As the King of Siam was prone to say in “The King and I,” “It
is a puzzlement to me.”
I experienced that kind of puzzlement as I
stepped aboard the new Silverton 392 Motor
Yacht, because I couldn’t figure out how the
builder had fit so much space into what is essentially a 37 by 14 foot hull. This boat has two
full staterooms, both of which have heads with stall showers; a large twolevel saloon with separate dining and entertainment areas; and a comfortable galley.
I suppose it has something to do with computer-aided design, which
allows designers to search out empty spaces and fill them effectively, as
well as enabling them to “stack” the boat’s various living areas to get the
maximum space from each level.
Whatever the reason, all you and I really need to know is that this
is one spacious boat for its size. Heck, there are a lot of 50-footers built
a few years ago that don’t have this much room.
The starting point for the Silverton design team was the company’s
successful 37 foot hull — upon which more than 1,200 boats have been
built and sold. Silverton modified the hull for increased stability, to
carry the added weight aloft in this new motoryacht configuration.
The resulting new 392 Motor Yacht offers ample beam, 17 degree
transom deadrise and hard chines, and is surprisingly stable — at rest
and even in a cross sea.
We tested the brand-new 392 off Miami, on an overcast day in sloppy seas. I ran the 392 out into the Gulf Stream, where it shouldered
aside the lumpy swells and showed off 28-plus mph performance.
The boat’s side exhausts and good insulation qualities resulted in a
low 83 decibel sound reading at 4,000 rpm. In fact, this boat was so
quiet that normal conversation levels could be maintained while communicating on both the bridge and aft deck.
At full throttle and at cruising speeds, there was no slamming of flat
panels in head seas. The deck stayed dry throughout our sea trial.
In the engine room, access was excellent to all areas. The compartment has Pirelli non-slip flooring and is well-lit. The generator and
twin air conditioning systems are mounted under the galley/dinette area,
in a separate compartment. It isolates sound and vibration so well that
when the generator was started, I thought it was the refrigerator kicking
This is a very quiet boat, both with the generator alone and with
the main engines.
This family cruiser, measuring 40 feet,
six inches stern to stern, manages to
be both stylish and user-friendly.
Construction is excellent throughout the 392. All wiring is neatly loomed and labeled, there is good access to the ball-valve seacocks
and the hull is solid maintenance-free fiberglass. Lockers are all fully
lined, and even the bilge is gelcoated, for a tidy and easily maintained
All windows are tempered safety glass, engine alarms and a fire
extinguisher system are provided as standard equipment and the “base
boat” is complete — right down to dock lines and life jackets.
Our test boat had a Simpson-Lawrence anchor windlass feeding
from the bow roller into a large anchor locker — and the recessed sunpad on the foredeck seems ideal for relaxing sunny afternoons.
The flybridge helm area is comfortable, with an adjustable seat provided for the skipper and a bench seat next to it that has space for up to
three companions. The bridge’s roomy layout allows guests to move
around freely, without disturbing the skipper.
Teleflex Sea Star steering and a tilt wheel were provided at the
helm, along with Teleflex twin-lever controls. A full array of Faria
gauges are centered in the large dash panel, which still has plenty of
room for adding electronics on each side.
A clear panel in the hardtop gives the skipper full visibility of both
aft corners for backing down. And with the forward bench seat at a
lower level, there is excellent visibility forward, even with a crowd of
Cavernous storage is available under the bridge’s forward “eyebrow”
— which has enough room to store a rolled-up inflatable, life jackets or
deck gear.
Continuing with the 392’s theme of “unexpected spaciousness,” our
test boat had an extended transom platform that was wide enough to
carry personal watercraft or a dinghy. It also featured a huge bin to store
deck gear and power cords, as well as a hot and cold shower.
Guests can board the 392 with ease, thanks to gates on each side of
the transom and transom steps that lead to the aft deck. A wet bar is
provided here, for convenient entertaining, as part of the boat’s standard
equipment package.
Fully molded weatherboards at the aft deck not only provide privacy, but make a full enclosure both secure and weathertight. The fiberglass hardtop is fully finished on the underside, with built-in lighting,
and it is sturdy enough to carry a dinghy and a davit.

Silverton developed its latest
cruiser to answer a number of questions posed by existing aft-cabin
designs. For example, how do you
quickly and safely get to the foredeck from the flying bridge? How do you design helm seating so that any
one person can get up and go below without disturbing the others? How
do you configure a raised aft-deck entertainment area so that the helmsman can actually see the end of the swim platform when backing into a
slip? How do you facilitate boarding from a fixed pier or a floating dock?
And finally, how do you maximize interior living space while providing
two generous staterooms and keeping the boat affordable? Silverton’s
answer to all these questions is its new 392 Motoryacht.
At first glance, the 392’s amalgamation of an aft-cabin motoryacht
(aft) and a flying-bridge cruiser (forward) strikes you as uncommon, if not
downright odd. But here, as throughout the boat, form is determined by
function, making the 392 exceptionally utilitarian. The more you use this
boat, the more apparent that becomes.
A case in point is the flying bridge. To Prevent overcrowding while
giving everyone a front-row view, the bridge is a split-level affair, which
creates a unique “theater” environment. The higher aft row—the “mezzanine”—has a long benchseat divided by arm rests and separate cushions,
forming a double seat to port, a single helm seat behind the centerline
wheel, and a navigator’s seat to starboard. The helm itself is actually a center console, with easy-to-read Faria black-on-white gauges in the center
and “wing” instrument panels to either side. The wings are angled in
towards the helmsman for better viewing of electronics.
Our test boat was equipped with five Raytheon units, and there was no
crowding, either on the dash panel or inside the console. Controls and
switches here are within easy reach.
Forward and lower—the “orchestra”—is another
benchseat for three or four. This area is well protected from wind and spray by a tinted glass windscreen,
and the bench flips up to reveal a convenient wet
locker with drain. Copious stowage—presumably for
canvas, PFDs, and safety gear—is available inside the
foremost portion of the bridge, and six drink holders
are scattered around the area. Thanks to this centerconsole design anyone can head aft from here without
disturbing the helmsman.
The bridge is also the termination of two other
traffic lanes: both side decks which lead to the bow.
To reach them you take five steps down a molded
stairway on either side, and though they’re narrow
(10-inch-wide), they’re protected their entire length
by 10-inch-high bulwarks. A foredeck sunpad is standard, and a stainless steel, hip-level (26-inch-high)
railing extends from bridge to bow. While this
arrangement may seem unconventional, it offers a fast
and safe route to the integral anchor pulpit from
either side of the bridge. And as a bonus, this configuration allows the living spaces of the saloon below to
run full-beam.
From the foredeck you walk up and over the
bridge area to reach the aft deck. Here you must supply your own outdoor furniture, but otherwise the area
is ready for entertaining. A built-in wetbar houses a
U-Line icemaker, cold-water sink, cutting board, and
two-shelf cabinet (bottle racks are needed), and from
here you can also access a huge stowage locker under
the upper bridge seats. I especially like the 110-volt
outlet here (can you say margarita?), along with the
switches that control all courtesy lighting around the
boat and the lights in the hardtop overhead.
Like the bridge, the aft deck has three entry
points—up a molded staircase from the swim platform
or through Delron® doors on either side, which provide direct access from a fixed finger pier. For easier
boarding all three areas have a step recessed into the
deck, and Silverton has added a flip-down panel to
the transom door to cover the instep. All three
entrances have sturdy handrails.

When it’s time to move activities
inside, you’ll find one of the most spacious saloon/galley layouts available
in this size range. The whole area is
bright, since natural light streams in
from three sides. It’s also full-beam
and open; there are no bulkheads to
impede traffic flow as you move from
the companionway steps, through the
saloon, down into the galley, and
then down again to the forward
cabin. It’s almost too open, since
there is nothing to hold onto from
one end to the other—a centerline
overhead grabrail would solve this.
The saloon is very comfortable
and features a teak-veneer-trimmed
entertainment center across from an
Ultrasuede L-shaped lounge that doubles as a sleeper sofa for two.
Silverton craftsmen also came up
with a neat trick here: The underside
of the lid for the small cocktail table
is padded; flip it over and it becomes
an extra dinette seat. I liked the location of the electrical panel—it’s just
inside the companionway and hidden
by a door—and it’s hinged so there’s
nothing to unscrew if you have to get
to the wiring behind it.
The dining area to port and gal-
ley to starboard are down an almost
one-foot step from the saloon, which
may be a problem for those who don’t
notice it. (The drop is necessary to
provide enough height for the
engines, which are directly below the
saloon sole.) The galley is a U-shaped
arrangement and features 7’2”
headroom, a Corian countertop,
dual-voltage refrigerator, threeburner stove-oven, faux-wood
vinyl floor, and plenty of stowage
for pots, pans, and the like (one
cabinet has a built-in Lazy Susan).
Clearly, the 392 was designed for
more than just weekend cooking.
Which brings us to her accommodations. The 392 offers two
private double cabins at either
end, both with en suite facilities
shower stalls—no
small feat for a
Both the guest
stateroom forward
and the owner’s stateroom aft feature two
hanging lockers (one
full length), and the
double berth aft is an
island for complete
walkaround access. If
you’re looking for an aft-cabin cruiser,
you’ll be impressed by the 392’s
All of these features and roominess don’t come without a tradeoff,
which is speed. At wide-open throttle, the 392 registered about 27 mph,
and acceleration from her twin
Crusader 454 XLis was smooth but
leisurely throughout the range. As
you can see from our test results, she’s
quiet, and her hull—Silverton has
used the same design on more than
1,000 37 and 40 Convertibles—is dry
at any angle to the sea. Stability in a
beam sea is good considering her high
freeboard, and she tracks rail-straight
even in a moderate following sea.
The 392’s galley has Corian™
counter tops and full size appliances.
Furthermore, the 392 exhibits surprising cornering
skills. While visibility immediately forward of the bow is
slightly impaired by the height of the center console, visibility aft—thanks to a window in the hardtop and the
placement of the transom door—lets you back the boat into
a slip with confidence since you can see the end of the swim
The 392 may look unconventional, but that’s with
good reason. To get so much room and so many features into a boat this size, Silverton had to get up and
over traditional design thinking, and its utilitarian
approach brings a fresh, new alternative to the traditional aft-cabin cruisers.

Silverton’s new 392
is surprisingly
roomy, inside
and out!
ment is what makes the engine room so hospitable, as that space is
free to hold just the engines.
About all I would change is to attach the ladder with quickrelease pins (like the engine room ladder) rather than with screws,
which would make getting to the water heater easier.
Many American production boatbuilders emphasize style, but
styling can go beyond what’s merely trendy to incorporate some very
practical considerations. According to Silverton’s project managers,
cruising families want safety first, then comfort. A centrally located
helm for visibility and good foredeck access for handling lines and
anchors rates high, and comfortable interior living space is close
behind. I found that the Silverton 392 Motoryacht has addressed
those priorities in a user-friendly package.
It is easy to get to the big-block gas engines for routine maintenance. Just pop open the centerline hatch in the salon to inspect oil
and coolant levels. For major maintenance or engine change-out,
remove the furniture and the large hatches directly above each
Angle-iron mounting brackets support the engines on vibrationisolating couplings, which are through-bolted to the hull
stringers/engine beds. The mild steel was already rusting on our test
boat; gusseted aluminum or stainless would prevent a perennial corrosion problem.
High-quality aircraft-type fuel lines feed the engines through
neatly routed fuel supply and return manifolds affixed to the forward
bulkhead. There were no external fuel filter/separators on our test
boat; they’re available as an option and I consider them essential.
There’s merit in putting the battery switches in the engine room,
since you have to open the hatch and look inside to turn them on,
but I’d prefer they were relocated to improve access to them and to
the fuel manifolds below.
The engine seacocks (there are no internal water strainers) are
outboard of the dripless sterntubes, so they’re hard to get to in a hurry.
They should be inboard of the engine beds aft. Where access is easier. Silverton takes the unusual extra step of providing plugs for the
PVC insert liberhols so you can control liquid flow into the keel area.
Cableways were neatly routed, secured and loomed for protection against chafe except on the starboard side of the aft bulkhead,
where the looming was missing.
The boat’s wide beam helps; even with the outboard 5052-grade
aluminum fuel tanks, there’s plenty of room to change the spark plugs
on the big gas engines. There’s some room in the engine compartment for improvement, but this is a very mechanic-friendly space
with some impressive features and attention to detail, which means
the equipment will tend to give reliable service and enjoy a long life.
Forward of the engine room in a separate compartment are an
optional enclosed Kohler 6.5 kw generator along with the batteries,
poly-water tank, hot-water heater and battery charger. This arrange-
The Silverton is conventionally constructed with a solid fiberglass bottom and Coremat in the sides for stiffness. The bottom
stringer gridwork of fiberglass-encapsulated plywood is laid up in one
piece in a steel jig. It is then inverted and fiberglassed to the hull
(which is still in its mold) to ensure that the whole hull structure
keeps its shape and serves as a true foundation for the interior and
The decks and superstructure are cored with either balsa or
Divinycell foam. Plywood rings surround hatches and stanchions to
reduce the possibility of water penetrating the core and to better
resist the compression loads of mounting bolts. The hull-to-deck
joint consists of outward-turned deck and hull flanges sealed in butyl
tape and fastened with self-tapping screws. The hard PVC rub rail is
then screwed in from beneath. Finally, the whole affair is fiberglassed
on the inside.
Silverton uses computer-aided design extensively. Computeraided manufacturing is used to make the plywood sections for the
tooling used to build the molds and for making interior cabinetry
The Silverton 392 is both avant garde and pragmatic, a nice
blend of form and function. The optional diesels are worth the initial cost for improved
range of speed; you’ll
recoup a lot of the
expense when you sell
the boat and will pay
a lot less at the fuel
If you like the
boat’s looks, you’ll
love what Silverton
does for the roomy
wide-body salon and
all-around topside
safety and accessibility. The company has
a winner in this cruising design and with a
few detail improvements,
could have what
many would consider
an ideal American
coastal family cruiser.
Three new boats have been introduced by Silverton in a corporate
reincarnation driven by an inspired policy of employee ownership, and
fresh designs and technology. The 322, 352, and 392 are the first three
boats in the Side Walk Series, named for unique layouts which feature
cabins carried out to the gunwales, with access from transom to foredeck
on fiberglass steps up and over the flying bridge.
Before the SideWalk Series was even a gleam in the designer’s eye,
Silverton carried out a survey to find out what current buyers really want.
To no-one’s surprise, it revealed that most people use their boats only for
weekends and one longer holiday each year, and want a sexy appearance,
quality construction, comfortable living areas and good speed. As a
result, this boat and its smaller sisters, which target active, medium-sized
families, have unusually spacious accommodations.
DESIGN - The 392 boasts far more accommodation than is normally fitted into a 37’ x 14’ hull: two large double staterooms, each with
heads and stall showers, an immense saloon and lots of storage. Designers
carried the cabin sides, including the bridge, out to the gunwales, leaving
no side decks. There is quick and easy access from the huge swim grid aft
to the anchor windlass forward, via the aft deck and fiberglass steps on
each side of the superstructure. The boat’s appearance takes a little getting used to, but the first step into the saloon reveals a living area normally seen on boats 10’ longer, so the high-sided look can be forgiven.
The new Silvertons are also good sea boats with a respectable turn
of speed. The hull is in the contemporary style, fine forward with 14”
reverse chines and a relatively flat run aft to 17o of deadrise at the transom. Although based on the successful Silverton 37’ hull used on more
than 1,200 boats, this hull has been modified and broadened for extra
weight-carrying capacity and increased stability. It remains almost flat in
fast turns and is stable in beam seas.
The 392 resembles an aft-cabin yacht aft, and a flying bridge cruiser
forward. There’s a large deck above the aft cabin and just below the
bridge, with seating for six or eight and a wet bar with ice-maker, sink and
The flying bridge has the only helm station on the boat, a familiar
feature of Silvertons in the past, although the company now offers a lower
helm as an option. While British Columbia cruisers tend to prefer a fullyprotected lower helm for obvious climatic reasons.
A policy of supplying high-quality minis and side canvas, along with
heating vents on the bridge to cut chill and dampness. The bridge is on
two levels, with the after bench seating and helm station a step higher
than the forward seat, giving driver and guests a clear view.
Standard power on the 392 is twin 320hp Crusader 454 XLI fuelinjected V-8 gas engines, but the boats brought into Vancouver, like our
test boat, will have twin 3116 Caterpillar diesels, developing 350hp each.
A 8kw Kohler genset is standard. The inline-six Cats will produce a top
speed of 26kts and cruise quietly all day at 20kts. The exhausts exit on
each side of the hull, and the engine room is well insulated. The generator and air-conditioning system are mounted in a separate area forward
of the engines, and the only sound they transmit to the living area is a
subdued purr.
A generous equipment list includes an optional Simpson Lawrence
electric anchor winch and a large anchor locker. Aft of the winch a sunpad with mattress is molded into the foredeck. The helm station has
Teleflex Sea Star hydraulic steering and a tilt wheel, with Teleflex twinlever controls. Standard gauges are Faria, and the wide instrument panel
has lots of room for electronics. The swim grid on our test boat was a deep
version designed to carry heavy dinghies or personal watercraft and is
ACCOMMODATIONS - The aft entrance to the boat is over the
swim grid, up five steps to the after deck, then down five steps to the twolevel saloon, with one step down to the galley and dinette. The L-shaped
galley to starboard is large and well-furnished with Corian countertops, a
three-burner electric stove and oven, Norcold fridge/freezer and an abundance of storage. The guest double stateroom is forward of the saloon,
with two hanging lockers and lots of storage under the island berth. The
master stateroom is under the after deck and is even larger. Both staterooms have full heads with optional VacuFlush toilets and stall showers.
The dinette and the lounge in the saloon both convert to doubles as well.
UNDER WAY - The 392 tends to run bow-high at top speed, but
at cruising numbers the bow comes down and the full waterline is used.
The fine forward sections produce a pleasantly squishy ride in a sea, and
the boat is quiet enough to enable normal conversation on the aft deck
and the bridge.
Even with a number of people in the seat forward of the helm, the
driver can see the anchor bowsprit easily for docking and watching for
debris. Looking aft from the helm through a clear panel in the cover over
the aft deck, the helmsman can see the outer edge of the wide swim grid,
giving him all-round visibility for docking.
The 392 has a flying bridge with a molded hardtop over an aft deck
lounge. The two staterooms have custom venetian blinds, cedar-lined
lockers, cherry cabinetry, and TV and phone hookups.
CONSTRUCTION, EQUIPMENT - Construction is solid
hand-laid fiberglass throughout with coring from the waterline to the
gunnels. Cabinets are lined and the bilge is gelcoated for easy maintenance. To save manufacturing costs and in line with Henry Ford’s muchquoted adage, “You can have any color as long as it’s black,” there are no
color options on the outside—white-on-white is standard—and only two
interior color options.
