2024 Rizzardi In Five

The boat is built in three parts: hull, deck and superstructure.

The boat is built in GRP. The first layers of the hull lamination are made using fiber glass (type E) impregnated with vinyl-ester resin, which grants a high osmosis prevention.

Isophthalic polyester resin, approved by the major Classification Registers, is used for the lamination of the remaining parts.

The boat hull structure has a mix of longitudinal and transverse stringers for the bottom and PVC core sandwich for the sides.

Sandwich construction is used for the deck and the superstructure.

All the structural bulkheads are made with PVC core sandwich or marine plywood approved by the Italian Naval Register. The hull bottom is deep V with 15° DEADRISE at the stern.

Main characteristics

The electrical system is built in accordance with the current legislation. The rated voltages on board are:

• 220 V AC mono-phase, 50 Hz, for motive power circuits.

• 24 V DC for lights, navigation instruments and for small motive power circuit.

• 12 V CC for the generator start-up circuit.

All the main system lines are connected to the main electrical panel. The lines are protected by magneto-thermal switches properly.

The electric cables are “not propagating the flame and reduced emission of smoke and toxic gases”. FROR cables are used for the

220 V AC section and double isolated cables for the 24 V DC section. The cross section of cables is properly sized with respect to the maximum allowed current load.

The electric cables are assembled in self -extinguishing closed PVC.

The ground system consists of a dedicated line that collects the grounds of the water inlets, the supports, and all the 24 V equipment. This line is connected to a zinc anode fitted on the transom.

The engines and electronic control units have a separated ground system connected to a second zinc anode fitted on the transom.

The electrical generator, the electrical panel and all the 220 V ac utilities are connected to a porous plate.

Integrated monitoring and control system

A section of the system is controlled through an integrated monitoring and control system. The system is controlled with touch.

screens fitted on the dashboard. All the utilities are protected by virtual magneto-thermal and fuses. Manual control can be.

operated in case of emergency.

AC power sources

control panel and hour-meter.

entertainment and the cabin sockets.

Audio/video system 

The integrated audio system includes a main unit that controls dinette and cockpit, with the possibility of adjusting the volume.

independently in each area. There are No. 2 speakers in dinette and No.2 speakers in the cockpit.

The video system includes a digital terrestrial antenna, a TV in the owner’s cabin and predisposition for a TV in the cockpit.

Note: Electronics and entertainment systems may vary depending on the evolution of the market.

BILGE PUMP SYSTEM

The bilge system allows pumping from each watertight compartment of the boat using the least 2 separate systems. The main suction of the bilges, and the outboard discharge, is carried out through submersible electric pumps activated by water level.

sensors, manual activation is allowed from the dashboard and from the main electrical panel; an electric pump is installed for each watertight compartment.

The centralized bilge pump system has a suction box in each watertight compartment, the selection is made through the collector located in the engine room.

The bilge alarm system provides, for each compartment, a lower sensor that automatically activates the submersible pump and a second sensor placed in a higher position for a bilge alarm on the display at the dashboard.

In the engine room an emergency system is also provided by suction from the engine cooling circuit.

FIRE FIGHTING AND SAFETY SYSTEM

For the protection of the engine room is installed a manual/automatic system. The manual activation of the system is done trough.

a handle located in the cockpit. A temperature sensor in the engine room automatically activates the system. When the system is discharged a loud and visual alarm is activated. The fire is detected by smoke and temperature detectors, the alarm is displayed by the helm station. The boat is equipped with portable powder extinguishers located according to the Safety Regulation.

FUEL SYSTEM

The fuel system consists of alloy tanks with a total capacity of 2000 lt.; the system is provided with electric and optic level gauges.

Deck fuel fillers are located on each side. All the houses are certified for fuel use.

FRESH WATER SYSTEM

Fresh water is supplied to the system by a 550 liters structural tank located in the lower deck.

In the engine room is located a 24Vcc water pressure pump. An electric water heater delivers hot water to the system. A shore water connection (OPT) allows fresh water supply to the system.

BLACK AND GRAY WATER SYSTEM

Waste waters from showers, washbasins, galley are collected in a structural gray water tank with level sensor and emptying pump.

The WC flushing system is with sea water. The waste waters are collected in a black water holding tank or discharged directly.

SEA WATER SYSTEM

The main sea water inlets are in the engine room bilge. Each inlet is fitted with a valve and a stainless-steel filter; Sea water is supplied to the main circuits on board, the engines cooling systems, generator and air conditioning. The cooling system of each engine is also used to cool the reversing gear and the raisers of the engines exhaust system.

MAIN ENGINES EXHAUST SYSTEM

The exhaust pipes of the main engines are made with AISI 316L Stainless steel and sized according to the engine manufacturer’s directions. The main exhaust pipe is connected to a properly sized muffler which is connected to the stern of the boat, under the

swimming platform, through a GRP rigid pipe. The engine exhaust pipes are insulated with ceramic therm-insulating material.

AIR CONDITIONING SYSTEM (OPT)

The air conditioning system has a 24.000 BTU cooling capacity, and consists of a cooling unit, treated water and sea water circulation pumps, located in the engine room. The fan coils, with automatic and independent control and regulation, are positioned in each cabin and in the dinette. The system can work as a heat pump.

HYDRAULIC SYSTEMS

Steering system: the steering system, integrated with the transmission, is power assisted through a high-pressure pump installed on the PTO of the main engine. Steering is controlled through a pump connected behind the steering wheel.

Trim and Flaps: a single hydraulic control unit allows adjustment of the surface propellers immersion (up - down) and of the flaps for dynamic trim of the boat.

The gangway is managed with a single hydraulic control unit. A second hydraulic control unit provides for the access door opening to the engine room and the movement of the Hard top.

All the control unites are in engine room.

VENTILATION AND EXHAUST BLOWERS

The ventilation of the engine room is sized as required by the engine and generator manufacturers.

The forward engine room bulkhead is insulated with sound-absorbing and sound-insulating materials. Hull sides are insulated with multi-layer quilt or similar material.
