What does it mean when you see another vessel's red and white lights but not its green light at night?
Answer: The vessel is crossing from your port side and you are the stand-on vessel
Seeing a red (port) light and masthead white but no green means the vessel is to your port side crossing your path, and you are the stand-on vessel.
What is 'freeboard' and why does it matter for safe operation?
Answer: The distance from the waterline to the top of the gunwale; lower freeboard means greater risk of swamping
Freeboard is the vertical distance between the waterline and the top of the hull; reduced freeboard from overloading increases the risk of waves washing aboard.
What is the safest approach when encountering a submerged object or shoaling water?
Answer: Trim the engine up, reduce speed, and proceed cautiously or turn back
Trimming the engine up reduces draft, while slow speed allows time to react and minimizes damage if you do contact bottom.
When anchoring, the recommended scope (ratio of anchor line to water depth) in normal conditions is:
Answer: 5:1 to 7:1 (line length five to seven times water depth)
A scope of 5:1 to 7:1 provides the correct angle for the anchor to set properly and hold; too little scope causes the anchor to drag.
A vessel underway in restricted visibility hears one prolonged blast every two minutes. What does this signal?
Answer: A power-driven vessel making way through the water
Rule 35 of the COLREGS specifies that a power-driven vessel making way in restricted visibility shall sound one prolonged blast at intervals of not more than two minutes.
What is the primary danger of operating a boat in 'planing trim' that is too bow-high?
Answer: Reduced visibility ahead and risk of a barrel roll in following seas
Excessive bow-up trim blocks the operator's forward vision and makes the boat unstable in following seas, risking a dangerous broach or capsize.
When fueling a gasoline-powered boat, what should you do immediately after fueling and before starting the engine?
Answer: Run the blower for at least four minutes and sniff the bilge for fuel vapors
Gasoline vapor is heavier than air and collects in the bilge; running the blower for at least four minutes expels these explosive vapors before ignition.
