Perhaps the top WW II wreck dive in Mediterranean, British Overseas Patrol submarine HMS/M Perseus, (N36) lies virtually intact on the sandy bottom, at 52 meters depth, about a mile off the south coast of Kefalonia.
Perseus submarine is not only among the most impressive wreck dives a diver can experience, but has an amazing history as well. The vessel was on combat patrol in December 1941, and while cruising at the surface at night hit an Italian naval mine and sunk. From the crew of 59 only one, the Royal Navy leading stoker John Capes managed a daredevil escape from a depth no one has attempted before, swam his way to Katelios and with the aid of locals escaped capture from Italian and German occupation forces and finally transferred in Turkey. While legendary in Royal Navy, almost nobody believed his adventure until in 1997 a team of Greek divers located the submarine and verified details of his described escape.
The divers approaching the submarine encounter a magnificent vessel 88 meters long, with a large conning tower, the ship’s gun and the rear hutch still open indicating the escape route of John Capes, while a look in the interior is possible. Among other things, the torpedo tubes and the ship’s propellers and rudder are visible.
The submarine is practically an artificial reef and colorful sponges, small fish and aquatic creatures take shelter here, while predators like amberjacks and snappers are frequent visitors.
The average depth or the dive is 40 m, while the max is 52, reserving the submarine for experienced and technical divers. The visibility is usually greater than 25m while temperature ranges between 15-25 C in summer months, depending on depth. Occasionally there may be strong currents close to the surface.
