What is the recommended HELP position when a boater falls overboard in cold water?
Answer: Curl into a ball with knees drawn to chest to reduce heat loss
The Heat Escape Lessening Position (HELP) involves drawing your knees to your chest to protect the core body areas and significantly slow heat loss.
What is the primary danger of operating a boat in fog?
Answer: Reduced visibility making collisions more likely
Fog severely reduces visibility, greatly increasing the risk of collisions with other vessels, fixed structures, and navigational hazards.
In fog, what sound signal should a motorboat under way sound at regular intervals?
Answer: One prolonged blast every two minutes
Under the Navigation Rules, a power-driven vessel under way in fog must sound one prolonged blast (4–6 seconds) at intervals of not more than two minutes.
What effect do strong offshore winds have on wave conditions compared to onshore winds of the same speed?
Answer: Offshore winds tend to create smaller waves close to shore but seas build farther out
Offshore winds blow away from shore and tend to flatten waves near the shoreline, but open-water seas can still build significantly at a distance.
What is a 'wind wave' fetch and why does it matter to boaters?
Answer: The distance over which wind blows across open water, determining wave height and strength
Fetch is the distance of open water over which wind blows; a longer fetch allows waves to build higher and with more energy, creating rougher conditions.
If a weather forecast mentions a 'gale warning,' what wind speeds are expected?
Answer: Winds of 34–47 knots
A gale warning indicates sustained winds of 34 to 47 knots, which produce very rough seas and are extremely dangerous for most recreational boats.
