Radar: a worthy investment

May 11 2012 in Navigation, Seamanship by Vincent Pica

No accident at sea will ever have the blame apportioned 100 to zero, and as a boater you are obligated to use all available means to maintain a proper lookout. This means if you have radar, you had better have it on. But who wants that extra responsibility? Well, we’ve all heard the expression, “Ignorance [...]

Making Mistakes, Continued

Nobel Laureate Daniel Kahneman says we have two mental systems that see the world very differently.  System 1 is our subconscious which continuously watches and listens, looking for interesting or threatening things, processing huge amounts of raw perception into manageable meaningful associations.  This intuitive system 1 then passes its executive summaries to system 2, the [...]

Reader Marshall Santos just posted this brain twister in the Three Sheets NW forums. Can you offer any advice before he heads out into the dangerous Columbia? I’m taking my 34-foot “trawler” from St. Helens Marina to its new home in downtown Portland. The rivers are swollen with an occasional tree trunk passing by. My planned route is the [...]

Dirty jobs on the water — how to clean a navigation aid

110822-G-ZQ587-Coast Guard Cutter Henry Blake

Ever wonder who gets the fun job of maintaining all those navigation cans and buoys that keep us boaters off the rocks. It’s the Coast Guard and it has to be one of the least fun — but most important — jobs they do. This video was shot and produced by Petty Officer 2nd Class Eric J. Chandlerc [...]

Grounding by GPS

Aug 18 2011 in Navigation by Bill Ray

Channel

Navigation in a narrow shallow channel highlights some limitations of the nifty electronics aboard our boats.  Don’t get me wrong, I love the latest gear and use the heck out of my GPS – but I maintain a healthy skepticism for what it says, constantly crosschecking, never depending on one input. The shallow spots are [...]

New GPS satellite launches

An illustration of the planet Earth surrounded by orbitting satellite tracks

A new addition was made last week to the orbiting constellation of Global Positioning System (GPS) satellites overhead that most boaters rely on for their navigation fixes: the Air Force successfully launched the second of its interim GPS IIF satellites on July 16th, and signals indicate that the satellite is in position and on track [...]
