#ShackletonShips - The Ross Sea announced as the World’s largest marine park in the Antarctic is where ice patrol survey ship HMS Endurance nearly sank in the south Atlantic in 2008. Since then the ship has remained laid up, however in recent months she was scrapped, writes Jehan Ashmore.

HMS Endurance (A171) a former Royal Navy vessel based in the polar seas was named in honour of Sir Ernest Shackleton’s original expedition sail and steam ship Endurance.

The three-masted barquentine, Endurance was crushed by pack ice and sunk more than a century ago in late 1915. The incident took place during the Imperial Trans-Antarctic expedition of 1914-1918 led by the Irish born polar explorer. A 15ft model of the ship is on display in the Athy Heritage Museum, Co. Kildare and more recently a statue of Shackleton was unveiled. 

The 1995 built HMS Endurance had a near floundering incident in December 2008 while off Chile. The 5,129 gross tonnage vessel suffered flooding of her engine room that nearly sank her, following an error during routine maintenance on a sea suction strainer.

The damage was so severe that HMS Endurance was transported by semi-submersible ship to the UK, firstly Dartmouth and then Portsmouth  Naval Base. It was deemed far too expensive to carry out repairs and she was sold for scrap in 2013, however since Afloat’s coverage almost three years ago, the towage of the vessel only took place in June when bound for breakers in Turkey.

She had been employed as a hydrographic and support vessel for British Antarctic Survey (BAS), which is responsible for the UK's national scientific activities in Antarctica. A £150m newbuild RRS Sir David Attenborough currently under construction will join her fleetmates as outlined below. 

HMS Endurance was originally built as MV Polar Circle for Norwegians in 1990, then chartered to the Royal Navy and purchased. The navy equipped the vessel with Lynx helicopters as BAS aircraft cannot reach certain locations in the vast polar expanse.

Currently, the Royal Navy’s presence in these polar waters and the South Atlantic is tasked to HMS Protector (A173). Likewise of her predecessor, she operates along with BAS ships.

They are the civilian-manned polar research vessels, RRS Ernest Shackleton and RRS James Clarke Ross. The naming of the ship honours that of the British explorer who in 1841 visited the area (Ross Sea) located in southern Antarctica.

#ShackletonShips – With attention focused on job losses at BAE Systems shipyards in Scotland and Portsmouth which is to cease shipbuilding in 2014, the Royal Navy base is also home to the former Antarctic ice patrol survey vessel, HMS Endurance, writes Jehan Ashmore.

As previously reported, the fate of HMS Endurance, which was named in honour of the 'original' Endurance which sank after trapped in ice during Sir Ernest Shackleton's Imperial Trans-Antarctic expedition of 1914-1918, and according to Ships Monthly is now likely to be scrapped.

HMS Endurance, albeit not built at Portsmouth's historic shipyard that notably launched King Henry VIII's Mary Rose (see new museum) more than 500 years ago, also suffered a serious incident having nearly foundered off Chile in 1991. She was towed to the UK but was never repaired.

As previously reported on Afloat.ie, there are two other vessels directly named in honouring the famed Irish-born polar explorer.

Firstly is the 1995 built RRS Sir Ernest Shackleton which was originally MV Polar Queen built for Rieber Shipping of Bergen.

Ships Monthly also reports that the Norwegian company recently sold sister MV Polar Protector (A173) to the UK Ministry of Defence for £51m as the current Royal Navy patrol and survey vessel for the South Atlantic and Antarctic.

The second vessel is the Dublin Port Company tug Shackleton named in 2010.

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)
