From Kerzo to La Biche

From the foreland of Kerzo to La Biche. The most popular beach (easy of access) is Port Andro. The small creek of Port-Billon, located near Port AnDro is very well protected from the westerly winds. The beach of "Les Galères" is only accessible when the tide has small coefficients.

QUIZZ - Concerning the beach of Les Galères, there is one question: on some maps of Belle-Ile (as the map of Pierre Gallen, published in 1992, for ex.) there is one place named "la chaudière" (the "steam boiler") just on the North of the beach of Les Galères, on the small cove of Porh Enn (see the map below). At this place, by low tides, you may see a wreck which seems to be a ship steam boiler.
Here are some photos of this wreck and of its location :

Apparently, no ship wreckage has been noticed at this location: see the list of the registered wrecks in the area (the nearest wrecks are the cargo Kansan and the cargo Ruytenf Jell). Could it be a part of one of these wrecked ships driven ashore by sea currents ?
The pending questions are :

Is it really a ship steam boiler ? (or a condenser ? or a part of boiler ?)
If it is a steam boiler, where does it come from ? a ship ? (it does not seem to come from the land: there is nothing above, except the moor...)

MYSTERY... If you have some information, we would be pleased to get it; thank you by advance !
