Cloud 9 is a well-equipped example of the popular Sealine F37 flybridge motor cruiser. Powered by twin Volvo Penta KAMD300 285hp diesels on shaft drives, she has approximately 365 hours recorded and is fitted with both bow and stern thrusters. Her specification includes Raymarine Axiom 9" and 12" chartplotters, Quantum radar, Eberspacher heating and a Seago liferaft new in 2025. The engines were comprehensively serviced in June 2026. Her current owners purchased Cloud 9 in April 2024 and have cruised locally around the Harwich and Felixstowe area. They are now selling due to lack of time to use her. The owners also advise that Cloud 9 was the F37 taken by Sealine to the boat show in 2003.
