I don't think you will find people going to Peru although you might find someone going to Ecuador, but much more likely from Panama than BC. As you might expect ocean currents, and prevailing winds pretty much dictate where you can go and when. Once you get much south of Panama you have the Humboldt Current coming against you all the way down the South American coast. You can push against until about Guayaquil but that is about it. Also there are precious few harbors or anchorages in Peru. If people want to do the coast of SA they would typically go to Easter Island from the Galapagos (a long way west but it gets you away from the Humboldt and is worth the visit). Then they would go to somewhere on the coast of Chile. From here you can go south towards Tierra del Fuego or turn left and go northward up the coast. Often in sailing, the shortest distance is not the fastest (or most comfortable) way. In total, the number of boats doing this is quite small. Not sure of the number but a guess would be 10 to 20 and most would have their crew arrangements in place.
Heading back to Lake Ontario for this summer. Ainia is back in North America for the first time since 2010. Currently in Long Island Sound.
