Maritime Propulsion: Expanding Options for Waterjets
It’s no surprise that waterjets are great for shallow-draft, highly maneuverable craft, but vessel designers are busting out of the old stereotypes.Vessel designer Aircat Vessels has developed a surface effect ship (SES) crew transport catamaran, AIRCAT 35 Crewliner, that can sail at over 50 knots and manage offshore transfers in 2.5-meter seas. The air cushion system from ESNA dynamically adjusts to sea conditions so the vessel can reduce transit times, reduce fuel consumption…
