PWC PWC Weather and Water Conditions 2

Question 1

What is the most reliable source of marine weather information for a PWC operator before heading out?

Accepted Answer

NOAA Weather Radio or a VHF marine radio forecast

Answer

NOAA Weather Radio and VHF channel 16/WX broadcasts provide real-time, location-specific marine forecasts updated multiple times daily.

Question 2

In weather and wave terminology, what does 'fetch' mean?

Accepted Answer

The horizontal distance over open water across which wind blows to generate waves

Answer

Fetch is the open-water distance over which wind acts; a longer fetch allows waves to build taller and more powerful, directly affecting PWC safety.

Question 3

What is the safest technique for a PWC operator to cross the wake of a large vessel?

Accepted Answer

At approximately a 90-degree angle at slow to moderate speed

Answer

Crossing a wake at a right angle at moderate speed gives the PWC the most stable path over each wave crest and reduces the risk of a sudden pitch or capsize.

Question 4

At what approximate water temperature does hypothermia become a serious and rapid threat to a person in the water?

Accepted Answer

At 60°F (15°C) or below

Answer

Water at 60°F (15°C) or below can cause incapacitating hypothermia in a matter of minutes, far faster than most people expect.

Question 5

What does a rapidly falling barometer reading indicate to a PWC operator?

Accepted Answer

An approaching storm system with worsening weather

Answer

A rapidly dropping barometer is a classic sign of an approaching low-pressure system, which brings wind, waves, and precipitation.
