For simplicity of keeping the rope and pulleys organized, I'd suggest a fiddle block set.

Thanks PT. Andy, great post and very helpful - thanks. I like the Skywinch idea (share your thoughts that it's a windlass in a bracket at the end of the day) but I've got loads of suitable 12mm braided rope and it does look a neat solution in the way that it's just a case of using one handy rope from boat to car (no PITA steel cables) that can can be slotted in at any point and doesn't wind up on a drum.

Not sure what the mechanical advantage or effective effort required is though, do you know how this is calculated for a winch?

Sky winch looks like a simple solution.

Another option would be a self tailing winch from a yacht. Mount on a base plate that can be secured to the LR. Expensive new but often cheap at boat jumbles.

You dont need a huge capacity winch with the weight you are trying to move.

I like the idea of the Skywinch, but rope of the type suggested by the manufacturer has a huge amount of stretch and you will be winding for a long way before the boat even starts to move.

I would go for the KIS solution in manual mode. I use one of these occasionally, it works well and does what it says on the tin.

The length of the handle (from the axis of the drum to the grip) divided by the radius of the drum where the rope passes round it.

(If there isn't any mechanical reduction gearing involved)

Thanks Hugh, much appreciated - what is typical? I don't have any to measure...

How about one of these?

Admittedly not a budget option but would do the job well.

I just use a standard winch that i bolted to an old large ring spanner that simply hooks over the tow hitch on the car .
Wire is stainless steel plastic coated similar to yacht rigging wire but this stuffs from an old 300 ft radio mast .
