The union for maritime professionals at sea and ashore.

Nautilus International is the first truly trans-boundary trade union for maritime professionals, reflecting the global nature of the industry and representing members in the UK, Netherlands, Switzerland and around the world. Nautilus members work at sea and ashore.

Sometimes we are referred to as the ‘Merchant Navy union’, but this doesn’t tell the whole story. Members include shipmasters, officers, cadets, ratings, yacht crew, VTS officers, harbourmasters, river boatmen, nautical college lecturers, maritime lawyers and even ship-based medical personnel.
