During my pilot trip I saw the boatmen of ‘De Koperen Ploeg’ (the Copper Gang) at work. Especially in dark it is impressive to see how the small boats are maneuvering. Their job is to moor and unmoor the vessels in the Port of Amsterdam. The boatmen are not merely throwing line around a bollard, but it often involves careful planning which, without the proper knowledge and expertise, could be extremely dangerous. During the mooring of the bulk carrier ‘Yeoman Bontrup’ the boatmen have difficulties to find the bollard because of the stones which are scattered all over the place. The captain and pilot Marco Simonatti give instructions to find the bollard.
