The Site

HMS Nasturtium was a Flower-class corvette lost in Maltese waters during the Second World War, and today she's one of the island's finest deep wrecks, sitting at around 68m. Largely intact and rarely dived, she's a genuine technical objective — Trimix 75 territory — with the atmosphere that only a deep, quiet, complete warship can offer.

Train for This Dive

The diving here suits divers at Trimix 75 level. If you’re not there yet, these are the courses that get you there:

Advanced Wreck belongs on this list too. It isn’t what raises your depth limit — your gas qualification does that — but it’s what makes penetrating a wreck at this depth a sensible thing to do: long line work, losing the line and finding it again, and out-of-gas contingencies inside an overhead.

Already certified and just want to dive it? Come and explore it with me on open circuit or CCR — one relaxed dive a day, no rushing, as long in the water as you like.
