How would you describe the memorial and its ornamentation?
A single light stained glass window depicting St. Martin, to whom the church is dedicated. Below him is a roundel containing a medieval ship, with the central figure of Christ blessing the fishermen disciples, St. Peter, St. John, and St. James, on the shore of the Sea of Galilee. There is a dedicatory inscription at the base. A scroll surrounds them with an inscription inside. Badges of the various formations and armies where Inland Water Transport played a prominent role are spaced throughout the window.
