complicated piece of engineering, what's so difficult with a rocker and two ockie straps and you can throw away your rope as well .

It's certainly better than no catch at all but having to pull a piece of string is a poor design I think. It appeared the string had to be pulled quite strongly and I'm guessing that will become more so as more weight is on the catch. Imagine someone wrapping the string around their hand so it doesn't slip then when the boat releases, no being able to let go quick enough. Would just about rip their arm off. I just did a DIY version of the Bar Catch or Catch N Release type mechanism. Simple, reliable, and no long length of string.

Very ordinary presentation, yes it works as you say, how about telling the rights and wrongs of launching and retrieving, you need an extra person to drive the boat away from the car and vica versa, a half hearted marketing video wont get you too many sales. Therefore thumbs down.

So you let go of the string..and the driver has to get put of the car and retrieve it. ...or leave it there and run over it.. Shitty design
