Mission Statement

Sirena designs the 88 to be an expedition yacht with offshore capabilities. Noted naval architect German Frers drew a hull intended to run smoothly and efficiently. She highly customizable with a full-width beam master stateroom that has its own fold-out balcony and four more cabins to accommodate up to a dozen people. Dining options range from formal to al fresca and the stern is available in a variety of configurations.

• Fold-out balcony from the master stateroom
• Full-beam master stateroom on main deck
• Customizable stern layouts
• Huge flybridge area
• Joystick combines controls and thrusters
• Helm station in cockpit

Features Inspection

The Platform. The Sirena 88’s stern is fully customizable. For this owner, a door in the transom raises hydraulically to reveal a 13½’ (4.11m) wide outdoor gathering area. Additionally, the center section of the platform hydraulically extends and lowers into the water and there’s a passerelle for boarding from a sea wall in the starboard steps. Options being requesting include removing the garage door altogether to keep the area wide open and adding a crane for launching water toys or a tender. These options are possible because the boat’s transom is actually farther forward and the stern is installed as a separate piece. One owner made the beach club, but had the coffee tables customized with notices that convert them to a table for holding a tender.

Cockpit. Stairs on each side of the swim platform lead into the Sirena 88’s cockpit, which is the first of many entertainment venues on the boat. Each passageway closes with an acrylic gate framed in stainless steel. A u-shaped settee wraps around an 8’8” (2.64m) x 3’1’” (.94m) solid teak table with lacquered wood and stainless-steel inlay work. Deck chairs can be added to seat 10. Overhead protection is provided by the extended flybridge and there’s 6’10” (2.08m) of headroom. Forward, just abaft the salon entry door is a cockpit control station with a joystick, shift/throttle and side-thruster controls.

Side Decks. From the cockpit, it’s an easy step up to the side decks that are protected overhead and symmetrical at 2’ (.61 m) side. The port-side passage stops at the amidships area, providing access to the formal dining area and galley. To starboard, the passageway leads to the on-deck master stateroom. Bulwarks come up to 21” (53.34 cm) and the rails mounted on the caprails top out at 34” (86.36 cm). As we worked our way forward, we saw the largest sliding glass door—9’ (2.74 m) wide—we’ve seen to date. More on this later. Just across are a boarding gate and we’d like to see a grabrail in this area.

The Bow In the center of the Sirena 88’s foredeck is a 10’ x 7’4” (3.05 m x 2.23 m) sun pad that has space for at least three people. There are cupholders and grabails on each side and the headrests can be raised to create chaise-style lounges. As we continue forward, there’s a 4’5” x 7’2” (1.35 m x 2.29 m) pool with a glass front and pop-up lighting in the forward corners. To both sides are padded seats and teak steps to facilitate pool entry. Grounding tackle consists of twin stainless anchors and in the deck are two hatches flanking a windlass plus a forward hatch that opens a forward rode locker with a built-in ladder.

Bridge Deck

The Flying Bridge. From the bow, looking aft to starboard, we see the entry to the master stateroom. More on this later. The stairs to port lead to the flying bridge and there is a small balcony just ahead. In a word, the Sirena 88’s flying bridge is huge with 7’ (2.13 m) of headroom under the hardtop and inside that top is an electrically powered sunroof that measures 8’ (2.44 m) wide by 9’ (2.74 m) long. The flying bridge table is 8’10” by 3’1” (2.69m x .94m), it has the same detailing as its countertop in the cockpit and there’s seating for 10 around it. To port, the bar has a granite countertop with a lower lacquered level that has a large prep area, a sink, refrigerator, an icemaker, and a grill. Aft to port is a hot tub and there’s open space to starboard. It can be left open or covered with a Bimini top that has carbon-fiber stanchions at the trailing edge while the forward edge secures to the back of the hardtop. Underfoot, all decking is teak. Forward to starboard, the flying bridge helm has two seats that slide fore and aft. In the electronics panel, there are twin 18” (45.72 cm) Simrad screens and on the lower section, the auto pilot is to port with the compass in line with the leather-wrapped steering wheel. To starboard are twin MAN engine displays, the thruster controls, the joystick that combines the thrusters with the transmissions and the digital engine controls. Below at knee level are the Simrad VHF alongside the engine start-stop switches.

The Pilothouse. Stairs adjacent to the flying bridge helm lead down to the Sirena 88’s pilothouse. Because the manufacturer still had some work to do on this area after the show, any measurements we took would not apply to how the final product will look. We’ll describe the area, but won’t be providing specifications. Highlights in this area include three 24” Simrad screens, the engine management displays, the autopilot, and all the digital controls found at the other stations. To starboard are a chart table, a power distribution panel and stairs that lead to the salon. To port are off-station sleeping quarters with a berth that measured 82” long by 45” wide (208.28 cm x 114.3 cm).

Main Deck

The Salon. Moving down the stairs and to the main deck, it should be noted that all the Sirena 88’s decks are design to be floating to provide vibration and noise reduction. Inside, the manufacturer combined elegance with functional styling. Decking is hardwood, the overhead is 7’ (2.13m) off the deck and there’s recessed lighting in the valances. Windows run from the overhead down well below the backs of the lounges, letting in ample natural light. The seating starts with a sofa and two freestanding chairs around a lacquered coffee table to port. To starboard is another sofa. Attractive cabinetry work is done by Sirena’s in-house craftsmen and an artfully finished woodwork separates the salon from the formal dining area. Storage to starboard includes a wine chiller at the bottom. The dining area seats eight and the forward bulkhead has plenty of built-in storage. Doors to the side decks are on each side with a 4-footer (1.22 m) to port that leads to the galley and the mammoth 9’ (2.74 m) glass door to starboard that lets in a surplus of natural light.

The Galley. Our test boat had the European-style smaller galley designed for crewmembers to prepare the food and bring it to guests. A larger one is also available. It’s equipped with everything needed to prepare full meals, including a pair of sinks forward, a Miele four-burner stove and oven, a dishwasher and full-sized refrigerator.

The Master Stateroom. A companionway leads from the galley past the pilothouse and a day head to the full-beam master stateroom. The doors are all solid-cored and have stitched leather panels separated by mirrored strips. There are hullside sole to overhead windows on each side that can be swapped out for balconies. Each window has fitted electric blinds. To starboard is a sitting area and the center-mounted berth measures 78” (198.12 cm) x 81” (205.74 cm). There’s 6’9” (2.06 m) of standing headroom and 4’9” (1.98 m) of space over the berth. The headboard is upholstered in padding with mirrored details. Perimeter lighting is under the berth. To port, there is a desk with storage alongside. Built-in cabinetry is ahead of the berth with storage underneath and to starboard is a 48” (121.92 cm) TV. Just ahead, are two sliding, mirrored doors that lead to the master head.

Master Head. Directly ahead of the sliding doors are his and her sinks with contemporary fixtures under a full-length mirror. Light comes from the overhead curved skylights. Just to port is the shower and our test model had a tub, but it was ordered by the owner. Usually a steamer shower would be in this position. To the opposite side are stairs leading to the bow. It moves electrically and, to ensure privacy, the switches are only on the inside. To starboard of the steps is the toilet for the master head.

Below Decks

Aft VIP Stateroom At the bottom of the stairs that lead belowdecks, there’s an elevated platform in the companionway that runs fore and aft. We’ll start with the aft stateroom, which is on par with master staterooms we’ve seen on most yachts. These quarters carry most of the same features as the Sirena 88’s master. The berth is mounted on the centerline and measures 69” (175.26 cm) x 79” (200.66 cm). Headroom is 6’7” (2.01m). At the forward bulkhead is a 55” (139.70 cm) TV and to port is storage behind a glass paned door. Alongside this is a desk/vanity with a mirrored top, all inboard of a large hullside window with an integrated portlight. On each side of the berth are three-drawer nightstands and next to the entry is another glass door that opens the hanging locker. In the head to starboard, there’s a sliding mirror above the rectangular sink and in front of the hullside window. The shower closes with a glass door.

The 55” (139.7 cm) bulkhead-mounted TV in the aft cabin is another luxury touch.

Pantry/Laundry. As we depart the aft cabin, just to starboard is a walk-in pantry with storage, open counter space and a small under-shelf refrigerator. Farther forward to starboard is a laundry room with stacked Miele washer and dryer, more open counter space and a hullside window.

Twin Guest Staterooms. Working our way forward, there are two guest cabins to port and starboard with individual berths that are 2’ (.61 m) apart. Each cabin has 6’7” (2.00 m)  of headroom and the berths measure 78” (198.12 cm) x 32” (81.28 cm). There are storage drawers in the berth base, plus hanging lockers and hullside windows with opening ports. Mirrors are on the back of the entry doors and doors for the en suite heads, both of which have walk-in showers with rainfall heads and hand-held wands.

VIP Bow Cabin. Continuing to the Sirena 88’s bow, there’s another VIP cabin that is separated from the passageway by a door just ahead of the guest staterooms. Pass through the door and there’s a walk-in closet to port, then a split-head arrangement with the toilet to port and the full-sized show stall to starboard. Moving in to the quarters, it’s three steps up and because of the boat’s plumb bow, there’s no crammed-in feeling around the berth. The stateroom has 7’2” (2.19 m) of headroom and the berth measures 79” (200.66 cm) by 68” (172.72 cm). Hullside windows to port and starboard have opening ports. Below the bulkheads are trimmed in stitched leather with stainless and wood trim. More satin-finished teak trim is at the entry, there are opaque windows and seats at the foot of the berth. There are also storage drawers in the base of the berth.

Crew Quarters. The crew accommodations are accessed from the port side deck and space on the Sirena 88 is designed according to European standards. For the U.S version, the access will change, as will the amount of dedicated crew space, including the addition of a small galley area. This one consists of over-under berths to port, a work desk and the wet head. The larger captain’s area is to starboard.

The Engine Room. A watertight door separates the crew quarters from the engine room, which is extra-large. There’s plenty of space for the twin MAN 1,550-hp V12 diesel inboards and the area has 6’7” (2.01m) of headroom and 5’4” (1.62m) between the engines. Fuel-water separators are mounted just behind the engines and to starboard are the hydraulics for the thrusters, windlass and swim platform. Air chillers are just above and notice the vibration-dampening mounts on all components. There are 28kW generators on each side and the main electrical panels flank the entryway. To port, the water manifolds are easily accessed but should be labeled. A ladder leads to a secondary access hatch in the aft deck.

Performance

The Numbers. The Sirena 88 has an LOA of 88’ (26.81 m), a beam of 23’2 (7.10 m) and a draft of 6’1” (1.84 m) and the 1050 x 1020 5-bladed props spin in tunnels in the hull. With an empty weight of 185,188 pounds (84,000 kg), 81 percent fuel, 35 percent water and five people on board, we estimated our test weight at 202,203 pounds (91,718 kg).

With twin 1551-hp MAN V12 engines spun up to 2300 rpm, the Sirena 88 topped out at 23.2 knots. Reducing power at that point increases speed linearly so there is no best cruise setting. We’ve found, however, that diesel engines like a load and 80 percent is optimal. That puts us at an average of 16 knots, which our test boat’s captain tells us is the target speed. At that speed, we recorded rpm ratings between 1825 and 1874 depending on conditions. That produces an average of 91.1 gph for fuel burn and a range of 461.7 nautical miles. For distance cruising, drop down to 1250 rpm where the range is extended to 1,044.6 nm and at 1000 rpm, the boat can run at 9.3 knots for up to 1,617.7 nm with 10 percent of the boat’s fuel capacity kept in reserve.

Observations

Because the Sirenna 88 is fully customizable, no two will be identical. The adaptable stern adds to the one-of-a-kind feel and buyers should expect to spend a good deal of time going over features to make the boat their own.

Beyond the versatility, many thoughtful touches went into this custom yacht from the hull to the forward pool and aft Jacuzzi. Whether an owner wants to stay close to home and entertain a crowd on the huge flybridge or invite 10 friends on an extended cruise, the Sirena 88 is designed and equipped to accommodate both groups effectively.
