Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
The Grec, also known as the Sagona, presents a fascinating historical dive with a compelling narrative. This small cargo ship, originally built in Dundee in 1912 and later armed as a pinardier, met its end on December 3, 1945.
While carrying a cargo of wine, the Sagona struck a mine on its port bow within the Great Pass area, leading to its immediate sinking and the loss of three crew members. Divers exploring the Grec will find its wreckage in two distinct parts, separated by a few dozen meters; the central and aft stern sections remain upright on the seabed.
In contrast, the bow section is heavily dislocated, telling a vivid story of the explosion. The site is notable for its close proximity to the Donator wreck, having sunk in a similar manner and just 23 days apart, only a few hundred meters away.
While sharing many characteristics, the Grec's orientation differs, with its remnants facing Port-Cros. This deep wreck, sitting at 48 m / 157 ft, requires advanced diving skills to fully appreciate its structure and historical context.

Dive Experience & Conditions
The Grec (Sagona) wreck's structure reveals its violent end, split into two major sections; the central and aft parts stand mostly upright, offering a clear profile of the vessel's stern to explore. The bow, conversely, exhibits significant damage and dislocation, vividly illustrating the mine explosion that caused its demise.
