pilot boat is a type of boat used to transport maritime pilots between land and the inbound or outbound ships that they are piloting. Pilot boats were once sailing boats that had to be fast because the first pilot to reach the incoming ship

That speed was approximate 3 ship lengths to the pier and there was the on pier wind after the turn. Why the ship entered the port so fast will be the subject of the investigations to be awaited. Knowing South Korea procedures there will be no just marine...
