Looking to make a pulley system off my balcony to lower a 16'3" canoe. Or was wondering if I could purchase something to do the trick.

Harken makes good lifts, but I prefer to make my own. Since the demise of Webshots, my best photos of the pulley system I use are gone, but an example that's pretty close to my normal method is illustrated here (but the steel legs you see for supporting the canoe brackets when the rig is lowered is just a convenience feature):
Note that Harken recommends four-point lifting for canoes, but an easier method, and one which won't get misaligned due to rope stretch, is to support the canoe upside-down on bars, with those bars having a "wrap-around" feature that allows each to be lifted by a single rope. Some of the photos in the link provided show how to make such support bars.
You can eliminate the need for lots of pulleys by using a light-duty hand winch. You can get them for about $12 from Northern Tool, and models ranging from $20 to $25 are usually available at hardware stores.
The method I use relies on a single rope that's taken up by a hand winch (the system shown in the photos uses two ropes wound onto the winch, but that creates a problem which is described in the text that goes with the photos). That rope splits into two, with each fork passing through a separate lifting pulley. Each of those lifting ropes carries one support bracket of the kind I described above (two support brackets carry the boat). The only "rule" to follow is that when the main lifting rope splits into two, those two ropes must be fairly close to parallel. If they split into a wide "V", you'd need some additional pulleys to insure that the boat remains level during the whole phase of lifting, but in most situations it's easy to avoid the need for a wide "V" orientation of the lifting ropes.
If your store-bought pulleys use an aluminum rivet to support the pulley wheel, replace the rivet with a bolt or someday the rivet is likely to break and the pulley wheel won't turn.
Harken uses good-quality pulleys, but they are very tiny which means the rope must be very small diameter too. I'm not sure I'd expect such thin rope to last through as many seasons of outdoor exposure as something like 3/8ths of an inch or so. In either case though, replacing the rope at intervals is probably a good idea.

Yeah, good points|

Maybe this is just a transport system to get the canoe in and out of the house by a route that avoids use of the stairs. That's a whole other issue than the situation I addressed in my post, but actually a lot simpler to deal with. But like pilot says, the details about how to build it still depend on the layout of things.

Thank you for the suggestions. I took a second look at the structure of the balcony and im unable to use a pulley system. Im just going to have to rough it, and use the stairs :(.
