The American Club is accused of terminating coverage of a troublesome ship controlled by George and Stathis Gourdomichalis to avoid having to pay an eight-figure claim, according to a new lawsuit in the ongoing Adamastos abandonment saga.

In the $18.5m lawsuit, Munich Re-backed Great Lakes Insurance has alleged that the New York protection and indemnity club and the Gourdomichalis brothers conspired to abandon the 73,500-dwt Adamastos (built 1995) after it was detained by Brazilian authorities in 2014.
