The RAscal Class of compact tugs have been developed exclusively by Robert Allan Ltd., to address the challenges of modern, high-performance Z-drive line-handling and smaller ship-handling tugs. The RAscal hull form has been carefully developed, based on a wide array of previous successful tug designs, to ensure good sea-keeping, manoeuvrability, and stability in all modes of operation.
The RAscal 1500 design is a high performance, twin Z-drive, diesel-powered line-handling tug, designed for maximum efficiency in the performance of line-handling, ship-handling and related terminal support activities. The vessel is equipped with heavy bow fendering for ship-assist work. An aft staple and tow-hook are fitted aft for line-handling and general towing duties.
The hull, deckhouse, and wheelhouse are of all-welded steel construction with scantlings in excess of the minimums of any Classification Society. The vessel is equipped with heavy duty deck equipment and all-round fendering for all ship-handling operations.
