Dona Marilyn Wreck: Exploring a Sunken Ferry in the Visayas

Approaching the Dona Marilyn Wreck, you'll see the distinct silhouette of a large passenger ferry emerging from the blue. This 98-meter vessel, the MV Doña Marilyn, rests on its starboard side, its structure remarkably preserved despite its sinking in Typhoon Ruby/Unsang in 1988. The sheer scale of the wreck becomes apparent during the descent, with the bow and stern still clearly defined, inviting you to explore its various sections.

As you get closer, the details of the ship's past life begin to reveal themselves. Decks, once bustling with passengers, are now encrusted with a vibrant growth of soft corals and sponges. Light filters through openings, creating a dynamic interplay of shadows and illumination within what were once cabins and common areas. This transformation from a functional vessel to a thriving artificial reef is a continuous process, evident in the intricate details found throughout the wreck.

The shallowest parts of the wreck begin around 17 to 18 meters, allowing for initial exploration of the upper decks. From there, the wreck slopes down to its deeper sections, reaching approximately 32 to 33 meters. This depth range allows for a multi-level dive profile, enabling you to spend time observing the diverse marine life that has colonized the different parts of the vessel.

Navigating the Dona Marilyn offers a sense of quiet reverence for its history. You'll find whitetip reef sharks patrolling the perimeter, while blue-spotted stingrays and blue-spotted ribbontail rays rest on the sandy bottom nearby. Schools of glassfish shimmer in the darker recesses, and sweetlips, scorpionfish, and batfish are commonly seen moving through the coral-draped structure.

The wreck is also a haven for smaller, more cryptic creatures. Keep an eye out for nudibranchs, frogfish, and flatworms camouflaged among the corals and sponges. Sea snakes are occasionally spotted, and cuttlefish can be observed moving gracefully over the wreck's surfaces. The presence of draped fishing nets in some areas adds to the wreck's character, serving as a reminder of its interaction with the marine environment.

Currents at the Dona Marilyn Wreck can be variable, ranging from mild to strong, and conditions can shift during the dive. This variability means that while the wreck itself is substantial, managing your position and planning your dive profile with the potential for current in mind is essential. Experienced divers will find this adds to the dynamic nature of the exploration, but it requires attention to detail and good buoyancy control.

For those with appropriate training, some areas of the wreck may allow for penetration. This should only be attempted by qualified wreck divers who are experienced in overhead environments and have the necessary equipment and gas planning. The intact nature of the wreck, combined with its depth and potential currents, makes it a site that rewards careful planning and respect for its environment.
