Make Money While Cruising - List

[Agility]

I'd like to create an exhaustive list of how folks who are deeply passionate about cruising have also found ways to make money while cruising.

Here a quick list to start us off:

1. Writing books
2. Editing magazines
3. Charter own boat
4. Software development

Let's try not to include, sail a while then work a while, but how can you make money while sailing.

Keep the list going so the next idea is number 6.
