Master Boat Builders launched Saturn, the first vessel in the new H500 series of Rapport 3000 escort tugs built for Suderman & Young Towing Company, marking Master Boat’s entry into a new class of high-performance escort tug design. The Saturn (H500) marks the first of four vessels in the H500 series, with H501 through H503 currently under construction.
