Cockwells Modern & Classic Boatbuilding is proud to announce the world début of its new and eagerly anticipated Duchy 45 at this year’s Southampton International Boat Show (SIBS26), the UK’s flagship boating and watersports festival that takes place in the maritime city between 18 and 27 September.

Exuding the classic lines and modern luxury that are synonymous with Cockwells’ award-winning Duchy Motor Launches, the Duchy 45 is the most spacious vessel in the range to date, and is designed to deliver elegant cruising and dependable performance.

Incorporating an expansive saloon, large cockpit aft, super king size master cabin with en-suite heads and inventive stowage, this capable cruiser provides abundant space for relaxing and entertaining, and offers a true sense of indoor/outdoor living.

Double bifold doors to the airy saloon create a feeling of openness, whilst large windows present panoramic vistas and fill the space with natural light and warmth. When the doors and additional sunroof are fully open, the vessel connects seamlessly with her surroundings.

Generously proportioned seating, upholstered with waterproof fabric, encircles the opulent, veneered table, whilst an optional electric bimini shades guests from the heat of the midday sun.

A transom walkthrough gate leads to a full beam bathing platform, which can be lowered into the water hydraulically for easy swimming access or lifting out a tender. Sunbathing pads can be added at the bow for an alternative place to relax on board.

A well-equipped galley with four induction hobs, a combination oven, a double sink and a full-size refrigerator and freezer add all the essential amenities for cooking and dining on extended voyages.

Cockwells’ Duchy Motor Launches are sought-after vessels that combine timeless styling, traditional craftsmanship and relaxed handling with the latest build techniques and innovative technology.

Constructed from low maintenance composites and featuring a new, seaworthy semi-displacement hull design from renowned naval architect, Andrew Wolstenholme, the Duchy 45 is as adept at cruising open seas as meandering through coastal waterways, whatever the weather.

Twin Volvo Penta IPS 600 pod drives power the vessel and integrate the engine, driveline and propellers for an efficient and reliable boating experience, whether cruising at 25 knots or attaining her maximum speed of 31 knots.

Full joystick control, virtual anchoring and dynamic positioning achieve precise manoeuvrability, whilst an optional passerelle facilitates simple stern-to mooring. A bow thruster with optional Seakeeper gyrostabiliser supply enhanced stability in open waters or at anchor.

Our new Duchy 45 blends intelligent design and outstanding performance with the superior build quality of the Duchy Motor Launches brand to elevate your on-the-water lifestyle to new heights. We look forward to working with you to customise your Duchy 45 to create a craft that is uniquely yours, in the knowledge that all optional extras have been carefully considered to optimise your maritime experience.

Your chosen layout matches your personal requirements, whether that is a twin cabin arrangement with fully equipped galley down, or a third cabin below with the galley adjoining the social saloon, to allow plenty of comfortable accommodation and personal space for all aboard. Among the many available customisations, you can also incorporate a flybridge on your Duchy 45, featuring an exterior helm and cockpit seating, to create an additional outdoor area for taking in the view. With our wealth of knowledge, reputation for excellence and exemplary customer service honed during our 30 years in the boating business, Cockwells’ friendly team looks forward to welcoming prospective purchasers to Stand M111 at SIBS26 to showcase just how special the Duchy 45 is and discuss your unique specifications.
