New Lifeboat for Shannon Estuary

Volunteers at Kilrush Royal National Lifeboat Institution (RNLI) station on the Shannon Estuary have received a new state-of-the-art lifeboat which enters service this month.

The Atlantic 85 RIB (Rigid Inflatable boat) is not only bigger and more powerful than Kilrush's existing craft but it also fitted with the latest Search and Rescue technology and instrumentation, equipping the service to continue saving lives into the next generation. Kilrush is one of only two stations in Ireland and the UK which will receive such an upgrade this year.

Following the construction of a new station in 1996, an Atlantic 21 B Class lifeboat was placed on temporary duty at the Kilrush station however it was replaced by a new Atlantic 75 lifeboat the following October. Fourteen years later, this vessel will now be replaced by the new Atlantic 85.

Kilrush Lifeboat Operations Manager John Lamb said, "This is a great vote of confidence in the crew here at Kilrush. It shows that we are doing what is being asked of us and that are being rewarded by being entrusted by this the latest in lifeboat technology and development"

The Atlantic class of lifeboats is named after Atlantic College, where the design was originally developed. Like previous RIBs, it has a manually operated self-righting mechanism, deploying an airbag mounted atop the A-frame arch. It is capable of being beached in an emergency without sustaining damage to engines or steering gear. The Atlantic 85 is fitted with radar and VHF direction finding equipment and can be operated safely in daylight in a force 6/7 and at night in a force 5/6 gale.

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 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
