Re: self loading boat
I believe he is referring to
THIS.
OK I watched it.
For one thing, I like the bow ladder and that would be a good thing to have in a number of situations. But not the rest of it.
The rest of the rig, unless you are handicapped or otherwise not able to manage a boat and trailer, seems unnecesary and problematic.
For launching: not needed with rollers; probably not needed with most floaters. And I've heard of people rigging a power winch to pull a boat back but that takes a lot of engineering.
For retrieve: a plain old power winch does what this does.
I don't trust the latching hardware; i want a simple strong hook-up I handle myself and visually check myself.
The whole thing looks weak. you pull the boat back on pulleys on side posts--see how long they last before bending. The electronics look weak. None of it would last long around salt water is my bet. If any of the components don't work you are stuck (you can hand crank a power winch).
Since it's designed for small boats it's hardly necessary.
File it under "too many things to go wrong" department.
I'll admit though my perspective is a bit different b/c around here, all ramps have docks next to them, so there's some advantage there for those who don't tight-rope walk too well.
