VESSEL TYPE DESCRIPTION

The Melissa Desagnes is categorized as a motor vessel (M/V), a type of powered ship designed for transporting cargo or passengers. Based on its classification as a dangerous submerged wreck, the vessel likely encountered an incident severe enough to render it inoperable, leading to its grounding and eventual submergence near Grassy Island.

HISTORY OF THE WRECK

The M/V Melissa Desagnes was reported grounded in Local Notice to Mariners (LNM) 38/1997 by the U.S. Coast Guard District 9.

The wreck was later officially documented in the Canadian Hydrographic Service (CEH) database in May 2008.

The lack of details on the cause of the incident, the year of sinking, and the circumstances leading to the vessel’s grounding leave the story incomplete. Additional historical records may shed light on whether the vessel was lost due to navigational error, mechanical failure, or adverse weather conditions.
