Who name of the vessel, person

Maritime support (breakdown assistance)

If you require maritime support (breakdown assistance) where there is no immediate danger, contact a (commercial) support provider for help. For example in the event of engine problems, a broken mast, if you need to be towed or something else. The overview below lists a number of organisations that operate in Dutch waters. The Coastguard runs an operational centre for the coordination of emergency assistance in situations where lives or vessels are in immediate danger.
