105.9 Rules of the Road Flashcards
Is a vessel that is trolling a Fishing Vessel or a Power Vessel?
It is a power vessel, since other than the act of fishing, trolling does not inhibit maneuverability, like the using nets, lines, etc.
Proper lookout means
CONTINUOUS scanning, using all senses but primarily direct sight and use of equipment
When doing a proper lookout, always remember to look….
astern of you. For boats and ships coming at you from behind also have rules.
A risk of collision exists when the compass or relative heading of a boat…
… does not change over time.
Head-on boats alter their course (how) and (to do what)?
alter to starboard to pass port-side to port-side
In a crossing situation, the boat __ ____ is the stand-on boat. Your boat is the ___ ___ boat.
on the starboard; give-way boat
Is there any difference between a power vessel over taking a sailboat or a sailboat overtaking a power vessel?
No. The boat being overtaken is the stand on boat; the over-taking boat is the give way boat.
A stand-on vessels primary responsibility is to maintain ____ and ____, yet still ultimately avoid ______.
speed and course; collision
A boat further into the wind from you is considered a _____ boat, and the opposite downwind boat is considered _____.
windward; leeward
If you are the Give Way vessel, you must either (3 things)
change speed, change course, stop
Actions take to avoid collision should be done ____ and _____.
early and substantially (to make clear to other boat)
When two sailboats have wind on their opposing sides,
the one on a starboard tack (wind coming over the starboard side) is the stand-on vessel; the one on a port tack (wind coming over their port side) is the give way. Starboard-side light is green, starboard-side WIND (NOT BOOM) is go.
When two sailboats both have wind coming from the same side…
Why?
the windward boat (the one closer to the wind’s source) is the give-way boat.
Why? Windward boat likely have better manueverability, and might even be blocking the wind of the other boat.
Nuance — In sailing’s Rules of Racing, the windward side of the boat is always the side…
…. opposite from where the boom is sitting. (Boom, though, may not always be on the true leeward side of the boat, due to preventers or other issues.
In a narrow channel, ___ boat of less than ___ meters, and sailboats of ___ size, must….
This takes precedent over…
ANY; 20; ANY
not impede the passage of vessels that can only navigate within the channel.
…. normal rules of the road
Rules re: Separation zones include (3 things)
- Shipping vessels must travel in the indicated direction on a chart
- Must stay out of the neutral zone
- When crossing a shipping zone, do so AQAP and at a right angle
Enumerate the hierarchy of rights from least rights to greatest (six of them)
- Seaplane (must keep clear of all)
- Power vessel
- Sailing vessel (not under power)
- Fishing vessel (but not trolling only)
- Vessel restricted in its ability to move
- Vessel not under command
Adjust speed in fog to align with (three things)…
- limits of visibility
- density of other traffic
- maneuverability of own boat
When you hear a fog horn ahead, be ready to
turn right to avoid a collision
Sailboats are under less of an imperative to reduce speed in fog because reducing speed also…
…decreases maneuverability
Fog signals generally indicate the
…type of vessel or landmark blowing its horn
Fog signals are always issue in
…two minute intervals unless
Fog signals are either _____ or _____, lasting respectively ____ and ____ seconds.
short; prolonged; 1 second; 4 to 6 seconds. (NOTE on cards here, may be referred to as dash and dot)

… frequently isnt at the mast head but part way up the mast
Arc of a masthead light
White light, covering 180 degrees beam to beam plus 22.5 degrees (half of 45 degrees on each side. So 225 degrees total (180+22.5+22.5)
Arc of Side lights
Red or green, 112 degrees from bow on each side = (90 + 22.5)
Arc of stern light
White light at stern with arc of 135 degrees total (90-22.5 on one side, plus 90-22.5 on other side, or said differently 180 - 45 = 135)
Towing vessel lights color and position
A towing vessel has a yellow light at the stern when towing
PLUS
two or three white masthead lights facing forward
Another name for an anchor light is…
an all-around light
Anchor light characteristics (location, color, arc)
At the mast head (go figure…), white, 360 degrees
When at anchor with anchor light on, turn ___…..
off all other running lights.
Lights on a power vessel UNDER 50 meters
Allowable for under 12 meters is…
single masthead light, side lights, stern light
under 12, the masthead and stern light can be combined into one all-around light, but side lights must be lit (otherwise will appear at anchor)
Power vessel towing
Normal masthead, sidelights, stern lights
PLUS
stern yellow light all-around
PLUS
second masthead light if tow is < 200 meters
or
third masthead light if tow is > 200 meters
