The RAscal Class of compact tugs, exclusively developed by Robert Allan Ltd., addresses the challenges of modern, high-performance Z-drive line-handling and smaller ship-handling requirements. The RAscal 1800, a twin Z-drive, diesel-powered tug, offers maximum efficiency in ship-handling duties for seagoing vessels. Carefully developed based on successful tug designs, it ensures excellent sea-keeping, maneuverability, and stability in all modes of operation. The tug features robust, all-welded steel construction with superior scantlings, heavy-duty deck equipment, and all-round fendering, making it well-equipped for demanding ship-handling operations.
