KACHINA is a high performance 40' cruising trimaran of the Skyhook series by Chris White Designs.
While not a race boat she can compete very well in most PHRF multihull races while sporting comfortable cruising accommodations. She has cruised the US coast and Bahamas and is ready to do that again.
Kachina has demountable crossbeams and can be trasported over the road. She is too large to be called trailerable but can be moved overland if the need arises.
Hulls and decks are epoxy/glass sandwich construction with western red cedar core, and skins of uni-directional E-glass. Crossbeams are epoxy laminated douglas fir veneer, marine plywood and glass fiber, with glass covered foam fairings. Highly loaded areas of hull, beam structures, and deck are locally reinforced with carbon fiber. Each float with its crossbeams, is demountable for transport or storage. Daggerboard and rudder are foam/glass with carbon fiber reinforcement. WEST system brand epoxy resin is used throughout and all structural and finish materials are of high quality. Metal fittings are fabricated of 304 or 316 stainless steel or of 5086 Marine grade aluminum plate.
Mast and rig:
The boat is rigged as a fractional sloop, with double spreaders for fixed diamond stays and capshrouds to the floats. The mast is deck stepped and electrically grounded to the water. Painted Sparcraft aluminum spars and substantial stainless wire standing rigging with Norseman terminals are utilized. Harken battcars and blocks simplify sailhandling and reefing. A topping lift and lazy jacks (both fully adjustable from the cockpit) are rigged. Three reefs are available in the mainsail. There is a two part main halyard and draft is easily adjusted in the loose footed main by means of an outhaul on roller track. As noted above, jib furling/reefing equipment is top quality and works well. Jib lead cars are adjustable from the cockpit. The asymmetrical spinnaker is carried on a 6 foot articulating carbon bowsprit, which is easily swung aside for more convenient mooring or anchoring,
This rig provides ample options for power with ease of control under all points of sail, Boatspeeds of 22 knots have been attained without effort and it is common to cruise very comfortably at speeds in the low to mid teens.
Main: 450 sq. ft. square top, Dacron sailcloth (Maine Sailing Partners 2012), full length battens with Harken ballbearing Battcars, lazy jacks, topping lift, and custom Sunbrella cover.
Jib: 338 sq. ft. tri radial cut ProRadial Dacron (Vermont Sailing Partners 2020) on Profurl NC42 furler
Asymmetrical Spinnaker 950 sq. ft. biradial 1.5 oz nylon (Maine Sailing Partners 2015), flown from articulating carbon bowsprit.
Old Screacher and Harken #1900 furler also available.
Deck Hardware and Layout,
(2) Harken #42 self tailing primary winches, (4) Harken #40 self tailing winches with appropriate Lewmar stoppers for all lines. Two of these serve as asymmetrical sheet winches and winches for the available running backstays. (1) Asahi #42 winch on mast for jib and asymmetrical halyards. Below decks an Antal "linedriver” winch easily raises and lowers the daggerboard.
Custom stainless bow and stern pulpits with double lifelines on the foredeck. Aluminum stem and anchor roller fitting with anchor locking device houses a Model 45 24 lb. Max Anchor. Self balling anchor & rode deck locker holds anchor chain and 200 foot nylon rode with ample room left over for more rode, another anchor, or a drogue. Mooring and docking cleats. Fairleads and turning blocks for all deck lines. All control lines are led to the cockpit and well organized for simplified single or double handing, Nets are custom offshore 3/8” coated polyester open net (Sunrise Yacht Products 2018) and cover interbeam spaces as well as the areas outboard of the cockpit.
Cockpit and Steering
The cockpit is partially protected by a hard dodger/windscreen. The dodger arch will support the boom (or a person) if required. A foldable bimini provides shade and rain protection for the rest of the cockpit. The cockpit is 6 6” long and can be open transomed or closed . This makes boarding, loading, and swimming access very convenient. The aft end of the cockpit can be securely closed off with rugged drop boards which have large one way self draining scuppers. The companionway can be closed with three drop boards which are fitted with keeper lines to prevent lossin rough conditions. Attachment points for jacklines are installed.
An Edson bulkhead steerer with leather covered “destroyer" wheel and wheelbrake is fitted to the forward cockpit bulkhead on the starboard side. Instruments, engine panel, and controls are conveniently located at the steering station. A Raymarine 4000Mk2 wheel pilot autopilot is installed at the wheel. The steering system drives stainless chain and wire via bronze sheaves to the Edson radial drive at the stern. All steering components are immediately accessible through easily removed panels or covers. Wheel gearing produces 1.2 turns lock to lock and steering is responsive, easy, and sure under all speeds and conditions.
Ventilation and Heating.
Four Lewmar deck hatches provide light and air to the forward cabin, head, and saloon, Four Vetus aluminum opening ports are placed in the galley, nav station and saloon. Two deck mounted solar powered fan vents also move additional air in the forward cabin. A large Lewmar hatch is located in each float deck to access substantial stowage therein and all closed float compartments have inspection ports.
Heat is provided by a Force 10 vented LP Gas heater located in the main cabin and this unit has provided ample warmth in the worst weather Maine can produce, at least through November.
Tankage and Plumbing:
All tanks in the boat are fiberglass/epoxy lined, integral with the hull or in glass reinforced epoxy coated plywood. Tanks are appropriately baffled and vented. 90 gallons of water are held in two 45 gallon tanks with internal fill and inspection panels, Either tank is selectable, leaving the other for reserve. Holding tank is approximately 30 gallons, and serves a Lavac vacuum pump toilet fixture. The tank will empty by gravity to the water or can be closed for later pumpout at the deck. Fuel tank holds approximately 35 gallons of diesel. All hoses and fittings are of top quality and all through hulls to the water are fitted with Forespar Marelon ball valves.
Fresh water is fed to the galley sink and to the head sink by a pressure system. Hot water is provided by a PrecisionMate ShowerMate M-550 (2019) installed in the head compartment.
Diesel fuel is filtered by both a primary Racor filter/water separator and a secondary Yanmar fuel filter. A raw water intake strainer is installed, The freshwater cooled Yanmar 27 HP engine was installed in 2020 and has 50 hours of use. A "PSS" shaft seal is fitted to a 1" Aquamet shaft which drives the Martec folding propeller (serviced by Martec Apr 2021). All engine and drive components, including the fuel tank, are easily accessed through two conveniently placed hatches. Start battery is an Odyssey Extreme 34M battery (2018)
Performance under power is excellent, both in forward and reverse. With a clean prop and bottom and daggerboard up, top speed approaches 9 knots. Best fuel economy is found in the 6 to 7 knot range.
Two 110 amp hour 12 volt DC Firefly Carbon Foam deep cycle batteries (2019) are recharged by the engine alternator and 2 Genasun GV-10 charge controllers (2019) each powered by a 100 W solar panel (2019) mounted on the aft crossarms. A Victron BMV-712 Smart Battery Monitor (2019) allows easy monitoring of battery state of charge. Both house and start battery circuits are switched at helm using Blue Sea remote battery switches (2019).
The house battery bank feeds a Paneltronics circuit breaker panel with accurate amp load and battery voltage guages. Electrical requirements are well divided among 20 appropriately sized circuit breakers with spares available for additional equipment as desired. AlI wiring is fully tinned marine grade with captured terminals. Cabin, navigation, and deck lighting fixtures are well placed and of high quality. Red night lighting is available in key functional areas.
Kachina’s navigation electronics have also been fully upgraded in 2018. A Raymarine Axiom 9 Multifunction Display is mounted on an adjustable RAM mount at the helm. Also at the helm are Raymarine i70s Instrument Display and P70S Autopilot Control Head. A Raymarine ST4000 Mk2 Wheel Drive unit mounted on the wheel is driven by an ACU-100 Actuator Control Unit and EV-1 Attitude Heading Reference Sensor which are mounted below decks. Depth, water speed and temperature, and wind speed and direction sensors are networked using the Raymarine iTC-5 Converter. A Standard Horizon GX2150 VHF/AIS Receiver with mast mounted antenna is in the nav station and is connected to the network to show AIS data on the Axiom 9. A Standard Horizon RAM3 Remote Microphone is mounted at the helm. A Raymarine Quantum 2 Q24D Doppler CHIRP Radar (Mar2020) is installed on the mast and integrates with the Axiom 9. Also in the nav station is a Digital Yacht iKommunicate Gateway that provides NMEA data on a WiFi network.
The interior of the boat is aesthetically well divided amongst off white polyurethane paint, varnished red cedar, ash trim, teak and holly soles, and dark green fabric cushions of marine quality velour. Stowage spaces are well distributed, ample, handily arranged, and secure throughout the boat.
From forward to aft the layout is as follows:
A large stowage area forward of the V-berth, and under the anchor locker on deck, provides room for bulky and infrequently used items. This space is accessible from the foot of the V-berth through a removable panel. Another large stowage area is below the V-berth.
The forward cabin is comprised of the 6’6” long by 5' wide double berth with adjacent dressing area which has standing headroom and lockers for stowage of gear and clothing.
Aft of the double cabin is a door to the head compartment. A marine Lavac toilet is to starboard with holding tank behind; sink and counter to port with cabinets over and under. The head sink faucet handle extends to provide a showerhead in the head compartment.
The main cabin features two settees, 6’ 1" and 6’ 8" in length, with a 40”X40” dropleaf dining table between. Stowage under the settee is accessible from the hinged front panels, you don't have to pull the cushions or wake someone up to get into these lockers.
To either side of the settee, under the cabin sole are the two 45gal water tanks. Aft of those tanks is the icebox with an Isotherm 2050 SP Water Cooled Refrigeration Component System (May 2018).
The galley is aft and to starboard. The counter is 5’ 2” long by 29” deep. In the galley counter is a deep stainless sink, work space, and the gimballed 2 burner Force 10 propane stove with oven and broiler. There are lots of bins, drawers and cabinets over and under the galley area.
Opposite the galley on the port side is the nav station with a 24”x 32” lift top Formica table with stowage under. A comfortable seat facing forward serves the navigator. Over the nav table are nav. Instrument and storage. Aft of the nav station a wet locker is located adjacent to the companionway steps.
