Why dive here
With 113+ marine species recorded in the area - including great white sharks, hammerhead sharks, mobula rays (devil rays), octopuses and sea turtles - BO WOO NO.7 offers some of Jeju Island's richest wreck diving.
We've always had a soft spot for wrecks that tell a story, and Bo Woo No.7 is a classic example. Sunk in a storm back in '82, this old cargo ship now sits upright, mostly intact, about 30 metres down off Jeju's coast. When you drop down, the sheer size of it is immediately impressive. The wheelhouse is still there, eerily complete, and you can duck your head into the cargo holds, imagining the last journey. What we really love about this site, though, is how the ocean has completely reclaimed it. The deck railings are fuzzy with hydroids, and anemones burst from every crevice. Look closely and you’ll find nudibranchs inching across the metal, and we've often seen schools of yellowtail fusiliers swirling around the mast, so thick they almost block out the sun. It's a proper wreck dive, perfect for those who enjoy exploring the nooks and crannies of a submerged piece of history, rather than just admiring a coral garden. Just be prepared for potential currents; they can pick up, especially if you're planning a deeper penetration.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.

The story of the Bo Woo No. 7 is a stark reminder of the power of the sea. This Korean cargo vessel, built in 1956, was on a routine passage to Seoguipo on the beautiful island of Jeju in November 1982. While en route, the ship was caught in severe weather that proved too much for the 26-year-old vessel. Overwhelmed by the storm, the Bo Woo No. 7 foundered and sank off the coast, becoming another casualty of the region's unpredictable seas.
Information on the Bo Woo No. 7 as a dive site is scarce, adding a layer of mystery for intrepid wreck explorers. The official depth of 0 meters suggests the wreck may have been salvaged, lies in the intertidal zone, or is so broken up in the shallows that it is no longer considered a submerged hazard. For divers in the Jeju area, discovering the final resting place of the Bo Woo No. 7 could be a true adventure, requiring extensive local research and a keen eye to locate what remains of this vessel lost to the waves.
