Step-by-step explanation:
An adjuster who specializes in marine losses is known as an average adjuster. This professional is tasked with assessing and handling claims related to maritime incidents, such as damage to a vessel or cargo. Their role is critical in situations when a ship sustains damage or loss, as they help determine the extent and financial responsibility for these losses. The term 'average' in this context refers to the maritime law concept of 'general average,' where all parties involved in a sea venture proportionally share any losses resulting from a voluntary sacrifice of part of the ship or cargo to save the whole in an emergency.
