The CSO aims to bring the Good News of God's Love to each person involved in a maritime life.

We have evangelists in each of the large harbours in South Africa. They visit the seafaring men on the vessels daily to care for their spiritual needs. Fellow-believers of almost every language and cultural group are our faithful, loyal supporters, donors and co-workers. The CSO has international ties with other organisations and is a member of the International Christian Maritime Association - an umbrella organisation for harbour evangelisation organisations.
