COLREGs MUST KNOW

Boating hierarchy (the right of way) (rule 18)

NUC > RAM > VCD > Fishing > Sailing > Power

Narrow channel/fairways (rule 9)

keep to starboard side that is safe and practicable (during practical test, there are many boats on your starboard side, so keep a good safe distance while keeping starboard)

3 kinds of vessel should not impede the narrow channel/fairways. In short, they must give way despite of boating hierarchy.

1. Vessel < 20m 

2. sailing vessel 

3. vessel engaged in fishing   

Risk of collision - if no compass onboard use clock reference. 

If bearing or clock reference NO change, risk of collision exist!

If bearing or clock reference changes, risk of collision may still exist (eg the vessel is long)

Traffic separation scheme (rule 10)

Joining and leaving at small angle of the general direction. 

If crossing, cross as nearly to 90 deg as possible.

Keep clear of separation line as much as practical

Overtaking (rule 13)

Overtaking vessel should keep out of the way of the vessel being overtaken (behind keep out)

Sailing also have to keep out of the way when overtaking power vessel despite rule 18 

Head on (rule 14)

both vessels alter to starboard except power vessel meet non power vessel eg sailing vessel (rule 18) 

Crossing (rule 15)

vessel who has vessel on starboard side should keep clear (vessel on the starboard stand on)

Applies to 2 power driven. If the case is NOT head on (rule 14) and overtaking(rule 13) then must be crossing

if you see port light, then you are give way vessel (remember as see red light, you give way)

if you see starboard light, then you are stand on vessel (remember as see green light, you can continue)
