Twenty volunteers and a chaplain from Duckdalben International Seamen's Club lead a daily ship visiting service which on average visits between six and 10 ships every day. This is on top of the 150 seamen who visit the club building each day. If medical, legal or other pastoral support is needed a network of professionals is readily available. The club also visits seamen in hospitals or in prison to support them within this hard time.
The club, which is open 365 days a year, also provides communications services, sports facilities, and leisure activities such as musical instruments and karaoke. There is a shop and a money changing facility and for staff will buy specialist items from shops in and around Hamburg.
