    The Marina T is a proper behemoth, a huge steamship that met its end during a tow in '79. We love how the sheer scale hits you straight away – 146 metres long, sitting upright and broken into two main sections. Dropping down, you really feel the history. The bow section is our favourite, with its massive anchors still in place, covered in a thick carpet of sponges and hydroids. Visibility here can often be a dream, letting you appreciate the wreck from a distance before getting up close. Swimming along the deck, you’ll spot grouper lurking in the darker corners and schools of damselfish flitting through the superstructure. It’s an open wreck, so penetration is generally safe and easy, but always go with a guide who knows the layout. We’ve spent hours here just exploring the cargo holds, imagining the life this ship once had. It's a dive that truly reminds you of the power of the sea and how quickly nature reclaims what’s lost. This is for divers who appreciate big wrecks and aren't afraid of a deeper dive; there’s so much to see, it usually warrants a second tank.
