For those who love it, it is known, few things are better than cruising. The long days spent at sea, the peace of a roadstead, the hull breaking water moving toward its destination. Pleasant contexts in each case, but ones that “big brands” are increasingly looking to, trying to maximize toward its limit every aspect of the experience. On this front, offering a next-generation cruiser committed precisely to providing the ultimate cruising experience, comes Sirena Yachts, which introduces a new 25-meter in its segment. It is the Sirena 78, the latest design signed by Frers Naval Architecture & Engineering and Cor D. Rover Design Studio for Sirena, an elegant cruising yacht for experiencing the sea to the fullest.

Clean, elegant lines, flybridge available in several variations to suit every need, 4 double cabins, spacious indoor and outdoor lounges, and performance that is no small feat given the size: 23.7 knots top speed. All, designed to best marry on-board comfort with the surrounding sea, offering more than 1,500 nautical miles of range. This is the new Sirena 78, but let’s take a closer look at it.

The lines are clean, bold, with the hull full of minimal details to draw an elegant profile. The two elevated decks are best integrated, with the upper one, the flybridge, available in several options, starting with a fully open one(Open Flybridge), rather than one in which it is surrounded by glass(Semi Enclosed), with an aft deck instead wide open to the water.

Looking at the outdoor spaces, however, it is worth starting right away from the transom, where a large, water-side beach, connected to the cockpit by two stairways on the port and starboard sides, respectively, welcomes you. The furnished cockpit immediately accommodates rises these, an area protected by the upper fly and also usable while sailing. But the real treat of the open spaces, looking at the main deck, is not so much this as the forward lounge. It is here, in fact, that the main open area is located, complete with a large central sundeck facing forward that is contrasted by two L-shaped sofas served as a coffee table.

Complementing the open spaces, however, is the fly, in each of its possible layouts. While the Open Flybridge version instead offers a full raised terrace, protected by hard top, the Semi Enclosed version does not, however, fail to grant open-air spaces, with a remarkable aft terrace, a balcony that, depending on the owner’s needs, can be either furnished or unfurnished.

Siren 78 – Interior

As the cruiser that she is, the Sirena 78 cannot fail to offer interiors that are up to the task, spacious given her size, and above all bright, strong as she is with windows on almost 360° of her perimeter. Starting from the main deck, in fact, as soon as you pass the cockpit, you are introduced to an elegant and well-kept environment, complete with an initial furnished living area and followed by a large convivial area with a dining table and full kitchen. Just beyond it finds a place for the dashboard.

On the flybridge, however, the second wheelhouse takes its place, as does a second interior lounge area, complete with a piano bar served by stools. All this, surrounded by large windows in the case of the Semi Enclosed version, and then facing the open air aft, with the terrace mentioned earlier.

Shifting the focus to the sleeping area does not change the music, with the interiors still well maintained and tastefully furnished. The center of the boat houses the main cabin, a large full-beam double complete with large en-suite bathroom, dressing room/cabin closet, work area and sofa, in one version, but alternatively available with two en-suite toilets, at the expense of the sofa, which leaves room for a larger closet to compensate for the absence of the dressing room/cabin closet.

Proceeding toward the bow, however, are two separate twin bedded cabins, both complete with private bathrooms. But the second large cabin actually waits even further forward, in turn strong with a large double bed, full furnishings and en-suite toilet.

Accessible from the stern, totally independent, is then the crew area, here available in different configurations, both in terms of the amount of beds and their arrangement (2/3), and in terms of the distribution of services and furnishings.

Sirena 78 – Motorization and performance

Coming to the more technical front, the new Sirena 78 will be powered, in its standard engine version, by a pair of MAN V12 engines of 1400 horsepower each. Optionally, however, the shipyard also makes available two additional options designed to increase propulsive power. In this eventuality, a choice would then become available between, respectively, a pair of MAN V12s with 1550 horsepower each, rather than a second pair of V12s, also MAN, but with 1800 horsepower each.

In terms of range, bolstered by a 9,000-liter fuel tank, the Sirena 78 offers about 1550 nautical miles at an economical cruising speed of 10 knots. The actual cruising speed, on the other hand, is around 16 knots, while the maximum speed is 23.7 knots.
