| Equipped with the latest in marine
instrumentation, this Cruisers Yachts 4450 aft cabin can navigate
safely day or night. Plus, with an upgraded cockpit audio system
the captain can really crank-it! |
| MARINE INSTRUMENTATION |
 |
To the left side of the helm console, we installed
three control/display units. A Raymarine 10-inch color screen
displays radar, sounder and coordinates obtained via the GPS
navigation unit. Single, split or overlaying radar and chart
screens can be selected.
A Raymarine hideaway sounder module processes signals received
via a thru-hull brass transducer and displays vivid, colorful
fishfinder images to the 10-inch screen.
A stand-alone Raymarine navigation unit receives GPS information
from an antenna atop the radar arch. These coordinates can
also be transmitted to a window on the 10-inch screen via
Sea Talk.
An Interphase Twinscope forward scanning sonar provides two
separate and unique horizontal and vertical perspectives under
the waterline. Twin transducers are contained in a single
thru-hull unit. These phase-array transducers constantly search
for hidden hazards by sweeping a 12 degree beam across a 90
degree arc. The display shows live action of what is happening
in front of the boat in very fine resolution. |
 |
 |
 |
Centered on the arch is a 48-inch 4KW open-array radar scanner.
The motor pedestal is elevated on a ‘white’ powder-coated
aluminum tower. A stainless steel extension pole places the
mast light beyond the rotation of the scanner. To the port side
is the GPS antenna. |
| COCKPIT AUDIO SYSTEM |
 |
The Cruisers Yachts 4450 features two Clarion marine source
units, one in the cabin and one on the cockpit. The cabin system
has a CD changer so we shared the changer’s output with
the cockpit receiver allowing both systems to selectively sync
off the same source. This is a great feature for entertaining.
|
 |
We added a digital remote control along the stairs from the
swim deck to the bridge. This makes volume control and source
selection convenient from the slip or when at anchor. |
 |
Under the helm, we installed an Alpine V-12 four-channel amplifier
and a V-12 monoblock sub-amp. The receiver’s fader operates
from the four cockpit coaxials (front) to the two arch enclosures
(rear) while maintaining constant bass level. |
 |
A plastic cover plate completely conceals the amplifier panel
and allows venting over the top. |
 |
Port side arch coaxial on a polymer spacer to clear the outside
wall of the radar arch. |
 |
Cross-firing starboard side arch coaxial. |
 |
A pair of forward-firing coaxials under the aft deck bench. |
 |
 |
| A pair of Boston Acoustics Voyager two-way enclosures
are mounted overhead under the arch. These speakers conveniently
swivel to project out over the swim deck or slip and can also
rotate to project over the bow deck. These speakers truly sound
spectacular! |
 |
We installed a mighty 12-inch subwoofer in a waterproof enclosure
under the help with hopes that it will vibrate loose any pesty
encrustations that attempt to attach themselves to the hull.
The verdict is still out on barnacle-free bass but this subwoofer
conclusively pounds! |
 |
The up-firing subwoofer is mounted to the top of the locker
interior. This way the enclosure doesn't consume valuable
storage space. Plus, this mounting reinforces the way the
woofer acoustically loads.
Two louvered vents allow the bass radiation to envelope the
bridge and aft deck but keeps water out of the compartment
which conceals the subwoofer. |
 |
On the interior of the vents, a fine fiberglass mesh keeps
bugs out.
While we provided a serious cockpit audio upgrade that will
immerse the passengers in sound at any speed, very little
is visible beyond the arch speakers. All materials are marine-grade
and exposed elements are matching marine white. |
| COCKPIT AUDIO PHASE
2 |
 |
A Clarion marine CD receiver at the helm controls the entire
cockpit system and shares sources with the cabin's CD receiver. |
 |
 A
Clarion equalizer is also installed in the helm console. The
EQ provides 3-way zone controls plus a 7-volt line driver to
deliver adequate signal to six pair of inputs divided among
four amplifiers. The EQ is under a watertight cover. |
 |
A hardwired digital display remote control on the transom
confirms selections and operates Sirius radio. |
 |
A Sirius satellite radio antenna is mounted atop the radar
arch. The cockpit source unit is a CeNet controller utilizing
both a Sirius tuner and CD changer. |
 |
Four amplifiers are mounted to a sealed birch panel. The amp
panel is accessible and concealed. |
 |
A polymer cover panel protects the amplifiers from wet items
stored in the locker. Slots are cut at the top and bottom for
an exchange of air. |
 |
 White
3/4-inch thick polymer panels are sculptured to house two MB
Quart marine integrals per side. This also provides the necessary
depth reduction for mounting in the aluminum arch. |
 |
The factory speakers in the cockpit aft bench seat were upgraded
to the oversized MB Quart speakers. |
 |
Boston Acoustics Voyagers are mounted under the arch to project
out over and beyond the transom. |
 |
Dual 1.25 cu. ft. polyurethane enclosures contain upward firing
twelve inch woofers. |
 |
 To
adequately vent the radiation of two 12-inch woofers four downward
louvered vents were used. The interior of the vents feature
fiberglass screens to keep the spiders and wasps out of the
locker. |
| CABIN AUDIO VIDEO |
 |
A 22-inch widescreen LCD offers a larger screen and higher
viewing location versus factory. |
 |
Behind the LCD a cabinet port was installed to neatly pass
all the audio/video cables. The factory CD receiver is also
behind the LCD. |
 |
We installed a Clarion DVD player and satellite TV receiver
in a custom panel within a cabinet under the LCD TV. |
 |
Both a C-bus and CeNet changer was installed in the cedar
closet. |
 |
An infrared target just below the LCD repeats remote control
commands to the concealed DVD player and satellite TV receiver. |
 |
This radio frequency remote control provides seamless operation
of the interior Clarion CD receiver from anywhere in the cabin.
This eliminates the inconvenience of having to get up to change
the volume, sources or stations. |
 |
A second radio frequency remote control switches four
sources (CD changer, Sat TV, DVD and Sirius radio) between
the cockpit receiver, cabin receiver and LCD TV. Any of the
three systems can select independent sources or share sources.
