Bianca C (Wreck)

Bianca C, known as the "Titanic of the Caribbean," is the largest diveable wreck in the Caribbean. This magnificent wreck was once a cruise ship belonging to the renowned "Costa" line. Tragically, in 1961, a devastating boiler explosion and subsequent fire led to its sinking as it prepared to depart.

Divers exploring the depths of Bianca C will be greeted by an awe-inspiring sight. With depths reaching up to 30 meters (100 feet), this dive site offers a mesmerizing encounter with barracudas and mesmerizing schools of horse-eye jacks. The shallower parts of the wreck boast a vibrant display of coral and sponges, adding to the enchantment of the underwater world.

The letter "C" in Bianca C represents the Costa line, paying homage to its origin. Interestingly, the ship was named after the owner's daughter, Bianca. As recreational divers embark on their adventure, they can marvel at the upper levels of the wreck, keeping a watchful eye for the graceful eagle rays, swift barracudas, and the occasional appearance of the horse-eye jacks swimming in harmony.

With a seabed resting at 50 meters (160 feet), the Bianca C wreck offers an exhilarating experience for advanced divers seeking a tech dive. The multi-level profile allows for an extended exploration of the wreck, with the opportunity for staged decompression before ascending to the surface. Although penetration into the wreck is not advisable due to its condition, divers will find delight in the intriguing swim-throughs that the site has to offer.

Located in Grenada, the Bianca C wreck is a testament to the rich diving opportunities found in this Caribbean paradise. With a visibility of 19 meters and a maximum depth of 38 meters, this dive site promises an unforgettable underwater excursion.
