Here is some information about Pas de Deux you may find of interest. She is a blue water cruising catamaran, intended for world-wide voyaging.  Dave acquired her in December 2006 after spending many years researching and sailing boats of various manufacturers and designs and considers this to be his "dream boat" (in addition to Donna). We plan to go voyaging in two years after Dave's retirement in February 2009. With practice, just the two of us will be able to manage this vessel. A true pas de deux!
Her first owner christened her Wildlife and sailed her from the Mediterranean Sea across the Atlantic to the Caribbean . He continued on to the Pacific the hard way - around Cape Horn - and reached Australia. During this voyage Wildlife served as a platform for scientific research on sea life. Her complete sailing logs and other interesting information from that venture may still be viewed at www.wildlifesail.org. Wildlife was shipped back to the U.S. on a transport ship in 2005 and placed on the market for sale.
Pedigree:    Catana Catamaran model 471, hull number 44. This means she is a Catana 47 foot catamaran, version 1 model, and she was the 44th vessel of this model catamaran built by Catana. 
Construction:   Designed by Christophe Barreau and built and launched by Catana Catamarans in Canet En Roussillon - France in September 2001. This design is known for its strong but lightweight construction, asymmetrical hulls, high aspect ratio daggerboards, tulip shaped bows, and extremely high bridgedeck clearance - resulting in a fast and safe voyager.
The composite hull materials used in construction include vinylester resin, coring with PVC closed cell foam, unidirectional cloth for the outer laminate and Twaron (similar to Kevlar) aramid cloth for the inner laminate. All 21 structural bulkheads are cored with Nidacore honeycomb core with carbon fiber on both sides. The mast is constructed of carbon fiber rather than aluminum to reduce weight aloft.  
Dual helm stations with mechanical rack and pinion steering provide redundancy and permit an unobstructed view forward and upwind on any point of sail . Pas de Deux features wide and clean, flat topside decks. All sail controls lead aft with no lines or hatches to trip over.
Vital Statistics: Displacement:   approx 25,000 lb. (w/typical loading)
                        Length Overall: 47' 
                        Length Water Line:  45' 3"
                        Beam:  25' 3"
Draft:    4 feet with daggerboards up/8 feet with boards down
Sail Area:   1,615 ft2 (main, 80 m2; genoa, 57 m2; spinnaker, 140 m2)
Mast Height:   70' 6" above water (excluding antennas)
Diesel Fuel capacity:  211 gallons
Fresh Water capacity:  211 gallons
Propulsion:   Two 50 hp MD-22 Volvo diesel engines with Volvo SD120 Saildrive transmissions driving folding props. Each engine burns about 1 gallon per hour at a normal load of 2500 rpm. This results in a boat speed of just over 7 kts in calm conditions with one engine. Just under 10 kts can be achieved with both engines at max throttle. Thus, with 211 gallons of fuel, the motoring range is over 1400 nautical miles.
Sails:   Fully battened main sail, a roller furling 150% genoa, a symmetrical spinnaker, and a storm jib . Under sail, in winds of 20 kts, sustained boat speeds of 12-15 kts are typical. The previous owner reported a top speed of 26 kts surfing down a wave.
Deck Hardware:   Eight Harken winches, including one electric powered main winch. Two winches also serve to raise and lower the daggerboards. The two mainsheet winches are also used to raise and lower the dinghy. An electric windlass is provided for anchor handling.
Electrical Systems:    The Pas de Deux Electric Company keeps things well charged. 12VDC and 110VAC power is provided by batteries and an inverter. The batteries consist of two each 12V dedicated engine starting batteries (230 total amp hours), and eight each 12V gel house batteries (920 total amp hours). In an emergency, the batteries can be cross connected in various ways to ensure at least one engine can be started. The batteries are kept charged by six each 110 watt Siemens solar panels, two 60 amp and two 130 amp alternators driven by the diesel engines. AC power is inverted from DC by a MasterVolt 110V, 60Hz, 2500 watt inverter. This also provides 100 amp battery charging when connected to shore power - which we have been successful in avoiding so far.
Water Systems:   Fresh water capacity is 211 gallons stored in two tanks beneath the floor boards amidship in each hull. Port and starboard fresh water pressurization systems supply hot and cold running water to the galley, head vanities and showers, washing machine, and to the outside port side transom shower. Port and starboard hot water heaters are powered from either AC or engine heat. The port and starboard pressurization systems can be cross connected, providing redundancy.
Seawater is provided to the galley sink by a foot pump for washing dishes. Fresh water is also provided to the galley sink by a separate foot pump to save battery power.
The freshwater can be supplied from the dock or, when at sea, by a 380 gallon/day de-salinator (reverse osmosis water maker) powered by 12V DC. At sea, our fresh water will be purer than at home.
Automatic bilge pumps are located in each main hull and each engine room. Two manual bilge pumps are provided for the main bilges.
Electronics:    The current complement of electronic instrumentation includes B&G instruments for wind speed and direction, boat speed, water temperature, and depth with two remote cockpit repeaters. Navigation electronics includes Furuno 24nm radar, one system integrated GPS, and two backup GPS receivers. We have a sextant as a manual backup.
A Raymarine autopilot with controls at the starboard helm station and navigation station will automatically maintain a course based on compass heading, apparent wind direction, or it will follow a designated GPS route. At the push of a button, the autopilot will even tack the boat to a designated apparent wind angle on the opposite tack, allowing short handed sail handling.
Prior to setting out on long range cruising, we will upgrade much of the electronic navigation to state-of-the-art, including chart plotters, portable remote autopilot controls (to steer the boat from anywhere on board), a new DSC VHF radio, and integrate it all with a computer.
Galley:   Stainless propane 4-burner range and oven/broiler, 110VAC microwave, and small appliances allow us to cook pretty much just like in a real home. A gas grill mounts to a fishing rod holder in the cockpit.
We have two 12V refrigerator/freezers with air & water cooled compressors - a 7 cubic foot top loading version and a 3.5 cubic foot front-loading version. Each can be adjusted to be either a refrigerator or freezer.
Miscellaneous: Lighting fixtures are located throughout the interior. A red night vision light is positioned above the top opening frig for night time chart reading.  Externally, cockpit overhead lighting and foredeck lighting is provided.
The two heads are typical of cruising yachts. Each sanitary system is equipped with a holding tank for temporary waste storage which is required in U.S. waters.  Each head enclosure includes a fresh water shower, although we probably will only use the shower in the starboard head since it's so much bigger and to lessen the cleaning chores on the port side. The best (warm weather) shower is on the port transom steps!
A Splendide 110VAC washer/dryer in located in the starboard hull. The "dryer" function uses a cold water condensation method which we expect to be less effective than clothes pins on the lifelines.
Alas, we have no heat - which is why we'll follow the warm weather once we start cruising. We've used a space heater and electric blanket (connected to shore power) during the winter, allowing us to remain cozy.
In warm weather we install solar shades on the salon windows to lessen sun heat in the interior. All opening ports have mosquito screening and sunshades. The cockpit is shaded by a Sunbrella bimini top. We plan to make our own cockpit side curtains for early and late day shade at anchor.
We have lots of storage space for spare parts, provisions, etc. under the seating and under the berths.
The two aft berths are generously king sized along with a vanity of wardrobe lockers and shelving.
The interior is finished with ash veneer with teak trim.
Our CD/stereo player has speakers in both the salon and cockpit.
Safety:   Water tight bulkheads separate the living areas from the two bow lockers (crash boxes) and the engine rooms meaning hull damage at either end of the hulls will not result in main hull flooding.  Even if totally flooded or capsized, positive flotation will prevent sinking. In the event of capsize, the inboard facing hatches in the starboard head and port forward berth serve as escape hatches.  Nylon webbing is attached on the outside of the hulls near the escape hatches. This serves as an emergency hand hold and safety harness attachment if exiting the escape hatches is necessary.  
Six individual crew safety harnesses and lanyards are available for offshore and/or rough weather use.  A Plastimo offshore 6 person canister liferaft is stowed below the rear crossbar with an emergency pull handle.  A 406 MHz Satellite Emergency Position Indicating Radio Beacon (EPIRB) is aboard and is specifically registered to Pas de Deux. When activated it will transmit a distress signal to satellites to allow determination and reporting of position anywhere in the world to rescue agencies.  We have multiple fire extinguishers and life preservers.
Finally, our dinghy, a Zodiac YL 320 RIB with 9.9 hp outboard serves as an escape pod as well as a "commuter" boat.
Communications:   Pas de Deux is equipped with numerous means to communicate with the outside world.  A fixed mount and handheld VHF radio are the preferred means for ship-to-ship, ship-to-shore, and emergency/distress calls for short distances, up to about 20 miles. One of the antennas on the mast head is for the fixed mount VHF. We plan to upgrade the fixed mount VHF to one with DSC capability that can broadcast and receive GPS coordinates when broadcasting or receiving distress calls. 
For longer, worldwide communications we have a SSB (single side band) high frequency radio. The SSB provides access to both marine and HAM frequencies and we have obtained our HAM operator licenses. The SSB has a Pactor modem that will link to a computer for worldwide e-mail. The tall whip antenna on the stern is for the SSB.
Also for at-sea, world wide communication we have an Inmarsat Mini-M satellite phone for voice (which we will register prior to distance cruising) and an Inmarsat C satellite computer link to send and receive text messages if we wish to register for doing so. The dome and cone shaped antennas mounted behind the solar panels are for these components. We also plan to add equipment designated for wi-fi access.
Our ICS Nav 4 Navtex Weather/Notice To Mariners receiver provides text weather information and navigation notices for our sailing area and understands our location from its link to our GPS, issuing us the information that applies to where we are at any given time off the coastal US. The other antenna on the mast head is for the Navtex.
Finally, we still have our cell phones for US near-shore connections.
Oh, and a Sirius satellite radio keeps us connected to Radio Margaritaville!
