We use GeoBlue for personal travel health insurance outside US. They cover all expenses, repatriation, etc. And seem pretty comprehensive. We have never had to use it. You simply get on their website, give them your travel dates and some simple information and you get a quote that you can bind online.
However all of this assumes that you are a US citizen and have US health insurance for the US.
We also have DAN boater insurance that is a very good value for extreme situations.
