HONAN MARU (POSSIBLY) - Nha Trang

The Honan Maru, or what we strongly suspect is her, offers a deep, moody dive that’s a real contrast to Nha Trang’s shallower reefs. Dropping to 46 metres, you’re looking at a proper technical dive, so come prepared with your certs and gas. It’s a huge old tanker, sunk in ‘45, and you can really feel that history as you descend into the gloom. We love the scale of this wreck. At 121 metres long, you can spend an entire dive just exploring a fraction of it, peering into vast cargo holds that are now home to schools of snapper and barracuda. The bow section is particularly intact and our favourite spot, often shrouded in a haze of glassfish. Visibility here can be hit or miss; on a good day, it’s 15 metres, but we’ve also dived it in 5 metres, which adds to the atmospheric, eerie feel. Look out for the resident moray eels that have made the collapsed superstructure their home. This site is for experienced wreck divers who appreciate a challenging, historical dive over colourful corals.
