The Siren 60 carries a semi-dislocating logic in 19,45 meters, with two levels of Volvo, V-drive, 3,600 liters of diesel and declared autonomy of 800 miles to 10 knots. The configuration changes significantly between D11 from 670 hp and D13 from 900 hp, especially for mass, speed and thermal budget.
This guide is not a test at sea. Organize official data and verifications to be entered in order, testing and delivery. The goal is to choose engines, layouts, energy and accessories according to people, shaves, ports and miles, without attributing to the exemplary unmeasured results.

D11 or D13
I D11 promise a lighter configuration; the D13 add 230 hp per side and about 800 kg to the mass declared full load. The choice must consider typical load, sea, usual speed, assistance and total cost.
Testing builds turn curves, speed, consumption, load and temperatures. The 23,5 nodes declared with D11 and 25,8 with D13 are project references, not automatic results.
V-drive and accessibility
Engines, ZF 325 IV, V-drive, axes, propellers, cooling and drains form the propulsive chain. Freshmen, reports and propellers must coincide with the file.
Filters, impellers, belts and valves must be reached. After the test you control alignments, oils, supports and drawings.
Carena and 800 miles
The Frers hull works between displacement and fast. The 800 miles to 10 knots must be read with conditions, load and reserve declared by the manufacturer.
The minutes record sea, wind, temperature and tank levels. Only measured consumption allows to plan a route of the specimen.
Three thousand six hundred liters
Nominal and usable capacity does not match. Fund, reserve and generator reduce the fuel available. Specs, returns, valves and filters are mapped.
Indicators are calibrated at multiple levels. Measured reinforcements build a curve and help identify differences between reading and real quantities.
Cover configuration
Prua, passers-by, stern and flybridge have distinct configurations for shaving and navigation. Tables, cushions and covers require hold and hold.
Drainage, anti-slip surfaces, battalions and tientibenes feel wet. The view from the bridge is verified with people and tents present.
Semi-dislocated profile
The high volume must be balanced by a credible weight distribution. Tender, batteries, stabilisation and accessories enter the separate with mass and position.
Diving and trim are detected at different levels of tanks. Correctors should not mask a static imbalance.
Poppa and sea access
Mooring, platform, passage and storage converge to aft. The tops must also be managed with furnishings in use.
Actuators, scales, drains and manual controls are tested for cycles. The tender must respect the scope and geometry of the configuration.
Flybridge
The flybridge adds bridge, chairs and shadow to the highest area. Massage and taking the wind must appear in the loading floor.
Visibility, transfer of controls, stops, drains and procedures with an unavailable display or station.
Exhibition and kitchen
The main bridge connects kitchen, lunch and aft. Climate, refrigeration and cooking are tried together with people and sun.
Temperature, humidity, absorption and noise are recorded. Drawers and luminaires have stopped and do not block escape routes.
Bridge and networks
Multiple displays can share sensors and power supplies. A map distinguishes GNSS, radar, AIS, autopilot, VHF, alarms and engine data.
It simulates the loss of a display and a source. Configurations, versions and passwords are delivered to the owner.
Kitchen and electric budget
Plates, oven, refrigerators, suction and sink add energy, heat, water and drains. They try at the same time.
Every device must be isolated. Ventilation and drainage remain accessible without dismantling permanent furnishings.
Six beds plus crew
Three cabins and a crew place require a realistic budget of air, water, waste and linen. Beds and luggage must not block escape routes.
The contractual layout must coincide with doors, cabinets, bathrooms and technical panels of the specimen.
Shipowner's Suite
Noise and vibration are measured with engines, generator, climate and pumps in repeatable combinations. The values become baseline.
Condensation, obscuring, ventilation and sealing are controlled. The access behind the furniture must remain practical.
Cabin guests
Each bed place is tried with sockets, lights, ventilation and boots in use. Oblay and man passes receive a water proof.
More utilities are operated to check pressure, hot water, odours and waste in the bathrooms.
1800 liters of water
Capacity is divided for people and days. A possible dissalator enters the budget with scope, quality, filters and consumption.
Pumps, boilers and indicators are calibrated. Operating thresholds define when producing water or returning.
Ref
The 450 liters of black and 225 grey require levels, vents, valves and documented discharges. Alarms are activated on trial.
The procedure must respect the navigation area and indicate who authorizes transfer or emptying.
Energy and failures
The budget separates navigation, rail, night and emergency. Batteries, chargers, inverters and generators are tested under load.
You isolate a source safely to check what remains available. Schemes and protections must coincide with labels.
Stabilizers and fixtures
The choice of fins or gyroscopic stabilization changes weight, volume, energy and maintenance. The fins add appendages and actuators; a gyroscope requires space, cooling and a structure capable of absorbing loads. The capitulate must report model, mass, position, limits and performance expected in terms of use.
The test compares active and disactive system with route and sea noted. Alarms, exclusion and reboot checked. Stabilization and concealers must not impart conflicting commands, while the commander retains a procedure for degraded operation.
Tender, lump and mobile loads
The dinghy is chosen together at the reach of the platform, storage geometry and steam system. Real weight with engine, fuel and equipment must fall into the limit, not only the vacuum shell. Cot, restraint points and interference with passage and mooring are controlled.
Varo and recovery try with people in the planned positions. Actuators, winches, end of race and manual command must remain accessible. SUPs, bicycles and water toy receive their own boots, avoiding blocking pumps, valves or emergency routes.
Air conditioning and condensation
Vetrates, flybridges and kitchen produce different thermal loads. The test is carried out with sun, people and appliances active, measuring temperature and humidity in the living room and cabins. Air doors and noise are recorded at different speeds of fans.
Condensed discharges, tanks and pumps are inspected after hours of operation. A wet panel or a persistent smell is not treated as aesthetic detail: signals drainage, insulation or ventilation to be corrected.
Autopilot, radar and communications
Radar, AIS, GNSS, eco-scandaglio, autopilot and VHF must be configured on the real profile, not left with generic settings. Offset, alarms, targets, routes and depth data are verified with a known test. The antennas and cables are mapped to make each point visible.
A second display is not redundancy if you use the same sensor. The test safely loses a source and controls the passage to the alternative. DSC call, transmitted location and VHF audio are tested without generating false alarms.
Programmed maintenance and spare parts
The plan separates daily controls, engine hours, monthly, seasonal and alaggio. D11 and D13 require different quantities and spare parts; the definitive list comes from the installed freshmen. Fuel filters, impellers, belts, anodes, fluids and fuses form the initial equipment.
For each component there is a position, tool and procedure. A spare present but unreachable does not reduce the stop. Hours, alarms and interventions remain in a common register, so crew and assistance work on the same technical history.
Degraded maneuver and government test
The test in the dock includes back and forth, stop, close on the two sides and response with measured wind. Steering, maneuver propellers and controls of different positions must react progressively and consistently. Cameras and sensors help, but do not replace visuals, communications and preparation of peaks.
There is also a procedure with an indisputable engine, an excluded station or a missing government figure. The crew must know how to transfer the command, isolate the failure and maintain the direction. The essential instructions are also available without connectivity or access to a remote portal.
Fire and Sentry Plant
Detectors, central, extinguishers, fixed system of the machine room and remote arrests must correspond to the diagram of the specimen. Each zone is identified and alarms are tested by controlled method. Fuel valves, fans and shutters must be able to be isolated from the planned location without entering the affected room.
Sentry pumps are tested automatically and manually, checking intervention levels, non-return valves and alarms. Sentry must remain clean after testing at sea: water, oil or refrigerant require a documented cause, not a simple cleaning before delivery.
Documentation and training of the shipowner
Manuals, schematics, freshmen, certificates and maintenance intervals are delivered in a consultable structure. The training includes ignition, shutdown, source transfer, alarm management and insulation of the main circuits. Verbal explanations do not replace written procedures.
At the end, a practical test is performed with the shipowner or commander: locate a valve, switch to an alternative source, read an alarm and restore a system. Any gaps are closed before acceptance and recorded in the minutes.
delivery controls
In the port we try utilities, protections, drains and alarms. At sea there are curves, temperatures, maneuver, noise and trim. On return, losses and loosening are sought.
Each relief is responsible, expiry and evidence. The test is repeated after the correction and remains in the technical file.
Consistent configuration
The Siren 60 can favour efficiency with D11 or performance margin with D13. The best choice depends on load and mission, not the highest number.
Engines, energy, layout, tenders and services must belong to the same operating project. Only so 19,45 meters become a reliable, measurable and maintainable platform.
