Vessel Walk Through

Starting aft, the West-Bay 58 features a large fiberglass aft-deck/cockpit. From here, a transom door leads aft and out onto a low maintenance molded in fiberglass swim platform or, one may proceed forward on wide side-decks to the bow. A huge lazarette beneath the aft-deck’s sole provides easy access to the ship’s battery banks as well as to this exceptionally large area for storage and just forward of the lazarette access hatch is the hatch leading forward and down into the walk-in engine room. A set of stairs lead up to the boat-deck over-head or one may enter the salon through dual hinged tempered glass doors.

When opened, the dual doors into the salon from the aft-deck provide abundant bright natural lighting into an already bright and naturally well-lit area. The result of “bringing the outdoors in” has the effect of making the already spacious salon appear even larger and more functional for entertaining guests and enjoying the scenery of an anchorage. The whole of the interior is built of rift-sawn white oak hardwood that has been expertly hand-crafted and finished with stain to a honey tone. This hard wood resists scratching and gouging and after 17 years of use shows why it is a good choice of a quality shipbuilder. The salon features a custom built and most comfortable “U”-shaped sofa on the port side with an oak wood high/low coffee/dining table out front. A pair of swiveling chairs is across the salon to starboard and just forward of these is the entertainment center. Headroom is 6’ 8” throughout most of the interior areas.

The Galley is forward and up 3 carpeted steps from the salon and on the port side and a wide easy stairway leading up to the fly-bridge is across to starboard. Just forward of these stairs is a dinette which seats 4 comfortably for dining. Forward and on the center-line is the lower helm station with Recaro leather helm chair. Side-doors to port and starboard lead out to the side-decks or, from the pilothouse a wide stairway with carpeted steps lead forward and down on starboard side to the accommodations’ deck for the owner and guests.

From the base of the stairs, the Master’s Stateroom is all the way aft with head and stall shower en-suite. A queen-size bed is built in on the center-line with nightstands and reading lamps on either side of the bed’s mirrored headboard. A cedar-lined “walk-in” locker is forward and on the portside of this stateroom and is next to a stacked clothing washing machine and dryer which is housed inside of a locker with oak wood door. The head is on the portside of this stateroom. There is a mirrored vanity/desk with a make-up mirror and lighting, a chest of drawers and two large and deep drawers underneath the foot of the bed for clothing storage. Additional clothing storage is provided by a large hanging locker which is situated aft and on starboard side. Forward of the master’s stateroom a companionway leads past the second guest’s stateroom with single bunk berths on the portside and shared guest’s head with stall shower to starboard and all the way forward the VIP stateroom with queen-size berth on the center-line and a private access door into the guest’s head.

The fly-bridge or “command-bridge” features a helm station on the centerline with dual seats for a helmsperson and a companion. A hinged aluminum radar arch overhead supports the yacht’s antennas and a Bimini Top shades the fly-bridge. A Boat-deck with tender, chocks and davit are all the way aft and from here, a hatch and stairs lead down to the aft-deck.

The Engine-room houses the two 800 horsepower Caterpillar 3406E main engines, 2 – 20 KW auxiliary generators and twin 500 gallon saddle-tanks for fuel. This area is well illuminated with 110 VAC florescent lighting as well as 12 VDC lights in the overhead.

Broker's Remarks

Providing spirited performance, exceptional maneuverability, excellence in design and engineering and built to the highest standards of craftsmanship, the West-Bay SonShip 58’ will provide years of adventure, exploring the islands and harbors off of the “beaten track”. “Siboney” is perfect for a cruising family or comfortable for 2 couples who want to get away for a long weekend but, the yacht is easily managed by only two persons. The yacht’s shallow draft and an exterior requiring relatively little maintenance combine to make the West-Bay SonShip 58 a fun boat to own.
