I used to work at a yacht club on this island. These vacation homes were owned by the super wealthy, who had yachts, big ones. The big thing was to have lots of toys on your yachts. (Jet skis, little motorboats you’d launch off, etc.).
I found the big yachts disgusting, a huge waste of fuel and rude to other people in the waterways.
The superyachts to me are just gross. It is inevitable such a large vessel will harm the ocean.
