Is it a house with a deck or a ship by a dock? This enormous coastal retreat is shaped like the bow of a ship with an ultra-wide deck and a bridge jutting out to the sea. Lounge at its point, dip in the infinity pool lined with charcoal-black volcanic lava stone, play ping pong, and hit the wet bar en route to a sunken Zen garden. A 5-minute buggy ride gets you to golf, tennis, shops, and a spa.
