Delphia 11: 250 horsepower for faster, more efficient, and quieter cruising

Delphia is expanding its range dedicated to coastal cruising with a new version of the Delphia 11, equipped with a 250 horsepower Yanmar 4LV250 engine. The new configuration was developed to increase performance, range, and the ability to handle different navigation conditions, while keeping occupant comfort at the center. The new model will be on display at Port Canto during the Cannes Yachting Festival, from September 8 to 13, 2026, for its world debut.

Delphia 11 stems from the experience gained by Delphia on inland waterways, where river currents, tides, and variable conditions require reliable propulsion and good maneuverability. The objective is to extend these features to coastal cruising as well, offering owners greater control in different operating situations.

14 Knots Top Speed with Delphia 11

The heart of the new configuration is the Yanmar 4LV250 engine, capable of delivering a maximum power output of 250 horsepower. Under medium load conditions, the Delphia 11 can reach a top speed of 14 knots, a value that expands the possibilities of use compared to a configuration oriented exclusively toward peaceful cruising on inland waters.

The increased power availability is specifically designed to handle situations where current and sea conditions may require a more prompt response from the propulsion system. The result is a boat conceived to maintain a high level of control even when conditions become more demanding.

One of the most interesting aspects of the new version concerns efficiency at cruising speeds. At 8 knots, indicated as the optimal cruising speed, the Delphia 11 records a fuel consumption of just 9 liters of fuel per hour. With the standard fuel tank, this allows for a claimed range of up to 350 nautical miles. The availability of an optional expanded tank increases the range to over 450 nautical miles.

This is a setup consistent with the model’s philosophy, which aims to enable extended cruising without having to sacrifice comfort or resort to frequent refueling stops.

More Power and Less Noise

The increase in performance is not the only distinguishing element of the new engine. In fact, Delphia highlights a significant reduction in onboard noise levels compared to the previous configuration. The result is a quieter and more relaxing cruising experience, both when navigating inland waterways and when the Delphia 11 is used on the open sea.

The combination of range, efficiency, and quietness is particularly relevant for a boat intended for cruising: the extra power can be exploited when needed, while at more moderate speeds, the model maintains a relaxation-oriented approach.

The new engine also represents a step in Delphia’s commercial and design strategy. The shipyard aims to expand its presence beyond the traditional realm of inland waters, addressing the coastal cruising market with greater determination. Mark Averhoff, Brand Director at Delphia, explained the philosophy behind the new version: “With the new 250 horsepower version, we offer Delphia 11 owners superior performance when needed and a quieter, more efficient cruising experience when they simply want to relax and enjoy the journey.” Added to this feature is the ability to use the model in different contexts: “It is the ideal combination for both coastal and inland waterway navigation.”

The 250 horsepower Delphia 11 thus becomes a versatile model, capable of bridging two boating worlds that require partly different characteristics: inland waterways and coastal cruising.

Delphia 11 Debuts at the Cannes Yachting Festival 2026

As mentioned, the official debut of the new version is scheduled for the Cannes Yachting Festival 2026, set for September 8 to 13. The 250 horsepower Delphia 11 will be on display at Port Canto. The choice of Cannes takes on a special significance precisely in relation to the evolution of the range: the new Delphia 11 is presented as a model capable of expanding its field of use from inland navigation to coastal cruising.

Delphia is headquartered in Olecko, Poland, and is part of Beneteau Group, one of the world’s leading players in recreational boating. Since 2018, the year it joined Beneteau Group, the shipyard has continued to develop its boatbuilding expertise, focusing on models oriented toward comfort and efficiency. The new version of the Delphia 11 fits into this path, with a project that combines increased power, range, and attention to acoustic comfort.

Conclusions

The new Delphia 11 represents a significant evolution of the model and, at the same time, an expansion of the Delphia range’s horizons. The 250 horsepower Yanmar engine allows it to reach 14 knots, while the claimed consumption of 9 liters/hour at 8 knots and a range of up to 350 miles—exceeding 450 miles with the expanded tank—outline a boat designed for long-range cruising.

Completing the picture is the noise reduction, an element that reinforces the model’s commitment to comfort. The debut at the Cannes Yachting Festival 2026 will therefore be an opportunity to closely evaluate a version with which Delphia aims to consolidate its presence in coastal cruising as well.
