all you need to do is slow down to a "SAFE SPEED" and maintain a good "LOOKOUT"
a safe speed under the international rules of the road is....
(
and either recreational or professional all are bound to operate under regardless of size or speed of vessel)
Every vessel shall at all times proceed at a safe speed so that she can take proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and conditions.
In determining a safe speed the following factors shall be among those taken into account:
(a) By all vessels:
1. The state of visibility;
2. The traffic density including concentrations of fishing vessels or any other vessels;
3. The manageability of the vessel with special reference to stopping distance and turning ability in the prevailing conditions;
4. At night, the presence of background light such as from shore lights or from back scatter from her own lights;
5. The state of wind, sea and current, and the proximity of navigational hazards;
6. The draft in relation to the available depth of water.
(b)Additionally, by vessels with operational radar:
1. The characteristics, efficiency and limitations of the radar equipment;
2. Any constraints imposed by the radar range scale in use;
3. The effect on radar detection of the sea state, weather and other sources of interference;
4. The possibility that small vessels, ice and other floating objects may not be detected by radar at an adequate range;
5. The number, location and movement of vessels detected by radar;
6. The more exact assessment of the visibility that may be possible when radar is used to determine the range of vessels or other objects in the vicinity.
Lookout under the international rules of the road is....
(
and either recreational or professional all are bound to operate under regardless of size or speed of vessel)
Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision.
BUT accidents do happen because these rules are either not known or not followed.
Once an accident happens these mandatory rules will be investigated to see if followed....unfortunately it IS black and white no matter what you like, think, say or do .... its taught and followed all over the world.
