@Rockin Robbins:
Say, that's a neat Astro/solar sys sim.
However, I don't see any navigational difficulty with 53°54.6'N x 166°31.9'W (Dutch Harbor) anymore than I would with 59°32.5'N x 001°37.3'W (Fair Isle, Scotland, UK) in the Orkney-Shetland gap. I've not sailed the North Pacific, but have been in the North Sea. I can imagine it has it quirks, hey?
