Safety Alert 04-17

Whether at Work or at Play Remember it’s a Shared Waterway.
Know the Navigation Rules and enjoy your day!

This Safety Alert reminds all operators of power-driven, sail, and human propelled vessels of the importance of maintaining a sharp look-out while on a shared waterway and recommends that all recreational boaters carry a DSC-VHF marine radio in order to communicate with other vessels.

Recently a catamaran type passenger ferry collided with a group of kayakers on a busy metropolitan waterway. The incident occurred during late afternoon while the sun was low on the horizon with an angle of about 15 degrees and the ferry was heading westerly into the sun’s glare. The ferry had just begun its voyage and was operating at about 20 knots across the waterway while a group of kayakers was ahead of the ferry and heading south. The low angle of the sun created significant glare on the water, obstructing the ferry operator’s view of the kayakers who were within the reflected light. The kayakers did not have a DSC-VHF marine radio with them and they were unable to hail the ferry. The ferry subsequently collided with multiple kayaks resulting in two serious injuries.

It is critical that all mariners, including recreational boaters, have a good working knowledge of the Navigation Rules before venturing out into a shared waterway. Commercial and recreational vessel operators need to know their responsibilities including the Steering and Sailing Rules, Conduct of Vessels in Sight of One Another, and Conduct of Vessels in Restricted Visibility. They also need to recognize the nautical lights and shapes and understand the sound and light signals that may be encountered in order to take appropriate actions to prevent collisions.

It is also critical that recreational boaters are able to communicate with all other vessels. If unsure of another vessel’s intentions boaters need the ability to contact the other vessel on the radio in order to indicate their location and ask such questions as “Do you see me?” and “What are your intentions?”. For more information on navigation rules and maritime communications please visit the USCG Navigation Center Website.

Operators of marinas and rental facilities are encouraged to develop guidelines for safety briefings, required safety equipment and for outfitting guides and renters with maritime communication devices. For more information please visit

There are many safety topics important to paddlesport enthusiasts. Depending upon where you plan to paddle, the required skill sets may be minimal or they can be highly technical in nature. Persons new to paddlesports will benefit from taking a paddlesports safety course and the knowledge gained will increase their enjoyment on the water. An example of a free online course is located at Training is also available from the American Canoe Association (ACA) and United States Coast Guard Auxiliary.

The Coast Guard strongly recommends that all paddlesport enthusiasts participate in boating safety education as well as taking paddlecraft specific skills training. Additionally, the following best practices should be considered every time before going out on the water:

• Always wear a Coast Guard approved life jacket
• Make yourself be seen (bright / contrasting clothing)
• Carry a sound producing device such as a whistle
• Carry a DCS-VHF radio
• Know your paddling limits
• Know the area where you will be operating
• Avoid paddling in main channels of busy waterways when possible
• Dress appropriately for the water temperature and forecasted weather
• Don’t paddle alone
• Tell a friend where you are going and when you will return - file a float plan.
• If you plan to be out after dark, you will be required to exhibit an all-round light or have a flashlight readily available
• Don’t drink alcohol and operate a boat or paddlecraft

The free Coast Guard Mobile App includes many resources including a function to file a float plan.

For the love of god stop pushing the DSC radios! Come summer time it would be nice to not have to listen to the DSC equipped radios constantly going off becuase someone in their kayak accidentally hit the button not knowing what it really does.

Isn’t that how you buzz the bar at the marina for another round of drinks?


The only thing worse Fraq is OSV mates in Fourchon sending test messages on the GMDSS set to “all” instead of themselves.

I used to do that sometimes just to be a dick…

Also, you can always just close your radio log at the dock at shut down your GMDSS equipment.

I used to do that, until a vessel manager slammed my dick in the door over it. He couldn’t tell me why, but you weren’t allowed to due to “regulations”

I’ve heard conflicting views about closing the log and shutting down GMDSS equipment while in port. I’m under the impression its okay to close the log and shut down everything but the Imarsat terminal because it transmits our LRIT. If the GMDSS log is closed, would we need to keep a separate radio log transiting around port?

I’m not exactly sure if you need to reopen the log for moving around Fourchon or not. Technically the only thing you need to log is distress traffic and tests so there wouldn’t be anything you’d need to log while shifting berths.

When somebody tells me “regulations” I always ask for the citing. Either they show me or they give me the standard, “Because I am from the office, smarter than you, and I said so!”, explanation in some form or another.

At that point I walk away giggling.
