#coastalnotes - The Port of Milford Haven, south Wales has completed further improvements to its lock gates at Milford Marina. The works by the port authority have created a more flexible and faster access arrangement for the marina and its dock customers.

The natural waterway of Milford Haven in Pembrokeshire is where the port handles oil and gas and as such is widely recognised in the industry as the energy capital of the UK.

As for the marina, in 2014 an additional set of mitre gates, known as the Samson Gates, were installed at the site which provided quicker and more frequent access, as well as additional support, for the existing gates. In the 2018 programme of maintenance, alterations have been carried out on these gates resulting in a much smoother and more efficient operation.

Marina customers will remember one of the sets of mitre lock gates sustaining damage during the extreme weather conditions during Storm Ophelia. A major recovery system was immediately put in place to ensure minimal disruption to customers, with a temporary drive system installed. Since then, the Port has been working collaboratively with Royal Haskoning and Pressure Design - commissioning them to undertake a detailed study and to design a more modern and robust system.

The upgraded operating system has shortened the lock time to five minutes and enabled the lock gates to operate 24/7 with the tide. Also, both sets of gates now allow pedestrians to cross during most states of the tide; the only time the crossing isn’t available is during ‘freeflow’. This is operated by a traffic light system.

Melanie Durney, Marina and Docks Manager, commented: “We recognise the impact that this had on our customers, and are grateful for their patience. The damage we sustained from Storm Ophelia was unforeseen, but we have used this event to undertake further improvement works. We are proud to be able to offer a more flexible and extended locking programme, and improve the experience for our marina and dock customers.”

A section of the Royal canal on the inland waterways will be closed between 15 Nov 2010 until 1 Dec 2010 to facilitate works at the Blackwater Aqueduct near Enfield which is situated on the long level between locks 17 and 18.

In  Maynooth, due to the installation of new lock gates and bank repairs at the 14th Lock near Maynooth, the canal will be closed from 17th November 2010 to 31st January 2011, both dates inclusive. It will also be necessary on occasions to close the towpath for health and safety reasons.

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.
