After unveiling you a preview of it, today we climb on board the De Antonio D50 Open, which we had the pleasure of testing at the Genoa Boat Show thanks to Pedetti Yacht Sales. This is a very modern 15-metre outboard motorboat with extraordinary deck comfort.

De Antonio Yachts – D50 Open

It’s the most popular boat in all the seas of the world. From the USA to the Mediterranean, yachtsmen are in love with the new walkaround generation. These are evolved weekenders that make deck liveability their strong point, aimed at satisfying those looking for a comfortable and protected environment where, however, absolutely nothing is missing to spend the perfect day at sea.

In this category of yachts, 2021 saw the arrival of a new queen: the De Antonio D50 Open from De Antonio Yachts. The new fifteen-metre boat from the Spanish yard has all the ingredients to be considered one of the most complete models in the range, as it can count on the two features most requested by the market today: an extra-large stern platform with a large sundeck above it and outboard engines, which, in addition to the advantages in terms of performance, also make it possible to eliminate the engine room, resulting in larger interiors. These elements make the De Antonio D50 Open an almost unique model in the 50-foot/15-metre segment. We climbed aboard the D50 at the Genoa Boat Show to see how the largest De Antonio ever cruises.

Starting, as usual, from the stern, the boat immediately presents the large platform we mentioned earlier, also available with the hydraulic up & down system. Immediately above this area we find a four-seater sundeck that hides the tender garage and outboard motors underneath, a main feature of the De Antonio models. To access this compartment all you have to do is raise the sundeck and you’ll always have everything within easy reach.

If this section of the boat is in direct contact with the sea, you only have to move a little further on to find a large wraparound U-shaped sofa with a central table and an outdoor galley in front that creates a safe area even for children. Just forward of the galley we find the helm station with four large seats for maximum conviviality even while cruising.

These outdoor areas can be covered by a classic soft-top or by a carbon, steel and glass hard-top, which can be extended both forward and aft.

The version that took part in the autumn boat shows was fitted with a striking jacuzzi in place of the bow sundeck.

Davide Pedetti of Pedetti Yacht Sail, De Antonio’s Italian importer, warns us: “Instead of the bow tub, you have to imagine a big sundeck. That solution is aimed at a very particular type of owner, but it also demonstrates the great inventiveness and technical solutions that the yard can come up with. If you add up the stern area and the bow area, this boat has a livability on deck that’s really surprising”.


De Antonio Yachts D50 Open – Interior

Interior is equally noteworthy. The main feature of this section is its flexibility and the possibility of customizing it to suit requirements. We start with the basic configuration, which consists of a forward master cabin, a head with separate WC complete with shower cubicle and a full-beam U-shaped dinette that can be converted into a double bed by sliding the small table positioned in the centre.

There’s also this second layout with twin cabins instead of a U-shaped galley. This version can be enhanced with a second head. For those who don’t feel safe taking the boat out on their own and want to cruise with the support of a sailor, it is also possible to have a solution with two cabins (master and double), plus a sailor’s cabin with private head. In all, there are around seven interior options available from the yard.

A boat of this type, dedicated to Mediterranean life, must also have suitable propulsion, but above all a hull that allows the engines to express themselves to the full. The Spanish brand has shown a preference for American Mercury Marine outboards, although owners are free to choose the solution that best suits their needs.

This 15-metre yacht can be powered either by Mercury Racing 450Rs or by the brand new Verado V12s with 600 hp each and a maximum of 1800 hp.

De Antonio D50 - Navigazione

The boat we tested was in the quieter version with four Mercury Verado outboards, 300 HP each for a total of 1200 horsepower. This did not prevent us from reaching a top speed of 45 knots with six people and 400 litres of fuel on board. The test conditions were flat sea and less than six knots of wind. Taking advantage of the waves from a few other boats passing through the area, it was possible to appreciate the goodness of the double-step hull design of the new D50 which, despite a beam of almost 4.5 metres and a weight of 11 tonnes, proved to be fast and easily manoeuvrable, as well as fun to handle. The ideal cruising speed for this model, with the engines we tested, can be estimated at around 4000 rpm when the boat is cruising at almost 27 knots with an hourly consumption of around 174 litres per hour.
