RMS Scotia, wreck

The RMS Scotia, a British passenger liner operated by Cunard Line, once held the title of the fastest westbound transatlantic voyager. Initially a paddle steamer, it was later converted into a twin-screw cable layer in 1879.

This dive site is teeming with a diverse range of reef fish, including frequented by White-tip and Black-tip sharks, as well as Green Sea Turtles.

Having served its role for 25 years, the RMS Scotia met its unfortunate fate off the coast of Guam in 1904. Today, the wreck is submerged in 30 feet of water and scattered across a sprawling 100-yard reef, providing a fantastic diving experience in crystal-clear waters. However, exercise caution to avoid drifting into the shipping channel due to potentially strong currents. It is advisable to coordinate with your boat captain for a safe dive.
