The Stylish and Seaworthy Sirena 64

The Sirena 64 combines a seaworthy hull with big-boat amenities in a midsize package.

Sirena 64 has a Jacuzzi smack in the middle of her foredeck. The three-seat tub isn’t an amenity you typically see on a yacht this size (68 feet LOA), but then again, there are a lot of things on board this Turkish-built, Italian-designed vessel you might not expect.

Sirena is a relatively new company, founded in 2006 by Kıraça Holding. The builder introduced the 64 to the United States at Yachts ­Miami Beach earlier this year, displaying her alongside her sistership, the 56, which was making her world debut. Both yachts are constructed at a 1.7-million-square-foot yard in Bursa, Turkey, where 550 craftsmen, including 80 engineers, employ their skills to put together boats that Sirena is betting will make a splash in the domestic market.

At first glance, the Sirena (which means mermaid in Italian) has lines that are, at once, muscular and graceful, like an Olympic swimmer. Her axe bow complements broad shoulders — beam is 19 feet 3 inches — to make the yacht look like she is ready to run in a seaway, which she is, by the way. I manned the Sirena’s helm off Fort Lauderdale last ­Cinco de Mayo, on a day when I wouldn’t have blamed the company rep if he had postponed the test and retired to the nearest cantina for a margarita. A stiff onshore breeze was blowing at around 15 knots, and the Atlantic was churning with 4-footers that frothed at their peaks. In other words, it was prime sea-trial conditions to see how this boat would behave in the slop.

The Sirena 64’s admirable performance is in large part owed to her standard twin 850 hp Caterpillar C12.9 diesel engines, accessible through either a hatch in the cockpit or a doorway leading in from the crew’s quarters. The engine room has a solid 6-foot-6-inch headroom in the middle section, with slightly lower headroom outboard. Plus, access to all systems and regular maintenance points is within easy reach.

In the guest areas, her amidships master stateroom is ­another noteworthy onboard space: It spans full-beam. The en suite stateroom has a king-size berth, and its head has a 6 feet 8 inches of headroom in the shower. Interestingly, that shower has seating that I would describe as “double mezzanine.” There’s a normal bench seat, and then another bench seat above that, much like you’d see in the cockpit of a convertible with double-mezzanine seating. The space looks like it would actually be a perfect convertible steam room — which makes a lot of sense when you consider where the 64 originates. And I wouldn’t be surprised if a customer asked for that modification soon. Our 64 also had a bidet, which, the Europeans assure me, is becoming a trend in the U.S. market.
