RAmparts 2500-CL ASD Tug with 70T BP currently under construction and scheduled for delivery Q3 2021.

The hull and skeg of the RAmparts 2500-CL have evolved to provide improved manoeuvring and side stepping capabilities. As with all RAmparts series vessels, the hull has been optimized for maximum thrust and bollard pull, while maintaining excellent manoeuvring 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. Most importantly, 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.
