Boris Wreck, Sal: exploring a Russian fishing trawler

The Boris, frequently referred to by its original name Kwarcit, lies on the seabed off the coast of Sal. This Russian fishing trawler sank in January 2006 and has since transitioned into a stable artificial reef. Unlike many wrecks that settle on their sides or break apart, the Boris remains sitting upright on the bottom. This orientation makes the structure easier to navigate and provides a clear profile for divers approaching from the surface.

The dive profile is relatively shallow, with the deck of the ship positioned at approximately 23 metres. The hull descends further down to about 28 metres, providing a compact depth range for the entire site. As you descend, you will see the vessel resting on the sandy bottom, with the structure acting as a focal point for much of the surrounding marine activity. The transition from the deck to the deeper sections of the hull is gradual enough to allow for controlled buoyancy adjustments.

For those with the appropriate training and experience, the wreck offers specific points of interest through its internal structures. The bridge and the holds are penetrable, though access is strictly dependent on the assessment of your guide and your own comfort level. Entering these spaces allows for a closer look at how the vessel has integrated into the local ecosystem. Careful attention to your gas management and exit route is necessary when moving from the open water into these confined areas.

The wreck has become a highly active habitat for various resident species. You will find groupers patrolling the structural openings and various nudibranchs attached to the metal surfaces. The seabed around the vessel is also a frequent site for stingrays to rest. These organisms utilize the wreck as both a shelter and a hunting ground, making the immediate perimeter of the ship a productive area for observing bottom-dwelling life.

Marine life behavior at the Boris is closely tied to the structure itself. Frogfish are often found camouflaged near the wreck, while nurse sharks make occasional appearances throughout the site. The presence of these larger animals is not constant, but the wreck's presence provides the necessary cover that attracts them to the area. Watching how these predators interact with the artificial environment provides a clear view of how the vessel has settled into the local food web.

Approaching the site requires a standard boat descent from Santa Maria, which is roughly a 15-minute transit. There is no permanent mooring or fixed line at the wreck, so you must be prepared for a controlled descent in open water. Maintaining good trim is important to avoid contact with the structure as you settle into your depth. Once you reach the deck, the wreck provides a solid reference point for the rest of the dive.
