Simplified Wreck Survey
Underwater Wreck Details: The GYLLER wreck is an identified maritime obstruction located off the coast of Brittany, France, near the Le Four lighthouse. The wreck is situated at coordinates 48 31.416 N, 04 48.305 W. Historical survey records indicate the vessel has a general depth of 5 meters and an approximate size exceeding 50 meters or 1000 tons. While the wreck appeared on various French hydrographic charts over the decades (including French 7122), subsequent investigations by SHOM (Service Hydrographique et Océanographique de la Marine) noted that the GYLLER lies in close proximity to another underwater wreck. Due to overlapping survey data and scale limitations on nautical charts, its status has been subject to multiple updates, with recent assessments classifying the wreck as deleted or removed from active navigational charts. Mariners should note these coordinates for historical context and awareness of potential underwater obstructions in the vicinity of the Le Four maritime area.
