Gentlemen.
I know that this is slightly off paddle ships, as such, but I found this a
very interesting site.
Click on here http://www.pancanal.com/eng/index.html to see the ships
actually working through the canal at the Miraflores Locks. Many of the
ships seem to only just fit through the locks, with almost no clearance. The
Eppleton Hall on the other hand must have looked very small indeed when she
sailed through.
It says it updates very 10 seconds, it doesn't quite do that, but not far
off. The camera gets moved to look at different views at various in
specified times.
All the best and happy paddling.

Best regards
David

Thanks for the link David!! -I've just spent an amazing half hour watching
a crude carrier being lowered in the lock - at night - stunning!!!!!
