The first sentence makes no sense, therefor i agree with the second sentence that you cannot be educators. You have nothing out there right now, i suggest again you do not buy an island as the very first action. Talador has been out there, if buying a pile of rocks was the best idea, don’t you think he and his friends would have done so by now? Investors aren’t going to buy it for you, because when you fail they will be unable to sell it and recoup their money. They must assume you will fail, because you have no proof of your points of success. You have not so much as spent a night out there, or sold one cup of coffee out there. On the other hand, of all the yachties who have been there, of all those who have lived on the islands, no one lives there.
You build your own seastead, not other people’s seasteads. If they are self sufficient, they can and will arrive in their own transportation and living spaces. The best you maybe can do for your dream is a support business and maybe eventually a hotel.
There, you said it. Your clientele will be unscheduled transients. You cannot build a harbor, that means dredging and filling, the opposite of “environmental stewardship” repeatedly mentioned in connection with Marinea. And Bahama won’t allow it. And they won’t allow the amount of ground tackle required for a workable floating breakwater. And, Route 66 was famous for people going places, what data do you have for the Cay Sal Bank being such a traffic route? And have you traveled Rt 66 lately? People found other routes to travel, virtually no one had any reason to stay encamped along the way. It took three days to travel the length of Rt 66, it doesn’t take that long to travel to Cuba, travelers’ support systems in Cay Sal isn’t required.
Start small. Gather data. You cannot sell things, to provide Ellmer’s dear ROI, without knowing your customers.
You go in and decimate the environment with large facilities and Bahama will declare the Bank a national marine reserve and kick everyone out of it forever. Cay Sal Bank is a geat place to start, but you can no more seastead the bank in a large way than the Great Barrier Reef or Chesapeake Bay or Minerva Reef.
