Brief Summary

The 58 Coupé made her North American debut at the 2019 Miami Boat Show and she’s shown no signs of slowing down. Sirena actually had no interest in building a Coupe until its customers, largely in the Northeast, requested it. And this is part and parcel of the Sirena mindset… it listens to its customers and responds accordingly. She’s now the smallest in the lineup and is largely a U.S. boat. She's powered by Volvo Penta with CAT as an option.

Captain's Report

The Sirena Marine 58 Coupé opens up a whole new realm of coastal cruising for a new set of boaters.

By Capt. Steve

Mission

Her low profile has shown immense popularity with the coastal and inshore cruising set that has to contend with low bridges, while not wanting to compromise on build quality or offshore handling capabilities.  And for that, the Sirena 58 Coupé is well qualified. 

Major Features (Including Distinguishing Features)

  • Lower air draft makes for an ideal great loop boat.
  • Single-level deck from the aft cockpit forward to the helm.  No trip hazards.
  • Light and bright salon space, with optional dual sliding sunroof panels for unobscured visibility in all directions.
  • Maintains Category A offshore rating. 
  • Strength of build and flexibility of interior options.

Performance

The Sirena 58 Coupé has an LOA of 61’ (18.58 m), a beam of 17’6” (5.33 m) and a draft of 4’1” (1.24 m).  A recent storm had just passed through the area and prevented us from testing this boat, but Sirena Marine has done extensive testing on the 58 Coupé and they provided us with their test results.  Here’s what they report. 

With an empty weight of 68,480 lbs. (31,062 kg), full fuel, full water and two people on board, they had an estimated test weight of 76,280 lbs. (34,600 kg).  With 2' to 3’ (.61 m to .91 m) seas, she topped out at 24 knots and her best cruise was found to be at 2100 RPM and 17.5 knots.  At that speed, the 41 GPH fuel burn translated into .4 nautical miles per gallon, giving her a range of 365.2 nautical miles. 

Engines/Engine Room

The engine room is accessed from the hatch in the aft deck.  Choose from either the Volvo Penta 670s or Caterpillar 650s for base power.  Options include the Volvo 900-hp or CAT 800-hp.  The boat we were on was powered with the Volvo 670s. 

A hatch in the aft deck allows for engine room access.

Upon entering, my first impression was that the engine room was a lot bigger than it needed to be but that was because this owner didn't stock it with everything that could go in here.  Items such as a second generator, a dive tank compressor, extra air handling system, a fuel polisher, a watermaker, a water filtration system… the list goes on and on, so there's more room than we would normally see in an engine room.  And to be honest, I kind of like it.  There's 5’3” (1.6 m) of overhead clearance and a full 3’10” (1.17 m) between the engines. There’s diamond plating decking all around, including over the Seakeeper 9 gyrostabilizer. There are two fuel tanks, one to each side, so we can either isolate them or connect them with a crossover.   The crossover is probably a better idea because you've also got the 23kW generator that is feeding off of the port tank.  Now an important note with these fuel tanks is that because they are made in-house, customers can easily order another tank to increase the range of the boat.

Sirena created what is among the most spacious engine rooms in class.  It allows for a multitude of optional equipment. 

Both engines are connected to V-drive transmissions. The port engine has an extra alternator that's feeding the demand on the House batteries.  There’s a valve on the starboard engine’s cooling system so when there's hot water going through it, we can use that to heat the hot water in the boat.  That means we don't always have to use the electric hot water heater. 

Boat Inspection

Aft Deck

The aft deck social zone starts with a 7’8” (2.34 m) bench behind a solid wood table on a pair of fixed pedestals. A sunpad is just behind surrounded by a stainless-steel rail.  Just ahead, there's an electric grill with an automatic shut-off for when the hatch is closed.  Underneath is an icemaker.  To the opposite side, there’s a single basin stainless-steel sink and underneath that is a cockpit refrigerator. All of this is under the protection of the extended overhead 7’ (2.13 m) off the deck, and we can further increase the shade by bringing out a retractable SureSHADE awning. I like that there are boarding gates to both sides of this aft deck, so it doesn’t matter which side we have the dock on. 

The aft deck has a sunpad behind a lengthy couch.  A solid wood table is on two pedestals.  Forward is a grill with icemaker to starboard and to port is a sink with a refrigerator. 

In the quarters, heavy-duty rollers are mounted to big stainless-steel chafing gear.  There’s a big bollard just behind and an optional warping winch. The excess line is stored in a compartment just behind and it’s nice to see that the controls for the winch are up high rather than on the deck.  Of course, this is all repeated to the opposite side. 

Heavy-duty line handling gear is to both quarters of the aft deck. 

Platform

The platform is accessed from stairs to port and starboard.  In the transom, there’s a door that leads to what could be crew quarters, but this owner chose to utilize this space for a laundry room.  It includes a Miele washer and dryer right next to each other at the base of the entry steps.  If we make this the crew quarters, there would be a berth in this location.   There’s a wet head over to the port-hand side.   

There are stairs to both sides leading us down to the teak swim platform.  It measures 6’10” (2.08 m) from the transom, 4’7” (1.40 m) of it is submersible.  Notice the door in the transom that leads to the optional crew quarters.  
This owner chose the laundry option, but if the crew option was ordered then a berth would go in this position.  A wet head is to port. 

Bow

As we make our way to the bow, the side decks measure 21” (53.34 cm). This boat has a symmetrical layout, so each side is the same width.  It's so easy for a builder to shortchange one side or the other just to get more space inside, but that's not happening here.   The Sirena 58 Coupé has a 17’6” (5.33 m) beam so it’s easy to keep that 21” (53.34 cm) width to both sides.  There’s also a significant safety factor of 35” (88.9 cm) high bulwarks.   

The bow entertainment zone starts with a forward-facing seat. There’s an option of having a table just ahead of the seat.  Further ahead, there's a triple-wide lounger. The seatbacks lift into chaise lounge position in two separate heights.  There’s also a large storage compartment forward and to the center. There are pop-up LED lights surrounding the lounging areas, adding to the allure after the sun drops below the horizon. 

The bow represents a major social zone rather than an afterthought of “drop a sunpad there and call it a day” type of arrangement we see from a lot of builders. 

Master Access

The hatch next to the couch leads to the master stateroom below. 

To the sides of the forward-facing couch are two hatches.  The one to starboard leads directly to the master stateroom, an interesting feature in and of itself.   The one to port is just storage, however, inside is a ladder that attaches to two points to starboard on the windshield brow, giving us access to the overhead so we can do servicing on the overhead antenna array.  Now because the storage for that ladder is to port, I’d like to see the mounting points for the ladder be to port as well. 

The ground tackle consists of a Lofrans windlass with heavy-duty cleats to the sides.  Notice the beefy rollers in the hawseholes. 

Galley

As we move to the interior, there are two sliding doors that give us an opening of 51” (129.54 cm).  This leads us to the galley, which is located right between the two social zones on the main deck.   The features start over on the starboard side with plenty of Corian counter and open serving space.   There’s a double basin stainless steel sink with covers that have dedicated storage right underneath.   There's a Miele four-burner induction cooktop and above is a vent hood that you just pull out to activate.   Just below is a convection microwave oven.  Directly across are four refrigerated drawers and these can be ordered in any combination of freezers and refrigerators. 

Galley Options Abound

Sirena is well known for providing options and the galley area is a prime example of just how a customer’s muscles can be flexed.  We've seen plans where one will bring the aft counter way out and then add a drop-down window to create a serving area.  Another plan reverses both sides of the galley.   

Salon

Moving into the salon, it's just a step up that reduces the ceiling height to 6’6” (1.98 m), so “reduces” is a very subjective word.   There’s outstanding visibility all the way around through large windows and of course the huge forward windshields.  There are manual blinds, but electric blinds are an available option. Seating starts with a U-shaped settee over on the port-hand side wrapping around an expandable pedestal table.  Directly across is opposing L-shaped seating.  There’s storage underneath the seating, but Sirena doesn’t make you lift the cushions and instead outfits the sofas with drawers.  A cabinet lies just ahead that houses the entertainment system and there is a wide variety of components offered, all connected to the 50” (127.00 cm) flatscreen on an electric lift at the top of the cabinet.   Because this is a coupe version and not the flybridge, we also have skylights that open and we can slide shades across. 

The salon is ahead of the galley and consists of opposing seating surrounded by glass.  Notice the single step up separating the two rooms. 

Helm

The helm is port-side mounted and it starts with two large displays on the upper panel.  Air conditioning and heating vents are on the sides and I like seeing that.  The digital controls are over on the left of the console. There’s a Garmin autopilot and a ZipWake controller.  The compass is right in line with the wheel.  Just behind the compass are the emergency stops and I'd like to see them in a more remote location. The ignitions are also right in front of the wheel. A Volvo Penta display is over on the right side.  Further to the right are all the electrical switches and nestled somewhere among them is the horn.  I’d always like to see that stand out so it’s more easily and quickly accessible.   

The helm is well laid out but we’d relocate the emergency engine stops to a more remote location. 

Now here's one note about the steering wheel on our test boat. It’s mounted to a tilt base and that makes it protrude a bit more from the console and reduce space between the helm and the seat.  I don’t feel the tilt wheel is necessary but it is owner requested.  Standard is a flush mount to a fixed base that takes up much less space, so no points taken for that. 

The helm seat is not so much double-wide but more of a seat and a half wide at 41” (104.14 cm).   There's a manually opening window to the side and that means one less thing to go wrong years down the road. 

Lower Decks

In the standard layout, the master is aft, the guest cabin is to port and the VIP is forward. 
The optional two-cabin layout is ideal for shared ownership as it really offers two master staterooms. 
Here we can see how the companionway takes us to a door to a raised balcony at the head of the master berth. 

Now let’s head below. In the case of our test boat, we had the optional three-cabin layout.  The companionway is to the starboard side of the helm station and it has been given a redesign for this model year.  Previous versions just seemed a little steep and narrow, but that is certainly not the case here. Instead, there’s a distinct comfort level when negotiating these stairs.  They lead us through a door to a balcony overlooking the master stateroom.   There’s a set of stairs immediately to starboard that lead right up to the bow.   From this elevated vantage point, we have a good view of the windows to both sides with opening portlights.  There’s plenty of storage going all the way around the stateroom.  There’s a chest of drawers up forward with shelf space on top.  There’s also a 43” (109.22 cm) TV that's recessed into the forward bulkhead.  The 74” x 60” (187.96 cm x 152.4 cm) island berth is center-mounted on the keel with nightstands to both sides. Overhead clearance is 6’5” (1.98 m). 

The master is entered from a balcony just behind the berth that gives an elevated view of the stateroom. 
The private ensuite has Corian counters, a hullside window with an opening portlight, storage behind mirrored doors, a vessel sink with a modernized faucet and a separate shower stall with rounded doors.  

VIP

The VIP stateroom is to starboard and it has a berth that measures 62” x 75” (157.48 cm x 190.50 cm) up against the starboard bulkhead.  Overhead height is the standard 6’5” (1.98 m) that we’re seeing throughout the yacht.  There's a hullside window with a manually operating shade or electrical is available as an option.  There’s storage just behind, underneath the berth and in a hanging locker with a mirror on a swivel behind the door.  The private ensuite has a walk-in shower, a vessel sink, more Corian counters and an opening portlight.

The VIP is to starboard and the berth is up against the starboard bulkhead. 

Guest Stateroom

Now for the guest stateroom, this one has twin berths and plenty of options are available. We can put a filler cushion in the middle, we can get an option to slide the berths together or have a queen size berth as we saw in the previous stateroom.  This one also has a hullside window and a wet head just in front. 

The guest stateroom features twin berths but there are several options to choose from. 

Options to Consider

  • Cockpit control station.
  • Stern crew quarters.
  • Most work is done in-house to options for material choices, colors and patterns.  Feel free to dial in as the heart desires. 
  • Two or three-cabin layouts. 

Price Range

The Sirena 58 Coupé lists in the area of $1.9 million. 

Observations

This boat has a comfortable layout and not having a flybridge opens up a world of possibilities for cruising.  In its current layout, it doesn't have the desired 19’ (5.79 m) great loop air draft because of the antenna array on top. But if you request a reconfiguring of that to a collapsible version, then this can easily be turned into a great loop boat.  It just makes for another attractive cruising possibility to an already attractive coastal cruising boat.  And “coastal” is a loose interpretation as she has a Category A offshore rating, which covers largely self-sufficient boats designed for extended voyages with winds of over Beaufort Force 8 (40 knots) and significant wave heights above 13’ (3.96 m) but excluding abnormal conditions such as hurricanes.  So, there’s that.
