IMTRA, a manufacturer and importer of quality marine products, announced today its Side-Power SH1000 thruster system has been installed on the fourth hull of the 114-foot U.S. Navy Range Training Support Craft (RTSC-110). Selected to replace another supplier used on the previous three builds, IMTRA worked with Florida-based naval architecture firm DeJong & Lebet and San Diego builder Marine Group Boat Works, LLC to determine ideal size requirements for a system optimized for the RTSC-110.
