#NAVAL VISITS – Two small University Royal Naval Units (URNU) patrol training boats of the Royal Navy are due to call to Cork city centre along South Customs House Quay this afternoon, writes Jehan Ashmore.

The pair are HMS Exploit (P167) and HMS Express (P163) and they belong to a 14-strong P2000 Archer Fast Inshore Patrol Class. They form the First Patrol Boat Squadron and their primary role is to support the URNU but they also contribute to a wide range of fleet tasking.

Each vessel displaces 54 tonnes and has a crew of five on a boat that is just over 20m and draws a draft nearing 2m. Top speed is 22 knots and they can cover a range of 550 nautical miles.

HMS Exploit is the Birmingham University Royal Navy Unit's Training Patrol vessel, although the unit covers a wide area, taking undergraduates from eight Universities in the region. She was built by Vosper Thornycroft and commissioned in 1988. The boat is berthed in Penarth Marina, near Cardiff.

Likewise HMS Express is based at Penarth, she too provides sea training and offers an insight into the modern Royal Navy for Wales URNU undergraduates drawn from Cardiff, Swansea and Glamorgan Universities and University of Wales Institute Cardiff. Last year she took part in the Three Peaks Challenge.

The patrol boats follow last month's call also to the city of the Marine Protection Vessel (MPV) Jura which at 84m long makes her the largest of the three-strong Marine Compliance Scotland fleet. On that occasion she docked opposite at the North Customs House Quay.

About the TP52 Racing Yacht

The TP52 racing yacht is a remarkable example of cutting-edge technology in the world of competitive yachting. Measuring 52 feet (15.85 metres) in length, this vessel is constructed entirely from carbon fibre, making it an incredibly light and agile craft.

The TP52 features a 6.25-metre high rig, complete with a fractional asymmetrical spinnaker and a self-tacking jib. This design reduces the workload of the crew, allowing for more efficient manoeuvres and freeing up the crew to focus on the mainsheet upwind and on two-sail reaches.

The spinnaker rigging set-up, measuring 15.00 m2, presents a challenge to even the most experienced crews, requiring them to be fit and perfectly coordinated. Maneuvering the boat requires athleticism due to the vessel's lack of inherent stability and the high speed generated by the fully battened mainsail and jib.

The TP52's hull is constructed of fibreglass-reinforced polyester in a foam sandwich layout, resulting in a weight of just 74kg. 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 made up of three parts, featuring an aluminium bottom and middle section, with a polyester-fibreglass composite tip to increase mast bend and decrease overall weight. The capsizing moment, which can be generated by a heavy mast tip, is also reduced through this design. The TP52's foils are constructed from either aluminium or fibreglass, depending on the specific requirements of the vessel.

Overall, the TP52 racing yacht is an exceptional example of the latest advancements in yacht design and technology. Its lightweight construction, advanced rigging, and high-speed capabilities make it a top contender in the world of competitive yachting, challenging even the most skilled and experienced crews.
