DESIGN

Deva was designed and built in 1992 by OSTAC Yachts Australia (builders of the F-31 trimaran), and is a modified Robin Chamberlin design. She is 11.6 m x 7 m (38' x 24'), very strong, fast and light. The construction is composite - Diviniycell core vacuum bagged with Biax and Triax laminate skins. Daggerboards provide excellent upwind performance, whether racing or cruising.

Originally intended for the Australian AMOC Championship series, she also has a bright, airy bridge deck cabin with small galley up and excellent ventilation for the tropics. Deva is an outstanding combination of a racer/cruiser with long-range cruising capabilities.

We have lived aboard cruising worldwide for 16 years, and have covered over 25,000 miles since leaving Australia in 1994.

CONSTRUCTION

GENERAL

Deva’s hulls were built in a female mould from 20 mm Divinycell rigid closed cell foam, sandwiched in triaxial glass. The structural beams and bulkheads of the yacht are built from glass over ply or composite Divinycell foam sandwich and have created an extremely rigid structure. Her decks, cabin and some furniture are built from 20 mm foam sandwich.

The exterior lay-up is 30 oz triax using vinylester resin.

The interior lay-up is 20 oz triax using vinylester resin.

Watertight compartments in the bow and stern sections provide an extra safety margin.

EXTERIOR FINISH

Deva’s topsides are finished in gloss white International Perfection 709 LPU; with a black swoosh stripe and non-skid decks. She has a copper epoxy barrier coat with two coats of Triton ablative antifouling on top. Paintwork was new January 2010. Two levels of 6 mm tinted Lexan polycarbonate windows are fitted in the salon and topsides. Forward there are two ‘Spectra’ bow nets woven and separated by a Divinycell foam sandwich catwalk. Aft, stainless steel davits support two solar panels and the dinghy.

LAYOUT AND INTERIOR FINISH

ACCCOMODATION

Double berths in both hulls are located on either side of the bridge deck settees. There is approximately 5’ 10” headroom alongside. Interiors are finished in a combination of high gloss white LPU paint and a soft gray headliner carpet. The fore/aft seats of the dinette may be converted to two single berths.

SALON

A dinette for six is central in the bridge deck. Two settees seat three each. A white laminate table is fixed to the main bulkhead at the forward end. Upholstery was new January 2010. There is full-seated headroom in the salon. Underneath the settees are 4 storage compartments for food, kitchen implements, tools etc. Shelves above and parallel to the settees provide a space for instruments and navigation tools. Two companionways aft provide excellent access from the bridge deck to the cockpit. The entire salon space is sprayed with a high-gloss white LPU paint for a bright and clean finish, with varnished teak trim. Headroom in this space is 140 cm.

GALLEY

The galley is located amidships against the aft salon bulkhead. To starboard, and set in a solid teak counter top, is a stainless steel sink. It draws from the designated 160-liter galley/drinking tank with a Whale foot pump, and Whale Elegance faucet. To port is a two-burner gas stove with griller and oven. Cooking and food preparation is done seated at the salon table with excellent access to the stove and sink. This also provides a secure perch in a seaway. Underneath the sink and oven there is storage for dishes and cleaning supplies in two cupboards. A large, insulated cold box is immediately outside the adjacent companionways. No refrigeration. The Plexiglas windows aft of the sink and stove are removable to allow excellent ventilation and access to the cockpit. LPG is plumbed from a 10 kg bottle in the port forward deck locker with copper pipe.

BATHROOM/HEAD

A Jabsco marine toilet is forward to starboard. White LPU paint and varnished teak trim give a bright, easy-to-clean finish. There is a sink with convertible shower that draws from a designated 250-liter bathroom tank via a Whale foot pump and Whale Elegance faucet. Ample storage is built in to shelves under the sink and a compartment behind the mirror above the sink. No holding tank.

WALK-IN CLOSET

A full sized walk-in closet is located port forward. There are five shelves along the starboard side, and a hanging locker forward. The space is upholstered in soft gray headliner carpet.

VENTILATION

Ventilation is superb with four forward-opening hatches – one on either side of the mast over the dinette area, and one over each double berth. These allow excellent airflow and keep the boat cool and comfortable in tropical climates.

COCKPIT

A large cockpit extends across behind the salon and is separated into three sections. They comprise two steering stations and a central work area. Tiller steering from two outboard cockpits gives the helmsperson good visibility and crew contact as well as placing mainsheet close at hand. Visibility is excellent when standing in the central cockpit and also when seated in the outboard cockpits. Halyard and headsail winch positions are on top of the bridge deck. Traveler, mainsheet and spinnaker winches are handled from either the outboard or central cockpits. Instrumentation is on a central rotating cluster. Two steering compasses are bulkhead mounted at each steering station.

DEDICATED STOWAGE

Stowage is ample.

2 x interior hull compartments stretch underneath the side cockpits

2 x sail lockers in the bows

2 x aft lazarettes in hulls with access to rudder/tiller assembly

4 x bridge deck hatches – 1 LPG locker, 2 anchor lockers, 1 sheet locker

2 x cockpit lockers that house batteries and fuel jugs

2 x cockpit cubbies in aft beam for miscellaneous items

2 x cockpit cubbies in side cockpits for sundry items

RIG

MAST & STANDING RIGGING

The mast is a 17 meter (55 ft) tapered Allspar section, finished with white LPU. It is a moderately pre-bent ¾ fractional rig equipped with double swept-back spreaders and a forward jumper and masthead jumper struts. This three-stay rig is modern, powerful, yet easy to handle. A prodder off the center of the fore beam is used to set the asymmetric spinnaker. All stays were new in March 2010.

DECK GEAR

2 x Barient 22-39 self-tailing winches are located on the cabin roof. They control halyards and reef lines lead through Spinlock rope clutches.

2 x Barient 27 primary winches control the headsail sheets on the cabin roof.

2 x Barient 24-45’s control the mainsheet.

2 x Barient 21-33’s control the traveler.

2 x Barient 10’s control the daggerboards.

MOTORS

Two 4-stroke electric start remote control outboards are installed immediately inboard of each hull on the aft beam. Economical and quiet they eliminate all skin fittings and underwater drag associated with inboard diesel installations and provide plenty of power to motor into a sea at 6 knots or better.

PERFORMANCE

Since 1994 Deva has spent over a decade blue-water cruising, covering 25,000 nautical miles. She had refits in 1997 and 2010. She has safely navigated halfway around the world crossing the Indian and Atlantic Oceans. Deva is an exceptional vessel, perfect for the performance-oriented sailor who also wants offshore capability. She is suitable for racing, cruising or both.
