The BRIG Navigator 700 is an off-production model that requires a different verification sequence than a new boat. The official 2020 manual distinguishes two configurations: monomotor and bimotor. They change powers, stems, permitted mass of the propulsive group, number of people and load limits. This guide organises documentary, plant and testing controls without attributing to the individual equipment seen only in the photographs.
Open the dossier with legacy status
The manufacturer's page marks the Navigator 700 as dismissed. In the dossier, the date of construction, the identification code, the target market, the version of the stern mirror, the original engines and subsequent modifications must be inserted. They attach certificate, manual, schematics, invoices, workshop reports and battery history. A consistent configuration is not the richest one, but the one that allows you to connect each component to a documented installation. The unavailability of a dedicated spare must be ascertained before signing.
Identify single or double before each calculation
The two versions share hull from 6,99 for 2,80 meters, height 2,08 meters, tubular from 0,58 meters and cockpit 5,05 for 1,59 meters. The distinction starts from the mirror: the single uses 25 inch stem, the double two 20 inch stems. You do not deduce the version by counting the engines present today, because an exemplary could have been transformed. Plate, certification and geometry of the attacks must agree.
sequence of control power and masses of the monomotor
The manual assigns to the recommended 200 hp single version, 225 hp maximum and 335 kg maximum per engine, controls and battery. Brand, model, serial, stated weight, mounting height and propeller are recorded. The legacy page mentions a maximum of 150 hp for the single: the divergence must remain in the minutes and must be resolved using the specific documents of the unit, not an average of values. The installed engine must also fall within the applicable insurance and administrative limits.
bimotor power and mass verification sequence
For double, the reference is 2 x 120 hp recommended and 2 x 135 hp maximum. Engines, controls and batteries can weigh up to 560 kg in total. The two thrusters are compatible for relationship, propellers, software and maintenance. Cablings and pipes must move without folds throughout the steering. The record notes regimes reached by both, temperature, pressure and charging, avoiding hiding a significant difference behind normal instrumental tolerance.
| Control | Single | Double |
|---|---|---|
| Recommended power | 200 hp | 2 x 120 hp |
| Maximum power | 225 hp | 2 x 135 hp |
| Mass propulsive group | 335 kg | 560 kg |
| Gambo length | 25 inches | 2 x 20 inches |
| Persons | 11; 12 only USA | 8 |
| L | 1.275 kg | 1.500 kg |
| Maximum total load | 1.225 kg | 1,000 kg |
| Maximum transport weight | 1.675 kg | 1.900 kg |
| Fuel tank | 340 l | 340 l |
People and label of the market of origin
The limit stated in the manual is eleven people on the monomotor, with twelve reserved to the US market, and eight on the double version. The page summarizes twelve without this distinction. The verification sequence takes pictures of the tag and registers market and configuration. In navigation, the numerical limit does not eliminate the obligation to distribute the weight, keep the commands free and assign sticks and places. An imported boat must retain consistent documents with the rules of the place where it is used.
Rebuild the weight balance
The empty structural mass is 700 kg and that equipped with consoles and seats, without motor and fuel, is 930 kg. The single motor has LCC of 1,275 kg; double 1,500 kg. The load displacement is 2,500 kg for both, but the maximum total load drops from 1.225 to 1,000 kg passing to double. Real weighing must include electronics, again, T-top, batteries, liquids and objects that often remain permanently in the gavones.
340 liters fuel system
The integrated tank has declared capacity of 340 liters. Bocchettone, cap, vent, filling tube, fishing, sensor and lines to the engines are controlled. The manual shows the general layout, while filtering and connections depend on the installation. Each tube must have suitable marking, correct fixing and distance from edges or wires. Persistent smells, stains or unexplained variations of the level require stop of testing and inspection, not simple ventilation of the compartment.
Batteries, battery and charging
The number of batteries varies between configurations and accessories. The control identifies capacity, technology, date, protection, fixing, ventilation and conductor section. The poles must be protected and the cables supported. The detachment occurs and voltage is measured at rest, during start and charge. In the double version, the architecture must avoid that a common fault makes both engines unavailable, within the limits of the installed scheme. Each change must be reported in an updated design.
Steering in the two configurations
On off engines, you will travel the entire wheel race by observing cylinders, pipes, connection bar and encumbrance. Loss, hardening or contact with cables and wells should not appear. In the double you control the parallelism of the motors and the clamping of the connections. In water, the response must be progressive at reduced speed before increasing the regime. An aesthetically centered steering wheel does not prove the correct adjustment; it counts the real position of the engines and the symmetry of the response.
Path and deck drains
The pump is tested by introducing a controlled amount of water and checking both automatic start and manual control. Flow, pipe and discharge are observed off board. Cover discharges must be free and function in the actual assembly of the boat. Sediments, loose bands and objects in the gavones can compromise both systems. After the test, the residual water is noted and the areas not visible with light and mirror or optical instrument are inspected.
Ventilation and fire prevention
The manual prohibits blocking ventilation of compartments containing tanks, batteries or fuel components. The extinguisher is not provided by the manufacturer: type, number, capacity and position are the responsibility of the owner with competent advice. You need to stay accessible and not locked. They control expiration, indicator, support and reporting. The supply takes place with engines and heat sources off; each abnormal smell is resolved before the start.
Installed console and electronics
Plotter, VHF, audio, compass and tools can be changed several times in the life of a legacy boat. The verification sequence does not assume that what appears in the images is serial. Each device is identified with power and protection, then tested in the available functions. Behind the console you are looking for unprotected joints, cables without support, open holes and interference with the rudder. The compass should be observed with accused and switched off to identify obvious deviations due to new installations.
Gavoni, sitting and fixing
Cover seats and modules must open without hindering the steps and without hiding components that require maintenance. Hinges, closures, bases, seals and traces of water are controlled. A heavy accessory added over blanket influence baricentro and balance of the masses. In the gavones it occurs that objects cannot hit pipes or wires. The file captures every blank compartment: these images make it easier to compare future changes and locate a leak.
Pressure and integrity of the tubular
Five independent rooms work at the nominal pressure of 0.15 bar. The test is performed with recorded temperature, because sun and cooling alter reading. Valves, joints, cones, parabords and areas close to the fixings are inspected. Previous repairs must be compatible with the actual tissue. Slow loss, detachment or deep abrasion require professional evaluation. The detergents used must be appropriate and petrol or solvents should not be used to remove stains.
Water testing with repeatable minutes
The test records people, fuel, equipment, sea, wind, engines, propellers and mounting height. It starts from manoeuvres to the minimum, reverse and stop; then they control planata, trim, turns and maximum regimen provided by the manufacturer of engines. It does not attribute a standard speed to the model, because the documentation examined does not establish it. In double compare the parameters of the two engines. Vibrations or ventilation should be diagnosed before modifying propellers or quotas.
Control of trailer and ground mass
The manual indicates maximum transportable mass of 1.675 kg per single and 1,900 kg per double. These numbers do not automatically include the cart and do not replace an overall weigh. Flows, axes, tires, brakes, winch, straps and supports of the hull, avoiding loads on the tubular. T-top and motors change height and swing. Before transfer, actual dimensions are measured and the road requirements applicable to the vehicle and route are checked.
final verification sequence before purchase
The minutes must close every ambiguity: single or double certificate, powers, weights, people, reservoir, tubular status, rudder, fuel, electric, bilge and fire equipment. Analyze abnormalities and estimates, not just a list of spuns. Since the Navigator 700 is out of production, there is also availability of spare parts for windscreen, seats, hardware and printed parts. The most important economic proof is to estimate the restoration needed to restore the specimen to the documented configuration.
Maintenance plan after transfer of ownership
The new owner should plan an independent baseline from the seller's statements. You replace the expired consumables, you control oils, impellers and filters according to the instructions of the engines, you clean the electrical connections and try the bilge. Tubular and hull are photographed with uniform light; pressure, tension and engine hours enter a register. After the first exits, check out locks, battery supports, fuel pipes and console and seats. The calendar distinguishes controls before each exit, monthly and seasonal. This base makes a future change recognizable and prevents a small anomaly to be confused with the normal age of the model.
Configuration assessment
The Navigator 700 offers a robust setting and a rare propulsive choice in the same platform, but the two versions are not interchangeable on the limit plane. The monomotor prefers load and number of people; the bimotor absorbs more mass and reduces the crew limit. A sensible purchase requires readable tag, consistent documents, accessible systems and registered testing. On a legacy boat, maintenance quality counts more than the amount of accessories added over time.
