    Marmer is probably our favourite wreck on Tongatapu, not for its depth – it’s only two metres, barely a duck dive – but for its sheer, defiant character. This tug went down in a storm back in '82, a rough day by all accounts, and she’s stayed put, stubbornly half-submerged just off the coast. You’ll spend most of your time with your head bobbing above the surface, then dipping down to explore the wheelhouse, which is surprisingly intact, or peering into the engine room. The wreck itself is a tangle of rusty steel, a dangerous wreck for sure, but that’s part of the charm. Sunlight spears through the gaps, illuminating schools of tiny glassfish that shimmer like scattered jewels. We’ve seen juvenile batfish here, curious and bold, along with plenty of parrotfish scraping algae from the hull. It’s a photographer’s dream, especially on a sunny afternoon when the light is just right. We’d suggest going at high tide; it gives you a bit more room to swim over the deck rather than having to contort yourself around the exposed bits. If you love a shallow, sun-drenched wreck with a bit of history and a lot of personality, Marmer is absolutely worth the effort.
