HOW TO WEAR A LIFEJACKET

A popular U.S.-based cruise ship style
A popular European ferry style

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.

ISM CODE - AUDITING

Ships now operate under the International Management Code for Safe Operation of Ships and for Pollution Prevention (ISM Code).  Since this is a Post on Auditing NAUTICAL LOG, who is a Trained Auditor, will not go through the requirements as these can be found on the Internet and in your local nautical bookshop - you do have a bookshop hopefully as they are a dying breed.  There are two types of Audit an External Audit and an Internal Audit.

AN tSEIRBHIS CHABHLAIGH

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.
