Sorry, it wasn’t meant to be sarcastic, I just thought it was a funny, if silly, solution to the problem you’d presented. I think that route has actually been done in the past, so I didn’t think it was too far out of line.

In answer to your question about sailing the Atlantic and the boat sizes needed, it looks like a cruising yacht culd do it in somewhere between 15-30 days, so you wouldn’t need a particularly large ship, but you’d definitely want an experienced crew.

People need these sorts of craft moved across the ocean every so often (when they’re being delivered to their new owners for example), so if you trained as a crew member you might be able to get a berth on a trip like that, arguably reducing your footprint even more.

Once again, my appologies for the way my previous post came across, if was not meant like that.
