#EnterDryDockVideo - Afloat.ie has been informed by the Department of Defence that sea-trials of Naval Service latest newbuild OPV90 James Joyce took place between 6-9 March with delivery due shortly, writes Jehan Ashmore.

As originally reported, the trials took place in the Bristol Channel which is accessed from the estuary to where her builder's yard, Babcock Marine & Technology is located in Appledore, Devon. 

After her delivery to the Naval Service, the €54m newbuild is to be commissioned in May. Likewise of her predecessor and delivery of the third and final newbuild in late 2016, the trio will feature drone technology and un-manned mini submarine capability. This will dramatically improve surveillance and incident response times.

As previously reported on Afloat.ie, the dry-docking of LÉ Samuel Beckett (P61) in Cork Dockyard last month was a pre-scheduled period and the date of entering the facility can now be revealed to have begun on 23 February.

According to the Naval Service the dry-docking was standard practice with new vessels to ensure all is well with hull fittings and the ship's capability.

The above video footage only recently published was taken from L.E. Samuel Beckett's bridge-mounted camera view that overlooks the bow of the leadship OPV90 class.

The scene shown is of the OPV departing off the Naval Base's harbour berth on Haubowline Island in lower Cork Harbour. From there she makes the short passage upriver to Cork Dockyard.

As the OPV90 heads closer to Cork Dockyard, Afloat.ie had previously reported of a blue-hulled Russian research vessel among other crafts berthed along the quayside. This vessel was the Geolog Dmitriy Nalivkin of 1,935 tonnes built in 1995 during the Soviet era at a yard in Turku, Finland.

Next we see the LÉ Samuel Beckett (P61) swing into the dry-dock, or graving dock which is 165.5m (539ft) long by 22.5m (73ft) wide and with an access width of 21.3m (70ft).

The dockyard was originally established by James Wheeler in 1853. Currently, Cork Dockyard, is a member of the Burke Shipping Group which is a subsidiary of the Doyle Group.

#OPVJamesJoyce –  L.É. Aoife (P22) is on her last patrol before decommissioning and direct replacement newbuild, James Joyce is scheduled to carry out sea acceptance trials in mid-February, writes Jehan Ashmore.

According to the Department of Defence, should the second OPV90 ‘Beckett’ class proceed with sea-trials as scheduled, the newest addition to the Naval Service should make her delivery voyage to Irish waters in March.

The Department added that the formal commissioning date for the £54m offshore patrol vessel will be arranged when the ship arrives in Ireland. She is 90m in length, with a top speed of 23 knots and will have a range of 6,000 nautical miles.

As Afloat.ie previously reported, her sister leadship, L.E. Beckett (P61) undertook sea trials in the Bristol Channel prior to her delivery voyage with a first arrival to Cork Harbour last April. 

James Joyce was floated-out in November from the shipbuilding hall of Babcock Marine & Technology. The yard is located on the banks of the River Torridge, Appledore in north Devon.

She is to be followed by a third sister in which no name has been chosen so far. This final OPV90 is to enter service in 2016.

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
