I have what I call a ratchet winch - a very old small bulbous casting with a handle and chains coming out each side. I've used it in the past for lifting the engine out of a boat. I'd forgotten I had it but found it today when looking for parts of a scaffolding tower in the garage (poss question about that coming up later!).
I've been dithering about buying a high lift farm jack type device for a couple of jobs, one of which is pulling a boat upright on a trailer but I think this winch would probably do that job.. In the past we might have attached a rope to the Land Rover in low range, but the "children" are telling me we shouldn't be doing things like that these days and I need them to help as a second pair of hands/eyes.
My question is which device would give least danger and most precision in use. I've never used a farm jack, so I don't know anything about them. Are the cheap ones from ebay like
