BTR #11.

We have now come to the final Rule under Steering and Sailing Rules and it is so very important Rule 19 has its own Section III.  It covers the Conduct of Vessels in Restricted Visibility which are conditions that no sensible seafarer likes being at sea in.   The recreational boater who has paid attention to the local weather forecasts most likely would not be out on the water that day.

Rule 19:  There are five (5) points that direct seafarers how to behave in restricted visibility when they may know that the other vessels are there but of course cannot see them. 
Point (d) covers the use of radar and has two (2) sub-parts which direct course changes based ONLY on data obtained by radar.
Point (e) directs the navigator if it is determined risk of collision to exist.

Rule 19:   The information and direction given is the same as the International with the five (5) points and point (d) having two (2) sub-parts covering use of radar data.

This completes our coverage of the NAVIGATION RULES Steering and Sailing Rules in their three (3) Sections I, II, III.


Our tip today is to carefully study these Steering and Sailing Rules and refer to the illustrations online under the various States boating instruction websites.  If you have any questions or need clarification of these NAUTICAL LOG Posts contact me at

If you are out boating do not force your way even if the other boater is the give-way vessel.  He most likely is not as knowledgeable as you are after completing this Series and all your study!!

Good Watch.

Several times during the year NAUTICAL LOG has had visitors searching for lifejacket instructions. With two just over Christmas we decided to publish something for everybody to see and read.
Choose a Coast Guard approved life-jacket and make sure it is undamaged. Make sure life-jackets are readily accessible, never locked away. Check the fit, there are adult, child and infant sizes, the correct one MUST be used. Choose bright colour life-jackets so as to be seen easily by Search and Rescue (SAR).Put your life-jacket ON BEFORE you leave the berth. Make sure you have a light and whistle attached AND they BOTH WORK.

It sometimes happens that one is going to write a Post on a subject when lo and behold there is already an excellent one.  Such is the case today; so rather than repeat everything let me refer you to the source of that Post

At present we are experiencing Perigean Spring Tides which occur when the Moon is at perigee on its oval path that is the closest point to Earth.  One of the principal results are higher than usual Spring Tides as against the Neap Tides.

Should you be interested in the full explanation of this phenomenon then you might like to reference "Old Salt Blog" which has an excellent explanation of this event and uses all the correct terms - quite unlike our Media here in South Florida.

This month saw the commissioning into the Irish Naval Service of a new Class of Irish Naval vessel more of the Frigate size than the previously Corvette size.  However they are all classed as Patrol vessels, the new vessel is LÉ Samuel Beckett P61.NAUTICAL LOG wishes her well and a successful service.

The older vessels saw unbelievable service and value for money the first being commissioned in 1979 and continued through the '80's and 90's into the 21st. Century.  During those years in addition to patrolling the stormy seas around the rugged Irish coast they made passages across the Western Ocean to the United States and Canada, south to South America as far as Argentina, and east to Asia as far as Korea.  Such passages are really remarkable for such small vessels and show the competence of Irish seafarers who as Naval Officers and Merchant Marine Officers train together.
