Wilhelm Heidkamp

The boat moors to a small plastic buoy attached to the Wilhelm Heidkamp, and the line brings you down onto the roof of her control room. She is the middle of the three destroyers lying off Framnesodden, on her keel with the stern blown off, and the group makes a fine and well preserved site between 12 and 24 metres — shallow enough that gas, rather than decompression, is what sets the limit.

From there, swim straight out from the Heidkamp's starboard side and the Anton Schmitt is about 7 metres away. The three wrecks lie close enough together that a practised diver with plenty of air can visit all of them on one dive without needing decompression, with the Diether von Roeder completing the set. Work them in order and come back up the buoy line rather than trying to relocate the boat from the far end of the group.

The trio was closed to divers until a few years before 2005, when local accounts describe them as recently opened, and they sit inside the harbour permit system. That means registering with the Narvik harbour board and signing the diving declaration before you go: the permit covers Wilhelm Heidkamp, Anton Schmitt and Diether von Roeder along with the harbour's merchant wrecks such as the Neuenfels.
