Cruising Tips - Visibility

by Sail Staff, Posted March 27, 2006
Signal Advantage (March 2006)If you have an on-the-water emergency during the day, keep in mind that a mirror is a very effective signaling device. If the weather is clear and there is sunlight, the reflection from a mirror can be seen up to 100 miles away. While it does need sun, a mirror doesn’t depend on batteries, satellites, or the electronic watchkeeping of a potential

Chartplotter Protocols

by Steve Henkind, Posted November 20, 2008
Chartplotters are powerful extensions of GPS technology and provide tremendous convenience, but they can get you into trouble if you’re not careful. While my focus is on vector-based plotters (digitized charts, which are the ones typically found on recreational sailboats), most of my observations also apply to raster-based (scanned charts) plotters.Scale change matters.

GPS has greatly simplified certain aspects of navigation; at the mere touch of a button, a boat’s position can be determined within about 30 feet. Despite the reliability of these devices, boats are still being damaged because of navigational errors. After several decades of both navigating and teaching navigation, I’ve suffered a few close calls of my own and can recommend some ways to use your

It was important to sail all night and make good time

Search Patterns for Sailors

It’s late at night and you’re sailing downwind in a moderate breeze. You hear a faint scream, quickly go up top to investigate and discover, to your horror, that no one is on deck. Apparently, your shipmate has fallen overboard. You hit the MOB function on the GPS, get the boat turned upwind and proceed to the approximate spot where your companion fell overboard. He is nowhere to be

Rescue 21

by Gordon West, Posted May 9, 2011
First the good news. Throughout most of the continental United States, calling the Coast Guard on your marine VHF radio now ties you into one of the most modern marine radio networks in use anywhere on Earth. As of November 2010, the 26 Sector Command Centers in the Coast Guard’s Rescue 21 radio network can monitor transmissions along nearly 37,000 miles of coastline.
