Prevention of Collision at Sea

Editor's Note: This column is part of a partnership between Waterway Guide News and Commodore Vincent Pica, First District, Southern Region (D1SR) United States Coast Guard Auxiliary, who will be providing our readers with his valuable insights on a regular basis.

It has been over 14 years since we approached the “COLREGs” in a systematic way, from stem to stern.  This column (re)starts that.

Every boater has (hopefully) heard of the rule of “red, right, return” meaning to keep the red buoys on your right when returning from sea. What many don’t realize is that this old chestnut is one of many that represent the embedded knowledge of centuries of seafaring know formally as the “International Regulations for the Prevention of Collision at Sea” and the largely parallel United States Inland Rules.

Sometimes referred to by the old salts as the “COLREGS” or simply “The Rules,” it has been estimated that less than 10% of today’s boaters are familiar with them. And the IMO (International Maritime Organization, global governing body) estimates that 80% of all collisions at sea are due to “pilot error…”  So, this column begins anew a series of articles on The Rules that have one simple goal: Safety of Life at Sea.

Overview

First, back in the day, vessels were designated as “privileged” and “burdened.”  The privileged boat would hold her course and speed and the burdened boat would take “early and substantial” action to avoid the collision.  What the Coast Guard noticed through court cases though was that skippers involved in collisions would claim that they had “the right of way” or that they had “privileges.”  This implied something that doesn’t exist in The Rules – that you have no affirmative obligation to avoid a collision at sea, no matter how much “in the right” you are. 

So, The Rules were changed to remove this unintended subtlety.  Just about every reference to the term “right of way” was removed from The Rules and the terms “privileged” and “burdened” were changed to “stand-on” and “give-way,” respectively.

Their courses of action were retained – the stand-on vessel would hold her course and speed and the give-way vessel would take early and substantial action to avoid a collision – plus one caveat.  Under Rule 17(b), if the closing conditions between the two* vessels have deteriorated to the point that action by the give-way vessel solely can no longer avoid a collision at sea, the stand-on vessel is “required” to take the best action it can to avoid the collision.  Rule 2 also clearly states that a skipper “may make a departure from these Rules necessary to avoid immediate danger.”

Second, unlike in the U.S. Court system where everyone is innocent until proven guilty, all parties in front of an Admiralty Board or a Court of Inquiry is guilty.  The Board will simply apportion blame and it will never be 100-0.  So, even if a guy plows directly into you, see 17(b) above.

Third, there are only three conditions of vessels meeting on the waters – head-on, crossing or overtaking situations.  The Rules govern how the skippers are to interact with each other through helm control and sound, or radio, signals.

In that this column is the first in a series, I will give you some quick rules of thumb** now and come back to you with more in-depth information in the weeks ahead.

Rule 13 - Overtaking

Bottom line, if you are overtaking another vessel, you are the give-way vessel.  You cannot turn it into a stand-on crossing situation by speeding ahead and than cutting across the over-taken vessel’s starboard bow.

Rule 14 – Head On

If you see a boat steaming towards you in a head-on situation, “both” captains are required to turn to starboard (showing their red port-side light) and return to their respective compass headings once an appropriate passing lane has been established between them.  Under the Rules, they are “both” give-way vessels.

Rule 15 - Crossing

OK, I will use the term.  If another boat is crossing your bow from your right-hand (starboard) side, she has the “right of way.”  Turn to starboard and go behind her (called “going under her stern”).  If you can’t, stop your boat until she passes.

Here lies the body of Michael O’Day
Who died maintaining his Right of Way.
He was right, dead right, as he sailed along,
But he’s just as dead as if he’d been wrong.

More to follow in the weeks ahead.

BTW, if you are interested in being part of USCG Forces, email me at [email protected] or go directly to the D1SR Human Resources Department, which is in charge of new members matters, at http://join.cgaux.org/ or, for NY/CT/North NJ/western VT, go direct to DSO-HR and we will help you “get in this thing.”

* All the Rules apply to only those conditions where two boats, and two boats only, are involved.  When more than two boats are involved in a potential collision, “common sense must prevail.”

** The term “rule of thumb” came from days when a sailing captain would never draw closer to shore than the width of his thumb on the chart.

CAPTs all, thank you for engaging and thank you for taking safety of life at sea as seriously as it should be!  BZ, Vin

Verrry interesting.  It is really annoying when a professional captain takes advantage of COLREGS in a mean-spirited manner. Sailing eastbound on a starboard tack on Long Island Sound, I encountered as westbound motor vessel. I figured I was the 'stand on' vessel -- until I saw booms over each side of her, telling me she was a trawler actively engaged in fishing. Now I am the give way vessel. I hailed the fisherman on Channel 16 asking for a port-to-port passing. No reply. At a distance of 200 yards, the trawler hangs a left-hand turn.  I cannot turn upwind to avoid the fisherman and hundreds of feet of net. I had to turn to port to avoid collision. That turn resulted in a crash jibe which caused my port mizzen running backstay part at the top of the mast and the turnbuckle to be ripped out of the deck. I couldn't catch the name of the fisherman because I was too busy pulling my rigging out the water. What can one do?

RE: Commodores corner. An excellent statrt of the information which boaters need. Now, if we can just stop the PWCs from playing Kamakazi on my wake...

A while back, there was a great debate in one of the major magazines about overtaking a sailboat or goroup of them. Yes, I know what the navrules say; I am a licensed master. However, since they run at displacement speed, and powerboats have to throw a wake to overtake them, here is a modification of the rulles.As stated in Rule 26, radiotelephone act  (paraphrasing:): "...unless an agreement is reached by radiotelephone..."

What I do when running the ICW, especially in the spring and fall when large groups of boats are being marine snowbirds,  as I approach the group a quick call on 16 saying "group of sailboats near XYZ, if you all go to idle speed, I can overtake you without rocking you" Usually you hear a reply or the engines go to idle. My displacement speed does nit rock them. 

Another advantage is: If you sounded the PROPER whistle signal (boatspeak for horn), you would most likely get the one finger salute. (experience speaking here) because most bioaters don't know or follow navules, and voice is easier to understand your intentions.

I and colleagues find it odd STILL find it insane that any with enough money can buy and operate pretty much anything under 45’, go out rent a 25’ boat in South Florida! THANK GOD THE INSURANCE COMPANIES want newer owners to hire a captain in the beginning or at very least have us sign off on their” Competence” for larger vessels. 

It's crazzzzzy, your average ”Weekend Warrior” can't get his boat in and out of a boat ramp, but they can run all over the waterways Clueless. 

Year's ago a DJ had people pushing his boat off a sandbar why the engines are turning 3-6k that ended well. and if you use ”Sound Signals” for passing here on the weekends you get the ”NY” finger greeting. 

Would it be the end of the world if ”Weekend Warriors in Florida, where required ”License” Texas, has tons of lakes and require licenses. Why not Florida Where 95+% of boat owners run there Open Array Radar in the ICW (Yes I'm familiar with the USCG RULES on Radar, but seriously it's the ICW!)

I will skip the boat show occurrences

What an excellent re-intro to the COLREGS. The big-picture perspectives and the developmental history overview were very helpful. Plus, the observation that an Admiralty Board or Court of Inquiry will never find any party blameless was sobering. I really look forward to further articles like this -- authoritative, well-written, and most informative.

Thank you for the interesting article.  Always good to refresh our knowledge of the rules.  Have had a few interesting crossing situations with large commercial vessels, particularly when motor sailing at night.  Even though displaying a steaming light, some large vessels crossing from my starboard side assume I am under sail only and try to give way by turning to port, at the same time I am turning to my starboard under the premise I am the give way vessel.  Makes for a tense moment.  Learned necessity to hail on VHF to keep everyone on same page.
