Canadian naval architecture firm Robert Allan Ltd. and Chinese shipbuilder Cheoy Lee Shipyards have rolled out the RAmparts 2500-CL, an exclusive new tug series being built by Cheoy Lee.

As with all RAmparts series vessels, the hull has been optimized for maximum thrust and bollard pull, while maintaining excellent maneuvering and sea-keeping. A half-raised forecastle deck helps to keep the working deck safe and dry, while a gently rounded deck line in plan to ensure that the tug can safely and easily come alongside and remove itself from an attended ship at speed. The characteristic double chined stern unique to all Robert Allan Ltd. designs ensures that the tug can run astern at high speeds and maintain good control and directional stability.
