The T-Shirt Man Overboard Drill comes as one of the most important emergency drills at sea. The T-Shirt Man Overboard (MOB) Drill trains crew similar to how they should immediately respond when a person has fallen into water-position marking, keeping visual contact, and maneuvering the vessel as well as coordinated rescue.
Under SOLAS regulations, drills are for readiness, cooperation, and clear lines of command. Not one second but every second counts with defined roles for all the crew members. Repetition by drills brings about a state of preparedness that ushers in calm reactions, precise communications, and recovery operations when it matters most.
This T-shirt is awareness; it is responsibility; it is professional seamanship. It spells out the reality that MOB drills are not theory—they are practiced to save lives.
Created for seafarers, deck crew, and maritime professionals who know that preparation at sea is non-negotiable.
From crew, to the crew.
