Weather & Water Conditions; Cloud Formations; Waves & Fog - Regal 3760 Owner's Manual

WEATHER & WATER CONDITIONS
Before a boating outing check the weather conditions. As
we all know the weather can change rapidly in many parts
of the country. It does so sometimes without being
predicted. NOAA weather radio reports are continuously
available on designated frequencies installed on VHF radios
and various handhelds. Also, many local radio stations carry
weather reports.

CLOUD FORMATIONS

Clouds indicate the type of current weather and upcoming
changes in the weather. Knowing the type of cloud
formations can assist you in choosing the appropriate
boating day or if already on the water will help you
understand any upcoming weather changes. Flat clouds
(stratus) normally indicate stable air. Cumulus clouds
indicate unstable air. Many times a "cottonball" or
cumulus cloud builds vertical height in the afternoon and
the result is a thunderstorm with increased winds and
waves; sometimes these storms are quite violent. You
can find additional information on weather (meteorology)
at your local library.

WAVES & FOG
As the wind blows across water waves
are created. The stronger the wind and
increased distance across the water
enlarges the wave action.
Other factors that can cause problem
situations for vessels are fog, currents,
and tidal changes.
Fog can develop inland on clear, calm
mornings. Coastal areas see large "blankets" of fog roll
in and stay for extended time periods causing sometimes
hazardous navigation conditions. If you are caught in the
fog, do not panic. Think of the best plan of action and
proceed carefully. If you are limited in navigation
equipment at the first sign of fog proceed to the nearest
shoreline and wait until the fog lifts.
Boats equipped with navigation equipment, local
waterway experience and charts should proceed to a safe
harbor. Use extreme caution, signal as needed, and reduce
to a speed where you can stop within half of your
forward vision range.
If foul weather catches you at sea do the following:
1. Slow down. Proceed with caution and put on your
life vests.
2. Try to reach the nearest safe shoreline.
3. Navigate your vessel slowly into the waves at a 45
degree angle.
4. Passengers should sit low in the center of the vessel.
