The new Hylas M47 introduces a distinctive approach to recreational power yachting in the United States by pairing a contemporary 47-foot hull with diesel outboard propulsion. As one of the first models of its kind to reach the American market, the M47 combines long-range capability, fuel-efficient diesel engines and a thoughtful interior layout designed for comfortable cruising and extended passages.
Performance and Range
The M47 is equipped with twin Cox CXO300 diesel outboards, which deliver a top speed of 31 knots and a comfortable cruising speed of 17 knots. With the standard four-blade propellers, the yacht achieves an impressive range of roughly 1,000 miles. Owners who require even greater endurance can opt for a larger fuel tank that increases the theoretical range to as much as 1,500 miles, making the M47 well suited to extended coastal cruising and passages where fuel availability is a consideration.
Diesel Outboards: Efficiency, Reliability and Service Life
Diesel outboard propulsion is a defining feature of this model. Diesel outboards are often promoted for their fuel efficiency and robust durability, and the Cox engines fitted to the M47 come with tangible manufacturer support: a 5-year, 1,500-hour warranty, and an expected engine life rating of up to 6,000 hours. Those specifications underscore the emphasis on long-term reliability and lower operating costs over time, particularly for owners who plan frequent or long-distance use.
Interior Layout and Onboard Comfort
The M47’s interior is arranged to balance liveability with efficient use of space. The salon contains a generous L-shaped settee and a teak table that can be converted into an additional berth, providing flexible sleeping and social arrangements. Forward, the master cabin features a queen-sized berth, offering a dedicated owner’s accommodation with privacy. Amidships there is a guest cabin to accommodate visitors, and the vessel includes a single head serving the accommodations.
Galley and Practical Details
The galley is equipped to support extended cruising. It includes two pull-out refrigerator units and a top-loading freezer for ample cold storage, alongside a four-burner propane range with oven and broiler for full meal preparation. A practical aft galley window opens and can be secured, allowing fresh air and a connection to the cockpit while underway—an appealing detail for cooks who enjoy ventilation and views during passage-making.
Intended Owners and Seamanship Considerations
The M47 is especially attractive to recreational mariners who value range and durability. It is also likely to appeal to sailors transitioning from sailboats to power yachts: the familiarity of diesel propulsion can make the shift in systems and maintenance easier for owners who already have experience with diesel engines. The combination of an efficient diesel powerplant, substantial fuel capacity and a comfortable interior creates a platform for owners focused on cruising capability rather than short, high-speed runs.
Design Highlights
While the M47’s most notable technical distinction is its diesel outboard setup, the overall design reflects Hylas’s intent to offer a modern cruising yacht with practical features for liveaboard comfort and extended trips. The arrangement of refrigeration, cooking facilities and convertible salon seating demonstrates attention to the everyday needs of cruising couples or small families, while the fuel capacity and engine rating support longer offshore legs.
