    CharacterWreck dive

    The HMS Starfish is more than just a lump of metal on the seabed, it’s a sombre reminder of wartime history, and we think that's why it holds such a draw. This S-class submarine, sunk in 1940, rests upright, largely intact, which is remarkable for a wreck in these waters. Descending through the North Sea’s often green embrace, the sheer silhouette of the submarine emerges, a dark mass against the sometimes murky backdrop. We love exploring the conning tower, imagining the cramped conditions within. Look closely and you will spot common whelks navigating the plating, while scaldfish often dart from the shadows of a torpedo tube. The wreck itself acts as a massive artificial reef, attracting poor cod and whiting, and we’ve even seen common seals make a curious pass or two. Diving the Starfish often means contending with a bit of current, so it’s definitely one for more experienced divers. Pick a day with good visibility, if you can, to really appreciate the scale of this historical site. It's an imposing dive, certainly, but deeply rewarding.

    Safety Notes

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

    Cold water this month (avg 13°C). Drysuit or thick wetsuit (7mm+) recommended.
