A unique new tidal guide assisting river users to circumnavigate the city’s waterways was launched yesterday at the River Lee Hotel. CORKUMNAVIGATION is a pocket-sized map published by Cork’s community boatyard, Meitheal Mara. The guide is aimed at helping locals and visitors alike discover the city from a new angle by kayak, canoe or rowing boat. See link below to purchase the guide.

According to Cathy Buchanan of Meitheal Mara, ''very few people know that you can actually row or paddle all around the city, and experience a very different and special side of Cork. As several of the bridges are particularly low and some weirs quite high, they can only be passed at certain tides. With the CORKUMNAVIGATION guide you can successfully navi­gate the city’s 29 bridges and eight weirs at vari­ous stages of the tide.''

Niamh Twomey, Cork City Council Heritage Officer, added ''The River Lee is one of the great unexploited spaces in Cork, offering a beautiful route around the historic city centre. This guide will give the growing number of river users the opportunity to experience the natural and built heritage of Cork from the River Lee. The guide also includes quirky historical facts contributed by the late Cían Ó Sé.''

Corkumnavigate Cork city's 29 bridges and eight weirs with this latest pocket guide.

Originating near Gougane Barra in the Shehy Mountains, the River Lee flows east towards Cork City where it splits into two channels, form­ing the city's central island. Medieval Cork was a network of small river channels, which over the centuries have been covered in to leave just the north and south channels open. The river derives its name from the Irish "Laoi", meaning torrent or flood.

CORKUMNAVIGATION is a Meitheal Mara project, sponsored by Cork City Council and the River Lee Hotel. Fieldwork for the project was conducted in 2010 by the Cork Centre for Architectural Education, UCC and CIT, and sponsored by the Heritage Council.

The CORKUMNAVIGATION guide is available from Meitheal Mara via Afloat's Marine Market. Click HERE

#coastguard – Belfast Coastguard are issuing a warning following the Met Office forecast for rain during the remainder of Sunday and for strong winds or gales on Monday. The Northern Ireland and Scottish Coastline is expected to get hit with strong winds and high tides to produce large over-topping waves and another tidal surge, with the east coast particularly at risk.

Belfast Coastguard Rescue Co-ordination Centre manager, Steven Carson, said:

"With one of the worst tidal surges in recent years, we would urge members of the public to take extra care along our coastline at this time. Please stay away from coastal paths, sea walls and cliff edges. These types of conditions, with choppy seas and large waves, are likely to be with us for a few days yet, so please don't take risks. If you do get into difficulty, or spot someone else in trouble, call 999 straight away and ask for the Coastguard."

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
