Sealine, From Kidderminster's Big Four Builder to a HanseYachts Brand

Fibrasonic Marine to one of Britain's Big Four

Aircraft engineer Tom Murrant founded Sealine's parent company, Fibrasonic Marine, in 1972 with three partners, starting near Bobbington in Staffordshire with a 23-foot sterndrive cruiser called the 23 Continental. The 1973 oil crisis nearly sank the young company, which survived by subcontracting. In 1978 it introduced the C-Line brand and moved to a larger site in Kidderminster, Worcestershire, and in 1979 C-Line became Sealine. Best sellers such as the 30 Fly and 285 Ambassador followed in the 1980s, and in the 1990s Sealine entered the US market and joined Fairline, Sunseeker and Princess as one of Britain's Big Four.

Ownership then changed repeatedly. Murrant and his partners sold to a group led by Gerard Wainwright in 1998 for a reported $45 million, and in 2001 Brunswick Corporation paid a reported $68 million. Brunswick widened the range upward to the T60 of 2004, then sold Sealine in 2011 to Oxford Investment Group. In April 2013 the company went into administration and the Kidderminster yard closed.

The Hanse restart, and where the F43 fits

Aurelius, the parent of HanseYachts, bought the brand, molds and plans in 2013. From 2014 Hanse built adapted Sealines in Germany and appointed British naval architect Bill Dixon to design every new model, beginning with the S330 and C330 and later the C430 coupe of 2017 and the F430 flybridge of 2018.

The Sealine F43 we cover belongs to the earlier British era. It is a 43-foot 5-inch flybridge motor yacht built at Kidderminster during the Brunswick years, listed on Sealine's website from 2002 and still in the October 2005 brochure, with an aft master cabin, an optional third cabin, a lower helm and twin Volvo Penta diesels from the 370 hp D6 to the 480 hp TAMD75. By 2008 the F42 had replaced it. Do not confuse it with the Hanse-built F430, a separate design on Volvo IPS pods.

Buying a British-built Sealine in the US

Brunswick ownership put Sealines into American dealerships, and some boats were delivered with US-specific equipment, but many on the market today were built for Europe with 220-volt systems. There is no factory support for Kidderminster boats, so parts and know-how come from Volvo Penta dealers, independent yards and owner networks. That keeps prices modest: a used F43 typically asks about $140,000 to $260,000, and good boats often sit in Europe priced in euros or pounds.

Condition and paperwork matter more than year on boats that are now two decades old.

• Exact Volvo Penta engine model, service records and oil analysis
• Shore power system, 220-volt wiring or US conversion and isolation
• Gas installation and locker drain on European boats
• Teak decks, saloon windows and sliding door seals
• Aluminum fuel tanks where accessible
• Shower drain pumps, steering and trim tabs
