This Sport Yacht has some unique amenities. Like a rotating mirrored disco ball with full multi-color lights. Or, a trio of horns that are louder than a freight train. There’s cool video and audio too.

   
DISCO BALL

Suspended from the center of the cockpit a mirrored disco ball rotates reflecting an array of multi-color LEDs.

   

When not in use the disco ball easily detaches leaving the DC motor. The motor and all lights are mounted to a common white acrylic panel making this a fully reversable procedure.

   

 

An array of different colored LED fixtures surround the ball. As the ball rotates so rotates the multi-color pattern throughout the cockpit. Plus, this system has the disco bass to match.

   
MASTER BLASTER

Three pneumatic horns tuned at different frequencies are incredibly loud. We installed a pump and tank in the engine compartment with air lines running up to the hardtop.

A KVH TracVision is elevated with our custom aluminum tower featuring a kidney-shaped base to perfectly fit the rear of 420 and 44 Sundancer hardtops. KVH brings the hip hop countdown or ESPN anywhere on the water.

   

A polymer access plate was added underneath to facilitate the KVH mounting.

We also installed a dockside antenna and ship-to-shore switching for DirecTV service while under the boathouse.

We installed a 20-inch LCD TV on the port side arch. The picture is viewable from every seat in the cockpit.

   

The LCD is well behind the depth of the sink console below.

   

A quick-release bracket allows EZ removal and reinstallation. The power cable and coax run through to an aluminum mount. We have multiple brackets, ie: straight, horizontal angles, vertical angles and compound angles. This particular model is a compound angle to compensate for the inward arch lean and to rotate the LCD screen slightly toward the rear of the cockpit.

   
COCKPIT AUDIO

Factory CD receiver and changer in salon AC/DC service panel.

   

Concealed within an overhead salon cabinet we fabricated a white laminated enclosure to house a number of new components. An equalizer and two line-level controllers combine for a 5-way zone control, ie: cockpit, external, sub, bow and transom speakers. A source selector switch, DC receptacle and minijack provide full iPod support. We also added a ship KVH to shore dish antenna switch.

Upgraded arch speakers.

   

We added a third pair of cockpit speakers to the rear cockpit. This addition is essential for balanced output throughout the cockpit. Factory doesn’t provide rear speakers on the 420 and 44 dancers. A custom polymer kit recesses the rear starboard speaker into the combing so that the deck clears as it is motorized to gain access to the engine compartment.

   

A downfiring 10-inch subwoofer was installed in the console that wraps around the captain’s chair and supports the helm bench seat. The space is shared by the cockpit air conditioning unit. A custom slotted white polymer vent allows the bass radiation to flow freely from within the console.

   

Three louvered grills in the rear cockpit bench console provide enough surface area to vent the output of two downfiring 10-inch subwoofers.

The three Boston Acoustics G2 10-inch woofers are impressive. And, the bass is seamless anywhere on the cockpit.

   

Bow rail speakers project back towards the bow deck pads. MB Quart marine coaxils are loaded into white powdercoated spun aluminum bullet-shaped pods. Polymer adapters and polymer clamshell brackets mount the pods to the bow rails. Watertight stainless steel two-conductor connectors make the hull penetration. White cable is used for the exposed run.

   

Another set of MB Quart speakers in white pods project out over the transom. White polymer adapters are contoured to the hardtop interior arc and also correct for the downward angle.
   
When in the party mode, one pair of speakers per bow and transom was not enough for this captain. So, we doubled up on the bow rail speakers and amplification.
   

Plus, we added four WetSounds pods from under the hardtop to project out over the swim platform. And, we upgraded power to a large Boston Acoustics two-channel amp to drive the WetSounds.

From bow to cockpit to transom, this boat is L.O.U.D. everywhere!
LIGHTING

White polymer bezels conceal LED fixtures used to illuminate the first step out on the gunwale walk. Red diodes are used on the port, while green diodes light the starboard side.

Here is another version of a full Sea Ray 420 Sundancer system.

Sharp Aquos high–def 20-inch widescreen LCD TV with digital tuner receives local digital broadcasts. Digital modulation also allows cockpit viewing of satellite TV and DVD.
   
Concealed satellite TV receiver is controlled via a radio frequency remote control allowing operation from anywhere in or on the boat.
SALON SURROUND SOUND
Within a salon overhead cabinet we installed the relocated CD changer. We also added three salon audio controls on a common panel. A volume control serves to blend in the forward center channel speaker. A second pre-level controller provides adjustment for the salon subwoofers. A remote turn on/off switch allows the salon system to be defeated while leaving the stateroom speakers operational.
   
A Boston Acoustics 6 1/2-inch coaxil serves as the front overhead center channel speaker. The factory grill was replaced with a cloth that is more acoustically transparent

Dual louvered vents under couch allows bass radiation to flow from twin concealed 8-inch subwoofers.
STATEROOM AUDIO
A pair of Boston Acoustics coaxils replaced the factory. We also replaced the factory grill cloth.
   
A concealed volume control provides local control and also allows the stateroom speakers to be turned off.
COCKPIT AUDIO
Within the AC DC service panel we moved the CD changer out to an alternate location and replaced it with an exterior audio control panel. Placing the zone controls next to the source unit conveniently collects all controls. We also added a radio frequency remote control to the factory Clarion CD source unit and added an iPod station at the helm.
   

A three-way rocker switch toggles between three sources; satellite TV, iPod and salon TV output. The switch controls a hide-away electronic switcher that delivers the various sources to the CD source unit’s auxiliary input.

An equalizer functions as a six times 7-volt line amp that drives ten channels of amplification producing the required dynamic headroom. The EQ also provides a triple zone control; cockpit, subwoofer and external to cockpit. Two additional controls book ending the EQ split the external zone into separate bow deck and swim deck areas.

   

Six MB Quart marine coaxils are evenly distributed throughout the cockpit. Multiple high-pass amplifier channels allow us to gain the system for even and seamless output. We added new locations at the cockpit rear. The starboard AFT speaker is recessed with a custom polymer trim ring and adapter plate for a totally flush installation to clear the motorized engine hatch.
