank the winch more than 1/2 a turn, strap 'er down and we're gone.
