It's pricey (like all Harken stuff) but very nicely engineered. We see them on display every year at Canoecopia and it's pretty much just a matter of pulling one line (one-handed will lift most canoes) and watching the thing go straight up or straight down with all the support lines pulling evenly. No tilting, no wobble, locks preventing accidental dropping, etc. If you're willing to spend the cash, I don't think you can beat it for ease and convenience (it's also pretty tough to beat it, price-wise, by cobbling together a copy unless you happen to have a bunch of small ball-bearing sailing blocks and cleats sitting around). I put together a somewhat similar lift to install and remove the hardtop on our T-Bird, just using a webbing harness and a couple of good fiddle blocks. It works OK, but even so, the blocks, rope and cleat are worth about $90 and it doesn't even approach the hoister in terms of resisting tilting, spinning, etc.
