#MarineWildlife - The RV Celtic Voyager departed the Port of Cork yesterday (Wednesday 24 October) for ‘Operation Orca’, a 12-day survey of an offshore killer whale community associated with the Northeast Atlantic mackerel fishery.

A team of marine scientists from University College Cork is on board the research vessel that’s headed to waters east of the Orkneys, to study the orcas that feed on mackerel between October and February each year.

“This is the first time a dedicated research vessel will be heading up to study these killer whales and we are hopeful to come back with a lot of data,” said PhD researcher and chief scientist Róisín Pinfield in her introductory blog for the survey.

“We will have cameras, GoPros, drones, underwater hydrophones collecting acoustic data so we can hear the killer whales and a RIB so we can get in close if weather conditions allow. Time to pray to the weather gods to keep the storms away!”

The Scientists@Sea blog will be regularly updated by the Celtic Voyager team once they reach the fishing grounds and begin their survey, which runs till Sunday 4 November.

The crew of sailors, artists, musicians and historians on board Ar Seachrán - who are retracing the famous voyage of St Brendan - were refused permission to land on Skellig Michael, it has emerged.
The Kerryman reports that though some visitors are understood to have landed on the island in recent weeks, the OPW refused the Brendan's Voyage crew on health and safety grounds.
A spokesperson for the OPW said it requires at least 10 days notice to make preparations for any visitors and repair damage to pathways and buildings occurring over the winter months.
Dr Breandán Ó Ciobhán of the voyage party described the news as "very disappointing".

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
