It's a mega yacht. With a built-in lagoon. Called the Tropical Island Yacht, this giant 100 million dollar boat from Yacht Island Designs features a volcano waterfall, which flows as a stream into a tide pool, then into a lagoon pool.
Over-the-top tropical floating island is a fantasy dreamed up by Yacht Island Design, which planned it as a private luxury yacht to accommodate 10 guests with about square feet of usable space. I want this!
