Vessel Overview

Designed by Arthur Defever, at nearly 84' overall, NSS PATTAM is a gorgeous cruising home and will always be a head turner in any harbor.

As a cruising trawler, she is totally self-sufficient: a large fuel capacity, to go for those far horizons, a very efficient galley for ease and comfort in the preparation of meals while underway.
