Basic Info

Yacht Name: Duet of Cowes
Builder: Hylas
Model: 54
Year: 2005
Location: West Sussex, UK
Asking Price: $564,000
Designer: German Frers
Hull Material: Fiberglass

Lightly used and highly specified example of the German Frers-designed Hylas 54 raised saloon centre cockpit. Rare to the market and one of the youngest examples to be found in Europe (She was originally supplied in Europe and is CE-marked).


Winner of the prestigious Cruising World Magazine ‘Boat of the Year’, the German Frers designed Hylas 54 has proven herself as a hugely successful and desirable blue water cruising yacht both in the US and in Europe. 

This particular example was ordered to a very high custom specification for the European Hylas importer and has been very lightly used since then with low hours on all her systems and the added benefit of a recently fitted comprehensive B&G/Simrad instrument package. With her push-button rig, electric winches, bowthruster, generator, watermaker, air-con and satellite phone, there is very little to add to make DUET OF COWES the perfect world-girdler or simply an extremely comfortable cruising yacht/liveaboard.

Presently available exclusive of VAT but fully CE-marked (an important consideration over and above her US-based counterparts), DUET OF COWES should appeal to buyers from all markets. Please call for more details.

  • Coppercoat applied to underwater sections
  • The hull sides feature a teak rubbing strake with stainless steel capping. This rubbing strake runs the length of the hull sides.
