#MarineNotice - The Department of Transport, Tourism and Sport (DTTAS) wishes to advise that the master and navigating officers on any vessel fitted with electronic chart display and information systems (ECDIS) or an electronic chart system must be appropriately trained.

This requirement still applies when the equipment is not being used as the primary means of navigation, in accordance with the provisions of the Standards of Training, Certification and Watchkeeping for Seafarers (STCW) Convention, Regulations I/14 & VIII/2. This is also required in accordance with the provisions of the International Safety Management (ISM) Code, part 6.

Further guidance on ECDIS training is provided in Marine Notice No 51 of 2011.

#MARINE NOTICE - The Department of Transport, Tourism and Sport (DTTAS) has issued a safety notice for all users of Electronic Chart Display and Information Systems (ECDIS).

Following an announcement by the International Maritime Organization (IMO) concerning potential display anomalies in some ECDIS systems, the International Hydrographic Organization (IHO) issued an 'ENC Data Presentation and Performance Check' in October 2011 to assist mariners and help determine the extent of the issues.

Reports from sea received by the IHO confirm that a number of manufacturers’ ECDIS fail to display some significant underwater features in the 'Standard' display mode.

As a result, these ECDIS must be operated in 'Full display' or 'All display' mode in order that all significant objects are visible to the mariner until a software upgrade is made available.

The notice also warns that earlier versions of the ECDIS manufactured by the Japan Radio Co (JRC) will not display some types of wreck and underwater obstructions (including stranded wrecks) in any display mode. These models of JRC ECDIS must be used in conjunction with paper charts, and affected mariners should contact JRC or their suppliers to arrange remedial action.

More details are included in Marine Notice No 23 of 2012, a PDF of which is available to read or download HERE.

The latest Marine Notice from the Department of Transport, Tourism and Sport details the training requirements for the use of Electronic Chart Display and Information Systems (ECDIS) as a primary means of navigation.
Mandatory carriage requirements for ECDIS will be phased in between 1 July 2012 and 1 July 2018 according to ship size and class. All shipowners, masters and deck officers of merchant and fishing vessels, yachtsmen, nautical colleges and other users are required to complete both generic and ship specific training for the use of ECDIS.
The notice outlines the following as meeting the requirements for generic training:
- A NARAS Operational course completed after 1 January 2005.
- An ECDIS programme based on the IMO Model ECDIS course (1.27) approved by the Irish Maritime Administration.
- An ECDIS programme based on the IMO Model ECDIS course (1.27) approved by the maritime administration of an EU Member State or by a country recognised by Ireland under STCW 78.
As far as ship-specific training, the following areas should be covered in training delivered by the ECDIS manufacturer (computer-based training packages are acceptable):
- familiarisation with available functions
- familiarisation with the menu structure
- display setup
- setting of safety values
- recognition of alarms and malfunction indicators and the actions to be taken
- route planning
- route monitoring
- changing over to backup systems
- loading charts and licenses
- updating of software
Further details are available in Marine Notice No 51 of 2011, available to read or download as a PDF HERE.

About the 29er Skiff Dinghy

The 29er is a one-design double-handed, single trapeze skiff for youth sailors.

There is an active class in Ireland, just one of the 38-countries from across all continents now racing the high-performance skiff.

The 29er is one of the latest dinghy classes to arrive in Ireland and has a 50/50 split between boys and girls.

The class like to describe the boat as "The most popular skiff for sailors who want to go fast!".

Derived from the Olympic class 49er class and designed by Julian Bethwaite the 29er was first produced in 1998.

Two sailors sail the 29er, one on trapeze.

The class is targeted at youth sailors aiming at sailing the larger 49er which is an Olympic class.


The 6.25-metre high rig features a fractional asymmetrical spinnaker; a self-tacking jib decreases the workload of the crew, making manoeuvres more efficient and freeing the crew to take the mainsheet upwind and on two-sail reaches.

The 15.00 m2 spinnaker rigging set-up challenges crews to be fit and coordinated, and manoeuvres in the boat require athleticism due to its lack of inherent stability and the high speed with which the fully battened mainsail and jib power up.

The 74kg weight hull is constructed of fibreglass-reinforced polyester in a foam sandwich layout.

The fully battened mainsail and jib are made from a transparent Mylar laminate with orange or red Dacron trimming, while the spinnaker is manufactured from ripstop Nylon.

The mast is in three parts - an aluminium bottom and middle section, with a polyester-fibreglass composite tip to increase mast bend and decrease both overall weights, and the capsizing moment a heavy mast tip can generate. Foils are aluminium or fibreglass.

About the ILCA/Laser Dinghy

The ILCA, formerly known as the Laser, is the most produced boat in the world, with 220,000 units built since 1971.

It's easy to see why the single-handed dinghy has won the title of the most widely distributed boat of all time.

The Laser is a one-design dinghy, the hulls being identical but three rigs that can be used according to the size and weight of the sailor.

The class is international, with sailors from 120 countries. The boat has also been an Olympic class since 1996, being both the men's and women's singlehanded dinghy.

Three rigs are recognised by the International Laser Class Association (ILCA):

  • ILCA 4: sail of 4.70m2
  • ILCA 6: sail of 5.76 m2
  • ILCA 7: sail of 7.06 m2

29er skiff technical specs

  • Hull weight 74kg (163lb)
  • LOA 4.45m (14.4ft)
  • Beam 1.77m (5ft 7in)
  • Crew 2 (single trapeze) 
  • Spinnaker area 15.00 m2 (181.2sq.ft)
  • Upwind sail area 12.5 m2 (142.0 sq.ft)
  • Mast length 6.25m (20.5ft)
