Map route, specifically across oceans without zoom gimmicks

I’m looking to describe our passage by boat across oceans, calling in at ports and harbours, so I’m after a customisable map (or nautical chart) that will show proposed routes between countries across oceans. Ideally I need to split the animated line to show two possible routes. For example, I want to show going from the Philippines up to Japan by sea, and then two routes splitting, one going to Canada and one to Hawaii. I don’t really like the zooming in and out where you get taken through clouds and into space, I’d prefer to show routes from, say, airplane height or lower.

Any recommended AE kits out there that fit the bill?
