GB/T18822--2002/3SO11592:20015.1 For boats with internal engine, internal engine-driven or internal engine water jet driven, the maximum power of the engine installed or the rated power of the engine as specified by the manufacturer shall be used for reverse test: For boats with external engine drive, the rated external engine power specified on the nameplate shall be used for the test.
5.2 For boats with internal engine drive or internal engine-driven, the inverter shall be installed in accordance with the provisions of the manufacturer. For boats with external engine driven, the inverter shall be installed in accordance with the provisions of the manufacturer. At the oxygen adjustment position in accordance with 5.7, the maximum speed (r/min) recommended by the engine manufacturer shall be provided.3 At the start of each test, the permanently installed standard fuel tank shall not be loaded more than half of its capacity. If a portable fuel tank is used for an outboard engine (a fuel tank for an outboard engine), at the start of each test, the portable fuel tank shall be placed between full and half load in the position specified by the manufacturer. If not specified by the manufacturer, it shall be located as far as possible aft. 5.4 The outboard shall be equipped with a fuel avoidance system supplied or recommended by the manufacturer and fixed in place, or with an outboard engine restraint device intended for use. 4.1.2.
5.5 The outboard engine shall be installed in the lowest position on the engine mounting surface L, or, if specified in the boat owner's manual, in the position recommended by the boat manufacturer. 5.6 Avoid the bottom, the engine and the inlet shall be cleaned, 5.? For propulsion devices with high power, except for excessive heave (dig) or loss of direction due to water discharge from the propeller, the longitudinal angle of the outboard engine, the inboard engine, the outboard drive or the water jet pipe should be adjusted to maintain the normal speed of the full gate. The propulsion device with unadjustable power should be adjusted to the maximum trim (head-up) position to allow acceleration from displacement to planing speed, and meet these requirements. 6 Test conditions and determination of maximum speed
6.1 The test is to be carried out in water with a wind speed of less than 5m/s (10kn) and a wave strength of less than 0.2m. 6.2 The test is to be carried out with no other internal load on the boat except for the equipment provided in accordance with the standard. 5.3 The fuel and the pilot's weight should not exceed 90kg or be less than 70kg. 6.? The speed at maximum throttle should be verified by not less than two throttle maneuvers in both directions exceeding the actual measured distance, or by any other suitable and acceptable method of measuring the speed of the boat, with an accuracy within 2 km or 1 km (whichever is the greater) of the actual speed. 7 Maneuverability test procedures and criteria
7.1 The test should be carried out on the national test route shown in Appendix A. 7.2 With full throttle, the boat should sail along a straight line parallel to the AB mark and within 5 m of the mark at a uniform speed of m.
Note: The following familiarization test navigation can be carried out at any throttle and speed. For a boat of 7.3m30kn, the distance d from the start of the turn to the avoidance line should be 61.m. For a boat of 7.4m30kn, the distance from the start of the turn to the avoidance line should be 6L plus 2l for every 1kn above 30kn. See Table 1.

line, and even the average rate of the equipment inspection and approval shall be reduced by the equipment inspection and approval department. The test shall be carried out under a service temperature of 10% per day. The test shall be carried out under a service temperature of 8% per day. The test shall be carried out under a service temperature of 10 ... The position is determined by the test speed of the boat. iKAoNiKAca
7.6 Complete the turn without reducing the throttle, without crossing the avoidance line, and assuming a route parallel to the avoidance line. Complete 6 navigation tests, 3 of which are turns to the left and 3 to the right. 7.7 In order to pass this test, the boat must meet the requirements of 7.1 to 7.6, and the operator should feel that there is no loss of directional control or stability, and it is not difficult to maintain the power position.
7.7.1 If a given engine installation can reach the maximum maneuvering speed determined by the test (that is, it meets the requirements of 7.6 and 7.7, and does not cross the avoidance line) less than m·, the boat manufacturer shall reduce the power of the tested engine installation and the maximum propulsion rated power indicated on the capacity plate until the boat meets the requirements of Section 7. Chapter 7 - pass this maneuverability test. 7.7.2 If the vessel can maintain control and stability on a straight course but cannot meet the turning test requirements of 7.6 and 7.7, it may reduce the speed and achieve the turning requirement of 7.6 at the reduced speed according to the new departure point from the avoidance line specified in 7.4. If the maximum maneuvering speed that does not meet the test requirements is not less than 85 m/s or less than 1/.kn, this maximum power may be used as the rated power. 7.7.3 A speedometer should be installed as standard equipment, with an accuracy of within 5% of the maximum maneuvering speed determined in accordance with 7.7.2. 7.7.4 A permanent sign indicating the maximum maneuvering speed should be installed and clearly visible to the operator, with the content of the example listed in Figure 2 marked on it.
in kn When the speed is above 0.0000, the maneuverability is limited. Sudden turns may cause loss of control. Reduce the speed before making a sharp turn in either direction. Read the boat owner's manual. Make sure that the text is acceptable to the country, or mark the following figure. The maximum height of the text mark should be no less than 5mm.

Owner's manual
The owner's manual supplied with the boat in accordance with ISO 10240 shall include at least the following contents: ... the normal propulsion rated power, — kW: - Do not use an engine with a rated power greater than the power shown on the boat's capacity plate; ... Do not maneuver with the propulsion unit in negative trim (calculated downward) at high speed. It may tilt to the side. This may cause instability during the transition from displacement speed to planing speed, and when operating in choppy waters. Negative trim (not applicable to boats equipped with propulsion units with power adjustment) should be used. - Do not sail at maximum speed in crowded shipping lanes or in weather and water conditions with poor visibility, strong winds and rough seas. For courtesy and for the safety of yourself and others, reduce speed and maneuver, observe and comply with speed limits and make sure there is no wake zone. - Observe the right of way provided for in the Dirty Traffic Rules and required by the International Carbon Evasion Rules. If you need to avoid a collision, it is always necessary to keep enough distance to stop or maneuver. If applicable, use the alternative warning signs shown in 7.7.4. iKAoNiKAca-
