For the world's largest cruise ships, arriving to St. Thomas in the Caribbean can be daunting. Narrow waterways, sailboats anchored in the harbor, a tight turn and a relative small amount of clearance below the keel make the water around this popular port is one of the most difficult to maneuver.

But thanks to an expert marine team using state-of-the-art technology, arriving is just another day at the office for the crew of the 1,187-foot Oasis of the Seas. With a local pilot offering his expertise on the currents and local marine environment, and powerful bow thrusters which gives the captain the control he needs, it is nothing but smooth sailing for one of the world’s largest cruise ships.
