Nimbus 305 Coupé is a cruiser of 10.07 meters maximum organized around the Smart Speed hull, the asymmetrical Sidewalk passers and a protected lounge. The project declares an operating range optimized from zero to 22 knots, without a clear plan threshold, and combines this setting with diesel or electric motors. The configuration is therefore evaluated as a system: visibility, ventilation, side access, energy and tanks must remain consistent with the cruise program.
Main data and controls
The length of the hull is 9,74 meters and the maximum 10,07. The maximum beam is 3,25, the fishing 0,90 and the maximum height 3,65. The declared weight is 4,100 kilograms; the maximum allowed 5.697, with a maximum load of 1,600. The separate exemplar must indicate propulsion, batteries, tanks and optional.

Carena Smart Speed from zero to 22 knots
The hull is developed to maintain continuous behavior throughout the declared range, avoiding abrupt transition. This allows you to adapt the gait to the sea without pursuing the plan. The advantage must be checked with measures: turns, GPS, consumption, noise and layout to multiple systems, in opposite past. Load, bottom and helix can significantly change the result.
Asymmetrical sidewalk
The Sidewalk focuses a broader passer on the right side. The choice facilitates the movement from stern to bow and allows to exploit more internal volume. Safety and function depend on antisdrucciolo, tientibene, thresholds and position of the tops. The verification is carried out with crews and parabords already arranged, because the passage must remain really free during the mooring.
Sliding door to the bridge
The large sliding door directly connects the driving position to the passersby. Allows the helmsman to go out and maneuver standing along the side. Guides, locks and seals are tried repeatedly. The door must block in navigation and not create infiltrations; when it is open, it should not reduce visibility or become an obstacle.
Curved windscreen and visual field
Pasted windows and curved windscreen create a panoramic view. However, they control mountings, reflections, weaving and disappearance. The test should be done with low sun, rain and reduced indoor lighting. The sitting and standing position must maintain legible instruments and sea. A large glass does not guarantee the absence of blind sectors alone.
Vetrate roof and natural light
The living room receives light from a large glass roof and upper doors. Configuration increases brightness but requires heat, condensation and seal control. Gaskets and drainage must be accessible. The opening, the emergency procedure occurs, and it is observed if the sun creates reflections on the bridge. Observation and ventilation must be defined in separate.
Salone and dinette for four
The dinette welcomes four people and turns into a double bed. The table can be lowered in cocktail position with cup holders. There are basics, hinges and stops in each trim. The transformation should not block doors, electrical panels or via exit. Bearings and extensions require a dry and identified storage.
Kitchen with gas top
The declared kitchen uses a gas heated glass top with integrated ventilation, Corian top and 65 litre refrigerator. An additional refrigerator or freezer compartment is available under the sofa. Gases, drains and power supply require separate controls. Ventilation, interception, closures and absorptions occur, avoiding to consider standard what is optional.
Two cabins and 4+2 beds
The 305 Coupé declares two cabins and four beds plus two in the dinette. The capacity should be assessed in relation to ventilation, privacy, water and storage. Mattresses and funds must be able to dry. Each bunk is tried with people who will use it; luggage and linen must not obstruct inspections or exits.
Volvo Penta D4-270 axis
The diesel engine is a Volvo Penta D4-270 with axis line. The control includes motor, inverter, seal, axis, supports and propeller. The response to multiple regimens is measured and vibrations and temperatures are observed. Access for filters, impellers and ordinary maintenance must be practicable without disassembling furniture.
Alternative Torqeedo Deep Blue
The official page includes Torqeedo Deep Blue. Electricity assessment requires delivery configuration data: battery, charging, cooling, measured autonomy and reserve. You cannot transfer values from another specimen. The test includes insulation, alarms and procedures, with qualified personnel for high voltage components.
250 litre tank
With diesel the declared capacity is 250 liters. Tape, vent, filters and pipes must be accessible and odor free. The autonomy is calculated on the usable liters and on the measured consumption, keeping reserve for deviations and the contrary sea. A register of supplies, hours and miles builds the profile of the specimen.
Fresh water and boiler
The capacity of fresh water is 150 liters and that of the boiler 20. Pumps, autoclaves, valves and heating are tested with all utilities. We are looking for leaks, pressure drops and abnormal temperatures. Consumption must be related to six beds and the real program. The winter drainage must be provided by the maintenance plan.
80 litre waste tank
The 80 liters declared require vent, indicator and ground suction correctly installed. Pipes and clamps must be inspected. Persistent odours often indicate inadequate maintenance or ventilation. The check sequence identifies valves and connected utilities, avoiding incorrect maneuvers in port or during remittance.
Electrical system 12 and 230 volts
The card indicates 12 and 230 volt networks, a 77 Ah starter battery and a service counter configurable from three to six 80 Ah batteries. The distinction must specify the actual number. Chargers, protections, sockets and masses are controlled. Refrigerators, lights, pumps and accessories are tested simultaneously to detect voltage falls.
Category B for eight people
The EC category is B and the maximum declared eight passengers. The exemplary certificate must be consistent with engine and equipment. Eight people influence thirst, lounge and steps. Before leaving, you will assign vests and seats, keeping the side door and free exit routes.
Cabin and blanket inspection
They control gelcoats, joints, windows, roofs, pulpits and bitten bases. Doors and doors must close evenly. In the living room infiltration and condensation are sought; in the technical compartments wiring, corrosion and unbridled pipes. Photographing each space before loading equipment creates a useful reference for future interventions.
Maneuver test
The side surface of the coupe increases the sensitivity to the wind. The test starts at low speed, with triggers, steering and reverse response. The side door allows the timoniere to observe the dock, but does not replace a clear procedure and communication. Any aids are tested for absorption and limits of use.
Testing in navigation
Cold engine levels, tensions and feel are recorded. The acceleration proceeds by steps, annoting turns, GPS, consumption, noise and visibility. They evaluate virata, scie and response of the hull between displacement and 22 knots. After the return, motor compartment, doors, roof and water or movements are controlled.
Documentation and delivery
Number of hulls, category, engine, propeller, batteries, kitchen and accessories must coincide with contract and manual. Tanks, indicators, pumps, refrigerators, table and bunks are tested. For use, it serves history, hours, invoices and documentation of changes. A configuration not accurately described is not verifiable.
The maximum declared load is 1,600 kilograms and must be read together with the maximum permitted weight of 5.697 kilograms. People, luggage, supplies, liquids and accessories installed contribute to the budget. The delivery controls then record the weight and position of the added elements, especially batteries, chain, equipment and equipment. An electric configuration with six batteries services is not the same as the one with three: it changes the available capacity, but also mass, charging and maintenance. The certificate and the distinct must describe the real specimen, not a theoretical combination of options.
Energy balance of services
The declared service counter can include three to six 80 Ah batteries; therefore the actual number is the first data to check. A list of 12 volts and 230 volts is built, with absorption, hours of operation and charging. Main refrigerator, possible according to refrigerator or freezer, pumps, lighting and tools must be evaluated together. The dock test controls chargers and sockets; the one without external power measures the voltage drop. Cables, fuses and ventilation of the battery compartment must correspond to the delivered configuration.
Ventilation and closed volume management
The Coupé concentrates living room, kitchen and dashboard under large glass surfaces. The comfort therefore depends on the combination of roof doors, side door, ventilation of the cabins and possibly installed systems. During testing, condensation, air exchange and temperature are observed with more people on board. The gas kitchen requires a separate procedure: active ventilation, accessible interception and control before closing the boat. Even the obscurity of the roof and the protection of the furnishings from the sun must appear in the distinct if present.
checks for the cruise program
Before a route you connect autonomy, water, waste, energy and weather to the real number of people. The 250 liters of fuel, the 150 of water and the 80 of waste are declared capacity, not guaranteed. A measured consumption register allows you to build consistent margins with your own crew. The verification includes availability of ground drains, supplies, essential spare parts and accessibility of plants. The Sidewalk facilitates maneuvers, but peaks, parabords and equipment must be prepared without occupying the right passage.
Technical judgement and ideal shipowner
Nimbus 305 Coupé is consistent for those who navigate at variable speeds, want protection and appreciates direct side access to the bridge. Sidewalk, Smart Speed and bright lounge are parts of the same project. The suitable owner prefers ease of management, autonomy and maintenance compared to the tip. The choice between diesel and electric requires specimen data and a documented test.
