Gee, you *sailing* around Cape Horn and all you worry about is a -visa-?

Ok, I'll see what I can do; give me a day or two from monday.

Edited to add: I was lucky and got a very quick response from SCL. You don't pay the visa. Just go into the transit lounges at PUQ & PMC, which are before immigration, and that's it, easy. My contact in SCL added that for this to work well when you check-in at USH you should get your SCL-NZ boarding pass, and check your luggage right through, beyond SCL, of course.
