Marketing Description “Fidget” is a beautifully presented and exceptionally well-maintained example of the highly regarded Sealine F37 Flybridge. Powered by the larger and more desirable twin Volvo Penta KAMD300 engines (285hp each) with approx 590 hours. Lovingly cared for by her current second owner for an impressive 18 years, she has been fastidiously maintained throughout her ownership and presents a fantastic opportunity for anyone looking for a well-equipped, low-hours cruising motor yacht. With just 590 hours on her engines and a comprehensive service history, “Fidget” has clearly benefited from a level of care rarely found on a yacht of this age. Most recently, a major service was completed in October 2025, together with the replacement of the stern gear, including P-brackets and shafts, representing an investment of over £18,000. She is exceptionally well equipped for comfortable cruising and extended stays aboard, including Eberspacher D4 diesel heating, bow and stern thrusters, electric windlass, davits, a full navigation suite, and a complete set of cockpit covers, including a flybridge cover.The Sealine F37 is renowned for combining excellent accommodation with impressive cruising capability, and “Fidget” is a particularly appealing example. Her long-term ownership, low engine hours, extensive maintenance history and recent significant investment make her a yacht that deserves serious consideration.“Fidget” really does need to be viewed to be fully appreciated.
