She is a beautiful, unusual cruising catamaran, admired wherever she goes. She is a comfortable, simple and safe boat and home. Such spacious cosy accommodation is rarely found in multihulls.
Sailing her is easy and a lot of fun, with the excellent performance of her modern aero junk rig.
She is a seaworthy boat having sailed 40,000 miles from England to New Zealand via the South Atlantic, Indian Ocean and Tasmania.
I've built and lived aboard several over the last 40 years, and sailed 1000's of sea miles. Oryx is the culmination of that experience.
If you are wanting a beautiful, unique and affordable boat to fulfill your dreams - look no further.

Hull Material
Decks Material
Engine Volvo Penta 2002,18HP, 2 cylinders, fresh water cooled with a Volvo 120S saildrive. 3 bladed feathering 'Kiwi' prop. Engine hours not known. The engine was bought second hand with reputedly less than 1000 hours use. Since installation in 2012 the engine has been used less than 100 (one hundred) hours a year. The engine is rarely used but regularly maintained and started so it runs reliably when needed. The engine being in the starboard hull means that Oryx turns easily to port (ahead and astern), but turns less easily to starboard. In normal use this presents no problems but maneuvering in a marina in windy conditions is difficult. 70Amp alternator charges dedicated engine starting battery (but not house battery). 25lt plastic fuel tank in cockpit locker providing gravity feed to the engine plus 25lt reserve in jerry cans. Consumption is approximately 1.5lt per hour cruising at 4knts. Exhaust temperature alarm fitted.

Ground Tackle
Two bow rollers on a forward beam Two large aluminium mooring bitts at the forward end of a bridge deck. South Pacific VS1000 electric vertical anchor winch with rope chain gipsy and warping drum. Up / Down control switch on a lead long enough to be used anywhere on the deck and cockpit.

Batteries - 2 Trojan 6V golf cart batteries (giving 200 Amph at 12 V). Batteries charged by 2 solar panels (on the caddy roof). Solar panels give 120 Watts (180 Watts + 40 Watts). Digital solar charge regulator gives display of a battery management info. 150 watt inverter giving 220 volts. Navigation lights - Tricolour plus all round white light (on starboard mast head). LED 3 NM range. Steaming light (on starboard mast head) incandescent 10 Watts. Port, Starboard and Stern light - LED at deck level. Anchor light fixed LED on cuddy roof. LED Lighting down below.
Electronics / Navigation
VHF - Radio Ocean RO4800, DSC + AIS. The VHF radio receives the AIS information with a small display screen (with various AIS alarms). It is connected to the chart plotter which also displays AIS information. Chart Plotter - Lowrance Elite-5M HD. Navionics chart (East coast of Africa, South East Asia, Australia, New Zealand, Pacific Islands). NASA Clipper GPS cockpit repeater (gives boat speed + GPS information). Raymarine ST40 depth sounder. Cockpit Compass - Plastimo Contest bulkhead mounted (viewed inside the cabin too).
Sail Inventory
The rig is Aero Junk. Sail cloth - 6.5oz tan polyester made in 2012 in good condition. There are 5 wishbone battens. Fore and aft sails set in between. Wishbone battens are Meranti reinforced with unidirectional glass fibre. The yard is a spruce wishbone. The sail is sheeted to each batten / wishbone.
Mast / Rigging
Hollow clear Douglas fir sheathed with glass and epoxy with two pack polyurethane paint. The masts are in tabernacles with self draining troughs set into the deck. This allows the mast to be hinged down for maintenance or access under bridges. Starboard mast has cable running up it for tricolour and steaming light.
Three part halyard. The aero junk is a modern variation of a split junk rig but handling and reefing is as easy as a more traditional junk rig. The sail is controlled by a halyard sheet and two down-haul lines. The fore and aft part of each sail set with an aero dynamic shape on each tack. The forward part of the sail creates a slot effect to the aft part. This gives more efficiency to windward and when reaching than the traditional junk sail (see the photos).
Deck Gear
The sails sheet to either side of the cockpit. All controls for raising and lower the sails are grouped together on a top of a starboard side of the cuddy. There is one single speed, self tailing, number 20 winch to assist in raising the sails but rarely needed.
Oryx is a cruising catamaran with no pretensions to high speeds. While double digits speeds are often experienced when running and surfing I would usually reef when the speed gets much above 8 knots. Sailing to windward Oryx will tack through 100 degrees and will sail at 6 to 7 knots if the sea is not too rough. While there is some interference with the sails with the wind abeam this is largely overcome by easing out the windward sail and sheeting in the leeward sail, but reaching is a fast point of sail anyway. Running downwind is pure pleasure and the steering steady even with the self-steering and a burst of surfing over 10 knots. Oryx is very easy to sail with all control lines led into the cockpit with no need to go on deck to raise or reef the sails. Oryx can easily be sailed single handed. The cuddy at the front of the cockpit give great shelter from wind, rain and the sun.

The engine is rarely used because Oryx is so handy to sail, tacking up quite narrow channels can be done effortlessly and sailing on and off the anchor is almost always done. Oryx is great fun to sail.

Oryx is based on Bernd Kohler KD860 design - link - which I modified to suit my needs. I chose a Bernd Kohler design because he specialises in plywood construction and his building method is simple and elegant. The basic structure remains as designed and has proved to be very strong. The hulls are dory shaped, built from 9mm marine plywood with the bottom being 2 layers of 9mm. The full width of the deck above salon, library and galley is made of two layers of 6mm marine plywood because of an extra camber. The remaining deck area is 9mm marine plywood. The boat is built on 9mm plywood bulkheads with spruce stingers. The 3 main structural bulkheads that join the hulls are also 9mm plywood, reinforced with 400 gm biaxial glass fibre. The glue and coating epoxy is West System and the whole of the exterior is sheathed in 200 gm glass and epoxy.
The main changes to the design were to lengthen the boat to 10 meters to give much improved accommodation. This enabled the fitting of a much bigger and comfortable saloon as well as providing an exceptionally good galley. The extra length also gave room for a separate full length single berth at the aft end of the port hull, as well as good size heads to fit the diesel sail drive, this also gave a lovely roomy cockpit. The original reverse sheer deck line was altered to a much more attractive "Newick" type sheer. The topsides have a step in the hull which gives much useful extra space inside the hulls, particularly in the galley as well as visually more pleasing lines.
The most obvious change is to the rig. The Aero Junk gives all the main advantages of the junk rig but also gives the sails a good aerodynamic shape which greatly improves performance to windward and when reaching.
Originally the design had 'anti vortex' panels at the inside of each hull to provided leeway resistance. While these worked well at speeds above 5knots, they were not efficient at lower speeds and after 12 months they were removed and replaced with fixed low aspect ratio fin keels. This increased the draught from the original 2 foot (0.6m) to a still reasonable, 3 foot (0.9m). The new keels work well at all boat speeds.
The original rudders were lifting 'dagger-boards' type which had two faults. The mMost significant was that they appeared to be too small and tacking was not completely reliable. The other problem was that they would 'kick-up' when surfing at speeds above 10 knots
Since the addition of the fixed keels no longer required lifting rudders they were changed to fixed balanced rudders with 20% extra area. Tacking is now reliable and steering much improved, particularly with the wind vane steering.

I had built three yachts before Oryx (Stormalong, Badger, China Moon). They have been built for myself and to the highest standards. Oryx was built to my best ability with the priorities of strength, longevity and ease of maintenance. The philosophy of Oryx was to build a simple boat that was easy to maintain completely by myself. Several so called luxuries such as pressure water and refrigeration were avoided so that time could be spent enjoying sailing and the places visited rather than waiting in harbour for hard to get spare parts and tradesman to repair them.
