The Theros departed the Dartmouth yacht club June 11, and was last heard from June 13th. the vessel with 2 persons on board was due in the Azores on July 2. instead they were found, deceased, in their black dingy when it washed up on sable island July 10th.

Family reported them missing June 18th, after they received no further contact form the couple after the 13th. There was no distress call from the vessel, nor did it appear to carry an epirb.

There was a suggestion that the Theros may have been run over by a LNG Carrier Ineos Intuition. this was based on incomplete AIS Data for the Theros, but the last known position provided by the USCG suggests the Theros was well past the track of Ineos Intuition.
