The 1021 Gross Ton, Portuguese Registered vessel NRP Schultz Xavier seen in this image was built in Portugal in 1972 and is described as a Naval Auxiliary and Tug that can be deployed on Buoy Tender and Pollution Control duties. This image of her was captured when she was berthed in the Port of Funchal Madeira in December 2009. At that date she was already 37 years old. From my Internet searches in January 2022 it would appear that she is still in service at the age of 50.
