...Safe Navigation in Fog...

The following is a safe boating message from the National Safe
Boating Council, reminding you that National Safe Boating Week is
May 20TH through May 26TH.

Chances are that when you are on the water, you will at least
occasionally encounter reduced visibility in fog, and you will need
to know how to navigate through it safely. Fog forms when air over a
warm water surface is transported over a colder water surface,
resulting in cooling and condensation. Fog is usually considered
dense if it reduces visibility to less than one mile. It can form
quickly and catch boaters off guard. Visibility can be reduced to a
few feet, disorienting boaters. Learning to navigate through fog (or
avoiding it) is critical to safe boating.

Recent recreational boating statistics indicate that 193 accident
occurred in poor visibility.  This resulted in 43 deaths and 137
injuries. Prior to going out on the water, you can check visibility
readings from the NERACOOS buoys at to
see if there is fog in the vicinity of the buoy.

If you encounter fog, navigate at a slower than normal speed.
Slowing down will help you avoid collisions.

Turn on all of your running lights, even in daytime.

Listen for sounds of other boats that may be near you, or for fog
horns and bells from nearby buoys.

VHF NOAA Weather Radio should broadcast important information
concerning the formation, movement or dissipation of the fog. Pay
close attention.

If your vessel has radar, it can be used to help you locate
dangers that may be around you.

Use GPS or a navigation chart to help obtain a fix on your location.
If you are unable to get your bearings, stay put until the fog lifts
but make sure you are in a safe location.

Be familiar with horn and bell sounds that should be produced to
warn others around you when in dense fog.

Have a compass available. Even if you don`t know where you are in
the fog, with a compass you can determine the direction you are
