ALPHA COMMANDER - Diani Beach & South Coast
The Alpha Commander is one of our favourite wrecks in Diani, a proper old trawler that went down in 1980 after a run-in with something big and unseen. It sits upright at 25 metres, and you can see the sheer scale of it as you descend, the deck guns (or what's left of them) looming out of the blue. We love poking around the engine room, picturing the chaos when it took on water. It’s a fantastic site for advanced open water divers who appreciate a wreck with a bit of history and a lot of character. Expect to see schools of snappers schooling around the bow, lionfish tucked into every crevice, and the resident moray eels peeking out from behind corroded bulkheads. The hull is completely encrusted in colourful sponges and soft corals now, a real contrast to the rusty metal. We'd suggest getting there early in the morning before any stronger currents pick up, which can sometimes sweep across the deck. It’s a proper dive, one that leaves you thinking about the stories it could tell.

The Alpha Commander was a hardworking trawler plying the rich fishing grounds off the coast of Kenya. On September 23, 1980, while on passage back to Mombasa, its journey came to an abrupt end. The vessel struck a semi-submerged, unidentified object just three miles off Mtwapa. The impact holed the engine room, and despite the crew's efforts, the sea rushed in, sinking the trawler and sending it to its final resting place on the sandy seabed.
Today, the Alpha Commander sits upright at a depth of 25 meters, making it an excellent and accessible wreck dive for advanced divers exploring Kenya's south coast. Over the decades, the Indian Ocean has transformed the steel vessel into a vibrant artificial reef. Schools of snapper and glassfish swarm its superstructure, while moray eels peer from pipes and lionfish hunt along its decks. The wreck is a fantastic opportunity to explore a largely intact vessel and witness how nature quickly reclaims what the sea has taken.
