Sailing enthusiasts will easily remember the Argentinian architect German Frers, Swan's regular designer, whose drawings gave birth to many racing boats that excelled in famous races: Admiral’s Cup, Whitbread, Giraglia... Yet, the designer has never turned his back on motoryachting. He proves it with this model he penned for Sirena, a well-established Turkish shipyard that enjoys an 150 000 m2 industrial facility in Istanbul. Born in 2006 to manufacture Azuree sailboats, this shipyard has finally entered the motoryacht sector with the brand Sirena. Its goal is ambitious: to build a range of units from 50 to 120 feet, starting with this 58 that looks like a navetta - an Italian trawler, if you like. A glance at her distinctive exterior design shows an overwhelming emphasis on verticality that gives the Sirena a serious nature. The transom, bow, main windscreen and flybridge wind deflector are also straight. And so are the rectangular portholes.
A performance worthy of the genre
We discovered the Sirena at the last Cannes Yachting Festival. She was moored in front of the port exit, ready to cast off. Her propulsion is classic: twin 650 hp Caterpillar diesel engines, each coupled to a shaft line transmission. She also features a joystick (engine reversal and bow thruster) for delicate manoeuvres. Inspired by the beautiful weather, we took the helm on the flybridge, where are located a helm station with a two-seater bench and a massive dashboard offering a complete range of navigation and control instruments. Under the thrust of the two 8.7-litre 6-cylinders, the Sirena established a performance curve of up to 2 160 rpm, below the top speed of 2 300 rpm announced by the engine manufacturer. Perhaps, her propellers were not ideal... Thus, the top speed we recorded was 21.8 knots and the recommended cruising speed: 15.8 knots at 1 750 rpm for a 384 miles range. The noise level figures are within the standard. At this same pace: 76 dBA in the lounge and 68 dBA in the VIP cabin.
Two or three cabins
In terms of outdoor facilities, hats off to the fly of nearly 30 m2. A beautiful space where the shipyard easily fitted a helm station, a solarium built up against a salon for four to six guests, two equipment (kitchenette and refrigerator) and three deckchairs. In the standard layout, the foredeck offers a relaxation area with a lounge and a sunbed. As an option, the latter can be replaced by a small pool. The Sirena also features a cockpit entirely sheltered by the flybridge structure, whose traditional layout features a sofa, a table and four seats, in other words an al fresco area for six. The Sirena's interiors were also entrusted to a famous signature: Tommaso Spadolini, who successfully combined in a unique space an aft galley, a lounge/dining area facing a three-seater sofa and the wheelhouse, with its single portside seat. However, circulation on board requires discipline since space is limited. Thanks to half-way up windows, natural lighting makes this place pleasant to live in. In its standard version, the lower deck accommodates three cabins. The full-beam master is located amidships and enjoys its own bathroom with an independent shower. It also features a king size bed, iust like the forward VIP. Between these two cabins is located an en suite twin. Note that if four berths are enough, the shipyard also proposes a lower deck with two masters. In both versions, the Sirena offers a skipper cabin, accessible via the transom on the bathing platform.
Starting from the principle that a navetta is, a priori, not intended to sail at over 20 knots, the Sirena meets this specification, and many others, including her three cabins and beautiful outdoors .
