Their are many myths on ship wrecks and the Hirondelle is one of them. This wreck lies of the coast of Vevey (pointe de la Becque) in Switzerland, in the Lac Leman. It's deepest point lies at 58m. This dive is the reward for the hard training the local divers endure in order to pursue this wreck. It's not just the depth, but the whole environment that causes trouble. Usually during the first 40m of the dive, the visibility is down to a few centimeters and their is no line to reach this wreck; it's a shore dive! The temperature of the water is only just a few degrees above 0 and their can be some current.
The bow is reached in 42m and the stern is down on a steep slope at 58m on a bottom composition of thin silt. The wreck is broken at 2/3 from bow at the level of the funnel and some local divers claim that the stern part lies further down, off the cliff that drops all the way down to 110m. The object of this dive was to check this out against history that claims that the stern never sunk !!!
