Carbon Monoxide the Silent Killer

Bob Cusack US Coast Guard Auxiliary

As more and more boaters use auxiliary generators to power the electrical needs of their boats, or small fossil fueled stoves to heat their boats now that fall is here, the incidents of carbon monoxide, “CO” poisoning have been increasing.  CO forms from the incomplete combustion of fuels such as gasoline and diesel.  On average about 10 to 12 percent of exhaust, gas is CO.   It is colorless, odorless and is a killer.  Your first defense against it is to outfit your boat with a carbon monoxide detector, which will set off an alarm when CO is detected.   A little over 650 parts per million can be toxic, so if you have an engine of any type running and you develop any of the following symptoms, a headache, dizziness and nausea consider that CO might be the cause.   At the first sign of these symptoms immediately, get into fresh air and shutoff the motor.  Continued exposure may be fatal.

What should you be on the lookout for?  While underway, the flag on the stern instead of flapping aft is actually flapping forward.   This is known as the station wagon affect as the forward motion of the boat and the superstructure cause the exhaust to be sucked over the transom and into the boat.  I know as it happened to us a few years ago during a flat calm as we motored off the coast of Maine.  Fortunately, we recognized the symptoms, ventilated the boat by opening as many ports as possible, lowered the dodger and stood up in the cockpit.  We kept everyone out of the cabin and in fresh air.  No more CO problems.

Among the other dangerous situations is what is known as teaking.  Done mostly by kids, it is being towed by or on something directly behind the boat and right in the exhaust stream.   Additional potential problems are having ventilators close to exhaust ports, having generator exhaust ports under swim platforms, and enclosing your boat if it is not designed to be enclosed.  A survey of your boat to identify where the exhaust ports are in relation to openings where the CO could enter is critical to the safety of all aboard.   In the end recognizing the symptoms, shutting off the source of the CO and getting the affected person(s) into fresh air are what you should do.  Later you may be able to remedy the problem by altering your boat if alterations done by a professional will alleviate the problem.  Stay safe! 

• NOAA Chart Announcement

NOAA announces end of traditional paper nautical charts

NOAA-certified Print-on-Demand partners will continue to sell up-to-date paper nautical charts
NOAA’s Office of Coast Survey, which creates and maintains the nation’s suite of a thousand nautical charts of U.S. coastal waters, today announced major changes ahead for mariners and others who use nautical charts. Starting April 13, 2014, the federal government will no longer print traditional lithographic (paper) nautical charts.

“Like most other mariners, I grew up on NOAA lithographic charts, and have used them for years,” said Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “We know that changing chart formats and availability will be a difficult change for some mariners who love their traditional paper charts.”

Since 1862, those lithographic nautical charts -- available in marine shops and other stores -- have been printed by the U.S. government and sold to the public by commercial vendors. The decision to stop production is based on several factors: the declining use of lithographic charts, the increasing use of digital and electronic charts, and federal budget realities.
“With the end of traditional paper charts, our primary concern continues to be making sure that boaters, fishing vessels, and commercial mariners have access to the most accurate, up-to-date nautical chart in a format that works well for them, ” explained Capt. Shep Smith, chief of Coast Survey’s Marine Chart Division. “Fortunately, advancements in computing and mobile technologies give us many more options than was possible years ago.”

NOAA will continue to create and maintain other forms of nautical charts, including the increasingly popular Print on Demand (POD) charts, updated paper charts available from NOAA-certified printers. NOAA electronic navigational charts (NOAA ENC®) and raster navigational charts (NOAA RNC®), used in a variety of electronic charting systems, are also updated weekly and are available for free download from the Coast Survey website. NOAA announced a new product as well: full-scale PDF (Portable Digital Format) nautical charts, available for free download on a trial basis.

The world of navigation is benefitting from advances in technology, Smith explained. He said that NOAA will consult with chart users and private businesses about the future of U.S. navigation, especially exploring the use of NOAA charts as the basis for new products.
“Customers frequently ask us for special printed features, such as waterproof charts, special papers, or chart books containing additional information,” he explained. “We are investigating new opportunities for companies to fill these market niches, using the most up-to-date information directly from NOAA.”

NOAA’s Office of Coast Survey is the nation’s nautical chartmaker. Originally formed by President Thomas Jefferson in 1807, Coast Survey updates charts, surveys the coastal seafloor, responds to maritime emergencies, and searches for underwater obstructions that pose a danger to navigation.

• MMSI Important Update

Maritime Mobile Service Identity (MMSI) Entry Required for DSC Radios to Function

If you are shopping for a new DSC (Digital Selective Calling) radio for your vessel, be forewarned that it will not transmit any DSC call until you obtain and install your nine-digit MMSI (Maritime Mobile Service Identity). The radio's user manual *must* be carefully followed during installation, and great care must be taken when inputting the MMSI, as mistakes are not easily corrected, if at all. Once the MMSI is stored, it should not be possible to alter it without contacting the manufacturer or possibly returning the equipment for a factory reset. Trying to save money by buying a DSC radio at a swap meet or flea market is obviously a bad idea. Purchasing a DSC radio from a reputable and knowledgeable dealer is the only way to be sure that the unit meets current requirements and will function as intended.

DSC radios are programmed to display the vessel's MMSI on start-up, so obtain your MMSI as soon as you purchase your radio. If the equipment is not configured with an MMSI, it will generate distracting auditory and visual alerts indefinitely and will not function properly. The manufacturers of DSC equipment are including these alerts to convince us to obtain and enter an MMSI so that this equipment can perform its intended lifesaving functions. A thorough tutorial on the installation and use of DSC radios is available at this BoatU.S. Foundation website <>, and a free registration process for obtaining an MMSI is available here <>.
