Maritime ministries have undergone profound developments in the last generation. Those involved in seafarers’ welfare and ministry need to continue to develop professionally to help their work adapt to changing realities.

The course is designed for new chaplains, ship visitors and volunteers, but should also be useful for those who have experience in maritime ministry, but wish to sharpen their skills.
