Cruise Singapore's waters on a Lagoon 400. The sailing catamaran, which comes with double hulls, is well known for its stability and is perfect for guests going yachting for the first time, as well as groups with children and the elderly. Sail to the Marina Bay Financial District for a view of the skyline, then head to the Southern Islands where you can lounge on sandy white beaches and go for a swim in clear waters. Depending where you'll anchor, you'll also get the chance to snorkel or dive up to 70ft under water. It's the perfect breather away from the city - aboard a deluxe yacht, no less.
