There are probably more Robert Allan-designed ship docking tugs under construction world wide than any other design. So it is not surprising to see one under construction at the Estaleiros Rio Negro Ltda. (ERIN Shipyard) in Manaus, Brazil. It is undoubtedly the only Rampat 2400 being built in a yard1000 miles from the sea. But then Manaus, like so much of contemporary Brazil demands superlatives for accuracy. The first of three Rampart 2400 ship docking tugs under construction at the yard is showing the distinctive Robert Allan Ltd. lines.
