From their website, it seems a lot of thought was put in to the location they chose, for many of the reasons I outlined in my post above. Ocean Builders have recently made a blog post which states that they are keen to stay within the Andaman Sea due to its calm waters and lack of storms and hurricanes. They also state they have received offers from other countries who would be keen for them to set up near their coasts.

It very much looks like they are keen to push on despite this setback, so kudos to them. It also looks like they may not have to move very far from their current location to find a new and more welcoming home.
