TechWorks Marine has scheduled the deployment of a wave buoy off the coast of Wicklow on Tuesday 8 December, weather allowing.

The buoy will be a yellow DB 500 and have a flashing light sequence of five flashes every 20 seconds, with a range of three nautical miles. The buoy will be marked with a St Andrew’s sross and radar reflector.

The wave buoy will be deployed at 53° 2' 35” N, -5° 41' 17” W by the the AMS Retriever (Callsign MEHI8) with an AIS system on board which has a provisional callsign of CWPW01.

If the deployment is delayed due to the weather, it will be carried out on the next viable tide and weather window. Once deployed, the wave buoy will remain on site for a minimum of six months.

Further details can be found in Marine Notice No 57 of 2020, a PDF of which is available to download below.

TechWorks Marine has deployed an operational Wave Buoy by Port of Cork in late 2016, to be deployed at Roche’s Point on the approach to Cork Harbour.

As the Wave climate in Ireland takes its toll on equipment, a large platform was recommended in order to survive the heavy weather, and maximise visibility of the data buoy to the shipping activity using the harbour on a daily basis.

Central to this development is the TechWorks Marine TMBB-Data Acquisition and Transmission system, the versatile and configurable monitoring platform is designed around it. The TMBB is a robust, reliable and scalable data acquisition system, which ensures the ongoing collection and transmission of quality assured data to enable clients to make informed decisions linked to their commercial activity. Already operational, data is being transmitted in real-time every 20 minutes to the Port of Cork Operations station. The inertial wave sensor used on the buoy is the SeaView Systems SVS-603. The Mobilis Jet9000 buoy Hull was selected as the most robust and reliable platform for such long term operational deployment.

The engineering team at TechWorks Marine carried out the full system integration and testing and extensive onsite training was provided, combined with detailed hardware and software documentation. The TechWorks Marine Data buoy can be easily upgraded in the future with additional Meteorological and Oceanographic sensors given the modular structure of the TMBB system.

Ms Charlotte O’Kelly, CEO of TechWorks Marine confirmed that the Wave buoy was deployed operationally in early December following initial on-site testing by TechWorks Marine. Ms O'Kelly said: ‘At present, the data buoy reports directly to the Port of Cork operations centre from where its data is used to ensure the safety of ships coming in and out of the Harbour.’

Port of Cork Harbour Master, Captain Paul O Regan commented on the wave buoy saying: ‘To date the wave data we have collected has been extremely useful with regards to our shipping operations. Safety is our first priority at the Port of Cork and this technology will assist us as we see larger vessels arriving into the port.’

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
