#MarineWildlife - New marine protections for Northern Ireland's waters could provide a further sanctuary for our smallest marine mammal, the harbour porpoise.

As the Belfast Telegraph reports, the proposed Marine Conservation Zone (MCZ) for the area between Belfast Lough and Carlingford Lough would join the Causeway Coast zone protected in 2012.

The news comes some months after the European Commission put pressure on Westminster to designate more protected areas for the smallest of Ireland's cetaceans, whose swimming grounds are being encroached by offshore wind farm development.

And the new proposals for Northern Irish waters also include protections for important seabird colonies as well as an area of seagrass that's vital to local biodiversity.

But the overall scale of the UK's MCZ plans, reduced from more than 100 proposed zones to a total of 50 over the past two years, has been criticised by conservation groups for betraying a 'lack of ambition'.

#MARINE WILDLIFE - Protection for harbour porpoise off the north coast of Northern Ireland has been assured by the creation of two new areas of marine protection, as BBC News reports.

The new Special Areas of Conservation off Co Antrim encompass the sea and seabed surrounding the Maidens in the North Channel off Larne - protecting reefs and grey seals - and spots adjacent to the Giant's Causeway and Portrush Skerries in the north of the county.

Both areas are also considered of great importance to harbour porpoises, and according to Environment Minister Alex Attwood, the designation "comfirms that their numbers are significant throughout the year".

He added: "I hope this encourages people to visit the area to get a glimpse of these beautiful animals."

Campaigners are hoping for further coastal protections to be guaranteed by the Marine Bill, which will be debated at Stormont ths Autumn.

As reported earlier this year on Afloat.ie, the Northern Ireland Marine Task Force brought togethter politicians, environmentalists, fishermen and wind farm developers to ensure the new bill will deliver for all sea users.

The Irish Whale and Dolphin Group (IWDG) has validated 175 sighting records for June 2011.
The most commonly recorded species were bottlenose dolphins, accounting for 28 per cent  of all sightings, followed by harbour porpoise (25%), minke whales (13.6%), common dolphins (9%) and basking sharks (5%).
Other sightings included Risso's dolphins, killer whales, fin whales, humpback whales (0.6%) and pilot whales.
Clearly, with basking shark sightings evaporating from a trickle to a drip, we can draw a close to the 2011 basking shark season.
"This is the second consecutive year that basking shark sightings have declined, with a 36 per cent drop in sightings on the same period in 2010," said IWDG sightings co-ordinator Pádraig Whooley.
The total numbers compare with 270 sightings in June 2010. "The 35 per cent drop in sightings reflects the vagaries of Irish summers," Whooley added.
He also noted that this year marks the first time that the biggest cluster of sightings was off the coast of Co Dublin.

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)
