#chug – The Coal Harbour Users Group (CHUG) is a group that represents the interests of leisure users of the Dun Laoghaire Harbour & Boatyard, and also the interests of the public that use the resource. Consistent with this, CHUG wish to promote marine related leisure and sport activity for the "ordinary person" in the Dun Laoghaire area and in Dublin Bay. During April 2015, CHUG made a submission to the Dun Laoghaire Cruise Stakeholder Group relating to the proposed new ships berth within the harbour. Part of the submission suggested development of a Marine Leisure Centre in the area west of the West Pier, and suggested that some of the spoil that would result from proposed harbour dredging be used to reclaim and extend land there to accommodate the development.

Kevin Woods writes that CHUG members have viewed the DLR Draft County Development Plan 2016-2022. In the context of the plan, CHUG make the following comments and requests:

CHUG request that the area immediately west of the West Pier including the area known as "The Gut" be designated for marine pleasure, leisure, sport and education use. The development would principally include:
A public marine leisure centre operated along the lines of a municipal leisure centre. This is detailed below.
A new public slip suitable for use by small boats at all tides. There are few public slipways in the Dublin area, and of those, some are not usable at low tide. An additional slip would improve public accessibility to the water and to Dublin Bay in general.
Additional space for marine leisure use, including for storage and repair of small boats and equipment. This might be provided by land reclamation in the area shaded and marked (1) on the attached map.
While the above development appears to be in line with existing Draft Development Plan SLO 14 and SLO 95, these might be reviewed and revised as appropriate should this be necessary to carry out the above. This might be assisted by introduction a new SLO relating to the area marked (1) west of the West Pier along the lines of the following:
Objective to promote water related leisure, sport, education, training facilities for public use at the coastal fringe in the area know as The Gut to the west of the West Pier that may include the reclamation of land and also the development of a new breakwater projecting westward from the pier side. This proposal would be subject to a feasibility study, including an assessment of any options, access considerations and impact on adjoining users. The feasibility study would include appropriate environmental assessments including any required under the Habitats Directive in co-operation with the relevant agencies.

A Marine Activity Centre might include:
Club facilities - offices, store rooms.
Shared meeting room, training / education room, changing room / showers / WCs.
Drying room for wetsuits,
Diving equipment store room
Compressor room for filling diving cylinders.
Small boat repair workshop
Shelters for persons, equipment
Hardstanding for secure dinghy & rib parking, canoe / kayak, windsurf and paddle board storage, small craft trailer storage.
Car, coach / minibus parking.

The centre might also cater for:
Fishing, birdwatching, and nature related activity, and might be a base from which the following would be organised:
Training in water safety
Transition year and primary schools activities
Beach and marine nature, ecology, and environmental study activity.
Marine related art
Youth club facilities
A new scout den
A marine interpretive centre / marine history and heritage centre

#cruiselinerberth – Dun Laoghaire harbour as a leisure facility, is in danger of being damaged by the proposal of a cruise liner berth according to the Coal Harbour Users Group (CHUG) who have submitted a written response to Dun Laoghaire Harbour Company. The group says this is particularly so for dinghies and small craft, though this might be mitigated by development of alternative sailing area and facilities west of the harbour.  The group have asked if it might be feasible for a lifting bridge be included on the access causeway to the new cruise berth and could a municipal marine facility be provided as part of the plan.

CHUG says the Impact on larger leisure craft appears to be less significant and it would be in favour of the cruise berth development if it is likely to financially viable and bring in revenue to the harbour company and / or local authority.

The CHUG response to DLHC is below: 

Dear Sirs

Thank you for briefing the committee of Coal Harbour Users Group regarding the proposed cruise liner berth in Dun Laoghaire Harbour.

The proposed cruise berth is an enormous development that will project approx. 60% of the distance from the shore to the harbour entrance. The Harbour Company anticipate that the berth would be in use for approx. 100 visits per season – i.e. on at least every second day during the summer months. Other boat movements would be restricted while cruisers are moving / berthing in the harbour and manoeuvring outside the harbour. This berthing and manoeuvring is likely to be a slower and longer process than for the HSS.

The above is likely to represent an inconvenience for persons moored in the harbour or on the marina while entering and leaving the harbour, and while moving within the harbour. There may be occasions where a boat needs to urgently enter the harbour (e.g. emergency, weather conditions), and may be delayed by cruiser manoeuvring. Dinghy sailors are likely to be more severely impacted, particularly because sailing within the harbour will be restricted, and they may need to sail close to the harbour mouth while a strong south-westerly is blowing.

The disruption to small boat sailors might be mitigated by development of a Marine Leisure Centre and sailing area for dinghies and sailboards immediately west of the west pier. A marine activity centre might also provide activities and attractions for visitors on cruise liners. The idea of a marine activity centre is outlined later in this e-mail.

Items for consideration by the Stakeholder Group:
Might some of the gantries between the proposed cruise berth piles / fenders be lifted when not in use to allow dinghies to pass between them?
Might a lifting bridge be included on the access causeway to the new cruise berth?
Might land reclamation be carried out to facilitate the development of a marine activity centre? This might be achieved by use of spoil from dredging. The cost of pumping a proportion of this spoil across the west pier might represent a saving over the cost of its removal to the Burford Bank. The above would be subject to further investigation, EIA, and planning requirements. Based on anecdote, spoil dredged from the harbour may contain pollutants including toxic substances. The spoil from close to the harbour mouth and from outside the harbour may be less contaminated.

The suggested Marine Activity Centre would:
Be a municipal building operated on the lines of a local authority leisure centre, but incorporating facilities for clubs and organisations that would be available for a nominal cost.
Encourage, promote and enhance public access for the "ordinary man" (and youth) to the sea and to marine leisure and sporting activities. This would include persons that are not members of the yacht clubs and other existing (privileged) organisations around the harbour.
Provide a facility for delivering Water Safety Education (classroom / lecture room, practical work area)
Provide showers, changing rooms, offices for clubs and organisations, boat / windsurf / canoe storage yard.
Incorporate a new slipway for dinghies and shallow draft boats (there are very few public slipways in the Dublin area).
The sailing area would include a safety boom a few hundred metres offshore, and removal of rocks close to the shore (or marking of them).
Provision of a cantilevered pedestrian boardwalk along the harbour wall alongside the access road east of the DMYC, and widening of the access road. Development in the West Pier area has in the past been restricted by access road width. This may provide a solution to access issues.

Summary:

In our opinion, the harbour as a leisure facility, is in danger of being damaged by the proposal. This is particularly so for dinghies and small craft, though this might be mitigated by development of alternative sailing area and facilities west of the harbour. Impact on larger leisure craft appears to be less significant, and mainly represents an occasional inconvenience. In principle, CHUG would be in favour of the cruise berth development based on the information provided by the Stakeholder Group if it is likely to financially viable and bring in revenue to the harbour company and / or local authority.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
