What are the three basic rules of navigation? - CORRECT ANSWERS-1) Practice good
seamanship - take all necessary action to avoid collision, taking into account weather, vessel traffic, and
limits of other vessels.
2) Keep a proper lookout - using both sight and hearing, watch and listen for other vessels, radio
communications, navigational hazards, and others involved in water activities.
3) Maintain a safe speed - safe speed is the speed that ensures you have ample time to avoid collision
and can stop within an appropriate distance. Safe speed will vary depending on conditions such as wind,
water conditions, navigational hazards, visibility, surrounding vessel traffic density, and the
maneuverability or your boat or PWC. Always reduce speed and navigate with extreme caution at night
and when visibility is restricted.
When should you take evasive action? - CORRECT ANSWERS-When approaching another
vessel whose intentions aren't clear
What is the stand-on vessel? - CORRECT ANSWERS-The vessel that must maintain its course
and speed unless it becomes apparent that the give-way vessel is not taking appropriate action.
- If you must take action, do not turn toward the give-way vessel or cross in front of it.
What is the give-way vessel? - CORRECT ANSWERS-The vessel that is required to take early
and substantial action to keep well away from other vessels by stopping, slowing down, or changing
course.
- Avoid crossing in front of other vessels
- Any change in course and/or speed should be large enough to be readily apparent to another vessel (A
series of small changes should be avoided).
When must you sound fog signals? - CORRECT ANSWERS-During periods of restricted
visibility, such as extreme fog.
, What must you do when you hear a fog signal? - CORRECT ANSWERS-If you hear the fog
signal of a vessel you cannot see, slow to a minimum speed until you are sure there is not a risk of
collision.
What is the fog signal for a power boat? - CORRECT ANSWERS-One prolonged blast at
intervals of not more than two minutes
What is the fog signal for a sail boat? - CORRECT ANSWERS-One prolonged blast plus two
short blasts at intervals of not more than two minutes
What is the pecking order? - CORRECT ANSWERS-1) Vessels not under command (NUC)
2) Vessels with a restricted ability to maneuver (RAM)
3) Vessels that are constrained by their draft (CBD)
4) Commercial fishing vessels
5) Sailboats under sail
6) Power boats or runabouts
7) Sea planes and paddlers
Sidelights - CORRECT ANSWERS-These red and green lights are called sidelights (or
combination lights) because they are visible to another vessel approaching from the SIDE or HEAD-ON.
- The RED light indicates a vessel's PORT (LEFT) SIDE
- The GREEN light indicates a vessel's STARBOARD (RIGHT) SIDE
Sternlight - CORRECT ANSWERS-This WHITE light is seen only from BEHIND or nearly behind
the vessel.
Masthead light - CORRECT ANSWERS-This white light shines forward and to both sides and is
required on all power-driven vessels. A masthead light must be displayed by all vessels when under
engine power.
- On power-driven vessels less than 39.4 feet in length, the masthead light and the sternlight may be
combined into an all-round white light
