AZIMUT YACHTS - AZIMUT 43 S

The Avigliana-based yard extends its sport cruiser "S" range - which already includes the 62, 68, 86 models - with the 43 footer presented last year at Genoa Boatshow.

Stefano Righini's model combines spacious interiors, animated by asymmetrical windows, with an aggressive and bright outside line. The "family feeling" is evoked by several features such as: the square window on the hull - a common feature to all "S" yachts -, the mirrored inverted fin-shaped windows on the superstructure, the hard sportop ending with the typical Azimut tail and the wine-red stripe. Inside, where cabins are clearly separated by the living area, Carlo Galeazzi's décor is sober and modern, and harmoniously combines the light and bright natural fabrics with the dark tones of wengé paneling, furniture and flooring. The electrically operated sportop contributes to the airy and bright atmosphere of the saloon. Thanks to the squared bow, hardly noticeable from the photographs taken under way, the master stateroom is very comfortable and the bow area is quite large.

The real innovation of the 43S is deep inside the boat: the Volvo Penta IPS propulsion system with engine, reverse gear, steerable propulsion unit, counter rotating propellers and integrated steering gear. This system offers unparalleled advantages such as: compact engine and propelling unit, simplified installation and improved efficiency thus reduced fuel consumption with extended range. The disadvantages are considerable trim variations when turning and the need of fine-tuning flaps for optimal trim. Nevertheless, the 43S is an amusing boat, both under way as well as in harbor where, thanks to the counter rotating propellers, mooring is quite similar to car-parking.

CONSTRUCTION CHARACTERISTICS

Hull: deep-V hull with longitudinal steps and 14° deadrise
Hull construction material: infusion-laminated GRP hull, monolithic bottom and sandwich topsides. Vinyl ester resins used for outer layers against osmosis and polyester resins for the rest; hull strengthening in way of IPS transmission so that in case of a collision the leg lifts with no hull damage (similarly to a fuse). Marine plywood and foam sandwich bulkheads
Bow area: stem fitting with 21kg-anchor and 75m-chain with self-draining anchor peak and 1,000W/24V windlass, stainless steel fender container fitted on the railings, ample sun bed
Cockpit arrangements and fittings: teak cockpit with U- shaped settee and table that converts into a sun bed, two side storage compartments and fitting for manual pump
Characteristics of the aft platform: accessible from cockpit by a door; may be lowered below water level to launch a 2.5m tender; capacity of 400 kg and fitted with stowaway swimming ladder; access from the cockpit to the 2.66 m gangway is by way of two steps.

INTERIORS

Layout and characteristics: the master stateroom is forward, it includes the double bed and underlaying drawers, two hanging lockers and side shelves; two fixed windows on hull side and an opening hatch on deck provide plenty of light. The en suite bathroom includes rounded Perspex shower stall, electric WC, crystal glass basin, cabinet with mirror and an opaque skylight for natural lighting. The second bathroom and the guest stateroom may be accessed by the corridor. This bathroom is similar to the master's one but it is not as bright. The guest stateroom, located under the wheel station and saloon has headroom in the treading area. The cabin includes twin beds, a hanging locker and drawers. The lower deck includes the galley as well. On the main deck there is the saloon with opening sportop, electrically operated table, sofa and opposite two armchairs; an optional sofa convertible into double berth may be requested
Helm station: raised, with two seats with adjustable backrest; dashboard with analog instruments for water temperature, oil pressure, rpm counter, hour counter, tiller angle, fuel indicator, water indicator, Tridata, radar, GPS, auto pilot, Volvo Penta displays for engine control, chain counter, bow thruster control, flap indicators
Chart table: with Perspex counter to port of dashboard
Galley: three ceramic hobs with pot catches, extractor, sink, 130 liter refrigerator, stainless steel top, cabinets.

FITTINGS

Standard fittings: Inboard Performance System transmission, aft platform, wine-red stripe on hull, electronic engine controls, chain counter
Optional fittings: Charme decor, forward sunbed cushions, saloon curtains, teak cockpit, teak swimming platform, forward maneuvering lights, Raymarine E120, Fishfinder DSM300, Raymarine antenna 48nm, 13kW DB Kohler generator, tropical BTU 40,000 air conditioning system, bow thruster, double Racor filters, single Racor filter, safety box in master stateroom, stainless steel fender holder, 130 liter refrigerator and 50 liter freezer, refrigerator in cockpit, teak sink cover, saloon sofa convertible in bed, Galeazzi-designed table lamp, automatic feeder for refrigerator, 2 sets of towels with logo, a set of pots, automatic firefighting system, side access doors.

IMPRESSIONS

SEA AND WEATHER CONDITIONS DURING BOAT TESTING
Wind: 15 knot wind with gusts
Sea: slightly moderate.

PERFORMANCE (with full water and fuel tanks and 5 passengers)
Time needed to reach planing speed: 8.6 seconds
Minimum planing speed at 2,300 rpm's: 13.4 knots
Maximum speed at 3,450 rpm's: 31.3 knots
Cruising speed at 3,170 rpm's: 27.5 knots.

EVALUATION OF PERFORMANCE
Seakeeping ability, turning and behavior on waves: good; when turning the boat tilts considerably because of IPS propulsion unit
Wheel response: the integrated Volvo Penta electronic controls offer a firm and progressive response; a device limits the turning angle of the propeller/rudder set in proportion with speed
Helm station: for IPS trim, flaps must be adjusted by a few degrees to keep the boat on a horizontal plane and to have good visibility
Docking maneuverability: good, very similar to automobile parking, adaptation to IPS system is necessary.

EVALUATION OF COMFORT AND FUNCTIONALITY

Deck: the living area of the cockpit is covered by an extension of the sportop and includes a sofa with table convertible in sunbed; second sunbed forward. Interiors: the interior décor signed by Carlo Galeazzi is in natural fabrics and wengé wood; even though the lower deck has small living spaces, the layout offers a good level of privacy
Passengers' comfort: the boat is very comfortable for 4 persons; in an emergency, 2 additional guests may sleep in the optional sofa convertible in bed in the saloon
Galley: extremely functional
Bathrooms: comfortable with electric toilets and round shower stall; the master bathroom is very bright
Engine room: very compact with three different accesses: from the saloon, from the cockpit (here levels may be checked) and from under the aft sofa (here access to transmissions is also possible)
Electric switchboard and plants: shore power, (optional) generator, engine and dashboard switchboards, 24V/150Ah domestic battery, 24V/150 Ah engine battery, shore power 50A battery charger, generator 10A battery charger.
