    The HMS Sturdy is just… different for Komodo. Most of our favourite dives here are all about the ripping currents and the schools of pelagics that come with them, but Sturdy offers a slower, more contemplative dive. It’s an S-class submarine, sunk in 1943, and she lies mostly intact on her port side. You can still make out the conning tower and the torpedo tubes, all draped in soft corals – a vivid purple and orange against the dark steel. We love drifting along her deck, spotting the resident lionfish tucked into crevices and the curious batfish circling the bow. It’s a genuinely evocative dive, a moment of quiet history in an otherwise frantic dive region. Visibility can vary, but we find the best dives here are typically early morning, before the day boats crowd the area, when the light filters down softly onto the wreck. It suits divers who appreciate history and don't mind a slightly deeper profile.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
