Sure, this 465.8 feet long and seven stories high mega-yacht named the "Sunborn Gibraltar" would look great hitting the open seas, but it won't be doing that anytime soon. Situated in the land-scarce city of Gibraltar, it will be permanently docked at the Ocean Village Marina at the southern end of the Iberian Peninsula. With 189 beautifully designed rooms, private decks and plenty of cocktail bars and restaurants, you'll feel like you're at a Four Seasons with spectacular views more so than a place you could get seasick.
