Weather Awareness Flashcards

What is a key danger of operating a boat in fog?

Answer: Greatly reduced visibility making collisions more likely

Fog dramatically reduces visibility, making it difficult to see other vessels, hazards, or landmarks, significantly increasing collision risk.

When traveling in fog, what sound signal should a powerboat under way make at regular intervals?

Answer: One prolonged blast every 2 minutes

A powerboat under way in restricted visibility must sound one prolonged blast at intervals of not more than 2 minutes.

How does water temperature affect a boater's survival time if they fall overboard during a storm?

Answer: Colder water dramatically reduces survival time due to hypothermia

Cold water rapidly draws heat from the body, causing hypothermia and significantly reducing the time a person can survive in the water.

What does a red sky in the morning typically signal for boaters?

Answer: Stormy or unsettled weather may be approaching

The maritime saying 'red sky in morning, sailors take warning' reflects that morning red skies often indicate moisture and storms moving in.

Which type of weather system typically brings clearing skies and improving conditions after it passes?

Answer: Cold front

After a cold front passes, skies typically clear and conditions improve with cooler, drier air behind the front.

When planning a boating trip, how far in advance should you check the weather forecast?

Answer: Check several days before and again the morning of the trip

Checking weather several days ahead helps with planning, and checking again the morning of the trip ensures you have the most current, accurate forecast.

What is wind shear, and why is it dangerous to boaters?

Answer: A sudden change in wind speed or direction that can capsize a boat

Wind shear involves abrupt changes in wind speed or direction that can catch boaters off guard and potentially capsize or swamp a vessel.
