Layout and Accommodations:

Skyus sleeps 6 in 3 berths. The owner’s queen berth is in the starboard stern. The port hull has a stern queen and a midship double. There are heads and showers in both hulls. There is a large storage area adjacent to the starboard head, and a workshop area in the port hallway. The galley is up, as is the nav area. The spacious saloon features a U shaped settee, with ample storage underneath. The interior is light Ash, and very bright. Wrap around windows allow great visibility and light. See interior photos.



Galley up, with double sink, 3 burner Force 10 stove with oven, pressure water system and hot water heater. There is significant storage, and a large food prep area. Fully equipped with pots, pans, cutlery, etc. An AC/DC/Propane refrigerator completes the equipment.



The cockpit features a double helm seat, with visibility to all 4 corners of the boat. It is well protected by a dodger and bimini, and has 7 huge lazeretts. The dodger windows can zip down in bad weather. A beefy dinghy davit and outboard motor pad are across the stern.


Electronics and Navigation Equipment

Skyus is equipped with Raymarine Wind, Tri Data, AutoPilot, and NavData instruments in the cockpit, and a remote Multi at the nav area. A Standard DSC VHF radio is inside, with a remote RAM mic at the helm. The wheel steering is controlled by a Raymarine ST4000 wheel autopilot. A Garmin GPS (3 on board) is integrated with the computer, autopilot and DSC radio. The stereo is iPod ready, with speakers in the saloon and cockpit. Other electronics include a recording barometer,.a ICOM 710RT SSB, A Pactor III modem and a ARC EPIRB. See equipment list for more.



The boat is wired for AC and DC, and has 2 batteries with a total of 360 amps. 3 solar panels for 175 watts provide the daily power. Additional power is from a 1000w Inverter/Charger, a 30 amp shore cable, or from the 55 amp alternators on each engine. The solar panels provide enough power to meet the boat’s electrical needs in normal weather conditions, including the watermaker.


Sail Plan:

The main sail is fully battened with lazy jacks. The fractional jib is self tending, making tacking the boat a breeze. . Skyus is rigged for a spinnaker, and has a 20’ wide spinnaker traveler. The standing rigging is Dyform, new in 2001. All lines are led aft to 5 Harken 40S winches. The main halyard is two part to ease raising of the sail.



Canvas includes a dodger, bimini, sail cover, and 3 shade/rain tarps. The cockpit is well protected from wind, rain and sun.



Three anchors, each with 250-300 feet of rode. Bow has custom anchor roller that holds two anchors. A bridle system connects the rode to the bows.



Skyus is wired to connect the GPS to both the DSC VHF radio and to the laptop in the nav area. Paper and electronic charts of the Caribbean are on board. A Yeoman paper chart/GPS plotter is onboard. The nav area is large, with storage underneath. A computer/printer area is adjacent.



The ICOM 710 RT is wired to a Pactor III modem and to a laptop, allowing full ham and SSB communication, as well was email on the boat. The Standard DSC VHF has a remote mic at the wheel, so you can communicate without leaving the helm. There is also a waterproof handheld VHF radio.



There are two 35 gallon tanks with isolation valves. Each tank also has a sight gauge, and a gravity drain hose. The Spectra Watermaker is plumbed to the starboard tank, and produces 200 gallons per day. The watermaker was completely upgraded at the factory in 2005.  The freshwater pump is the new variable speed Jabsco model, and thus very quiet. Hot and cold pressurized water is in both heads and the galley.



There are two independent fuel tanks of about 27 gallons each, plus jerry jugs for 30 more gallons (all fuel jugs are stored in lockers, no deck cargo). Each tank has 2 cleanout ports. All fuel entering Skyus has been filtered by a Baja filter and treated with a biocide.



A catamaran can utilize a RV type refrigerator, as it does not heel. The 3 way frige on Skyus can use 12v, 110v, or propane for power. Running on propane, it is totally silent. It can take care of itself for weeks, allowing the owners to leave the boat without having to have someone run a genset or engine to keep the refrigerator alive. Even a single night away from one’s boat is a major headache for conventional refrigerator owners, and the daily 2-3 hour engine run time to bring down their unit is a major inconvenience. 



See the inventory for all the safety gear. With foam core/kevlar construction, Skyus is unsinkable. It provides a stable platform in conditions that would make monohulls challenging, to say the least. The cockpit area is surrounded by a chest high rigid rail, and standard wire safety lines surround the rest of the boat. There are 5 fire extinguishers, and a number of smoke, CO , bilge and propane alarms. A 406 EPIRB and many flares are on board.



Skyus is equipped with 2 Yanmar 18 hp 2GM20F freshwater cooled diesel engines. Both have been rebuilt, and have less than 2000 total hours each. Straight drive shafts are installed, avoiding the sometimes problematic saildrive units found on many cats. 17” Max props, PYI dripless bearings and weed cutters round out the drivetrain. Each engine burns between ¼ and 1/3 gallon of fuel an hour, giving great fuel economy. Often, only one engine is used when motor sailing. The engines show no smoke, use almost no oil, and start instantly. A cruising speed of 7 knots gives best fuel economy. There is good access to both engines, transmissions, bearings and bilges.



A detailed survey was just done in May, 2006. We have had 4 surveys done on Skyus over the years, and frankly, most were pretty bogus. This one took two+ days, and Chris the surveyor looked at everything and went everywhere.  Skyus got an excellent review, with no recomendations. Contact us if you would like it emailed to you (12 pages).



We have produced several 10 minute DVD videos of our various travels on Skyus. Contact us if interested in you are interested. $10 should cover duping and shipping.
