The TRAktor-Z 2500SX is a highly efficient twin Z-drive propeller tug in tractor configuration, catering to both harbor ship-handling and towing duties. Its versatile design allows for customizable options based on individual owner requirements. Like the RAmparts 2400 SX, the TRAktor-Z 2500SX has been modified by Robert Allan Ltd. to align with Sanmar Shipyard's standard production range, optimized with operational input from Sanmar's tug operation department, and designated as "SX" for Sanmar Exclusive.
