While some Afloat.ie readers plan to keep sailing through the colder months, and have surely taken note of UK Sails’ recent heavy weather sailing tips, most will have seen or will see their boats lifted out this month.

Either way, this is still an opportune time to maintain your vessel and ensure you’re still ready to sail once spring comes around — and Yachting Monthly has a guide to the essentials you should know for midwinter maintenance.

While modern boatbuilding has made for a hardier product, boat-owners should resist the temptation to simply lift and let live, as frost and cold can affect even the most durable boat.

Don’t put off the small jobs: get your rigging washed and dried, and mend those worn ends. Check your sails over for stitching and any spots of wear or chafing. And remove sensitive electronics like your chart plotter for safer storage at home.

Indeed, clear out your boat as much as you can to keep old and mildew to a minimum. If you’ve lifted out for the winter, be sure to remove all freezable liquids, too, on the off chance a leak leads to hull damage in sub-zero temperatures.

#MarineNotice - A recent Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) raises importance of maintenance as highlighted in the MCIB report into the scuttling of fishing vessel Jeanette Roberta in Glandore Harbour in late 2011.

As previously reported on Afloat.ie, the prawn boat was returning to port on 11 December 2011 when the skipper had difficulty switching the helm from auto-pilot to manual due to a known issue with "sticky solenoids". The boat subsequently veered off course without warning and was holed on rocks on Adam's Island.

The official report into the incident castigated the owner/skipper for continuing to sail the vessel with persistent navigation issues - and Marine Notice No 04 of 2013 reminds all fishing vessel operators to ensure that deficiencies with their vessels are rectified without delay.

It is the responsibility of the owner to ensure that a vessel is maintained and operated at all times in accordance with the requirements of the agreed Code of Practice. Owners of all vessels also have a legal obligation to operate their vessels in accordance with the law.

Meanwhile, the latest Marine Notice is directed at passenger vessel owners and operators - encouraging them to continue voluntary efforts to improve accessibility on their vessels.

A new questionnaire has been made available to inform the DTTAS about the extent of accessibility improvements introduced to maritime passenger transport services in the State.

Full details are included in Marine Notice No 05 of 2013, a PDF of which is available to read or download HERE.

#HOW TO - Sail Magazine have posted a valuable video guide demonstrating how to set a kedge anchor for your vessel.

Every boat should carry a minimum of two anchors to give you security should the wind shift or pick up overnight and cause the boat to sway.

The second anchor should always be a different design to the primary anchor - an aluminium Fortress anchor would be perfect for this, being light to carry should it be needed.

Choice of rope is also important for a kedge anchor, with nylon being the better bet for its strength despite its lightness.

#MCIB - The families of two fishermen found dead at sea off the Skerries last April may never uncover the circumstances that led to their demise. But the official report into the incident indicated that the absence of lifejackets was a significant contributing factor.

Ronan Browne (26) and David Gilsenan (41) were reported missing on the evening of 1 April after failing to return from a trip tending to lobster pots.

Their vessel, Lady Linda, was found the following morning upturned in an oil slick off Clogherhead with no sign of the crew.

It wasn't until a week later that their bodies were discovered caught in the vessel's fishing gear some five miles east of Clogherhead, as previously reported on Afloat.ie.

Post-mortem results found that both men died from drowning, with Gilsenan also showing signs of hypothermia.

With no eyewitnesses to the incident, the report by the Marine Casualty Investigation Board (MCIB) indicated a number of possible causes from eqiupment malfunction or shifting of lobster pots on deck, to the wave height and weather conditions on the day, which were reportedly deteriorating when the boat left port.

It also said that Browne and Gilsenan "were lifelong friends, both men were experienced and qualified marine engineers in the fishing vessel industry. Both men were experienced in boat handling and fishing and had worked together on many occasions."

But the report emphasised the lack of personal flotation devices (PFDs) on board, and noted that emergency equipment was stored under the deck and not easily accessible.

The MCIB's recommendations include a review of the code of practice for fishing vessels under 15m to establish "revised stability critera" and ensuring that all boats are fitted with automatic radio beacons that deploy upon capsize.

In a separate incident, lack of proper maintenance led to an unlicenced boat taking on water off Co Kerry last August.

The Claire Buoyant was carrying one crew, five passengers and 21 sheep from Beginish Island to Ventry when the vessel began to lose stability.

Skipper Eoin Firtear - who the MCIB described as having "limited sea-going experience" - and his five passengers were rescued by passenger ferry. All sheep were jettisoned overboard, with 18 eventually recovered.

The report reminded that the carriage of livestock should only be undertaken in appropriately certified vessels.

#TALL SHIPS - The flagship vessel for an Asgard-type sail training programme in Cork has been locked up in a boatyard since 2007, the Irish Examiner reports.

The Omar B was supposed to be the focus of a Youthreach project based in Bantry for early school leavers. But the schooner has spent the last four-plus years in storage in Baltimore, and has been deteriorating due to lack of maintenance - despite the scheme still notionally running, the newspaper report says.

Five two-man dinghies purchased with grant money have also reportedly spent most of 2011 in storage.

Co Cork's VEC has now put the €150,000 sailing programme under review following concerns over storage costs and lack of direction for the project.

The 75ft Omar B was donated to the CCVEC by owner and builder Don Attig in 2003 and refitted for use by students thanks to generous voluntary funding. Attig said the boat was of immense benefit to students who would not otherwise be in education.

Is your lifejacket safe? That's the question the RNLI is asking sailors this Sunday at Dun Laoghaire marina. And If last year's clinic's statistics is anything to go by then the answer is most likely no.

Over 90% of lifejackets tested at Ireland's two biggest sailing centres failed simple checks carried out by the Royal National Lifeboat Institute in 2010. From 91 jackets tested in Cork and Dublin, 83 failed a free inspection. More here.

lifejacketcheck

This year the Dun Laoghaire marina initiative with the RNLI aims to get more boat owners, sailors and crews to avail of the free test carried out at the clinic.

The Dun Laoghaire offshore lifeboat will be in the marina's Emergency Berth to allow you to get an close up inspection
and there will be RNLI personnel available to discuss any safety advice or search and rescue questions you may have.

 The RNLI will also be taking bookings for a free onboard visit to your boat by the local Sea Safety Officer.

Will your lifejacket work when you need it? Do you know how to make sure it's a correct fit? Do you know how to look after it? All these questions and more will be answered by trained RNLI Sea Safety advisors.

You can learn the importance of choosing, fitting and the maintenance of a lifejacket from 11am to 4pm in Dun Laoghaire at the Lifejacket Clinic with RNLI Sea Safety Team. Likely topics as follows:

Which one?
There are many different types of lifejackets and buoyancy aids on the market. We can help you decide which one is best suited to your needs.

What size?
Size matters! A lifejacket or buoyancy aid will only work properly if it is properly fitted. We can show you how to adjust the lifejacket to a proper fit and why crotch straps are an essential part of the kit.

Looking after it.
It is essential to look after the buoyancy aid or lifejacket properly. With proper maintenance and regular servicing, your lifejacket will last longer and you can ensure it remains reliable. At our lifejacket clinic you can find out what checks to carry out on your lifejacket and how to care for it.

When to wear it?
RNLI volunteer crew wear a properly fitting lifejacket with crotch straps whenever the go afloat on the lifeboat, no matter what the weather. The RNLI believes that lifejackets are useless unless worn. All too often, RNLI crews recover people from the water who were not wearing lifejackets, and have not survived. A lifejacket can buy you time for the rescue services to get to you.

Published in Marine Warning
With the lighter evenings now approaching and better weather on its way (hopefully!) many boaters will be thinking about getting back out on the water and sailing again. But have you carried out all of the maintenance needed to ensure that your boat is safe and seaworthy?

"Many of the water-based incidents that we deal with at this time of year involve engine breakdown as a result of lack of maintenance," says Garry Hall of the UK's Solent Coastguard. "People report running out of fuel, sometimes because fuel indicators are broken or because fuel can't get through pipes and the engine is starved. Electrical issues are also a frequent problem. Often oxidation happens if engines are laid open to the elements and it affects the wiring. Engines are susceptible to frost so following our cold winter they will certainly need a good service."

Ideally attend a Diesel engine maintenance course, see:
www.rya.org.uk/coursestraining/courses/specialist/Pages/Diesel.aspx

Whilst you're considering maintenance, don't forget to look at your lifejackets and make sure that they are functioning fully. Remove the cylinders and auto-mechanisms, washing them in fresh water. Now inflate the lifejackets using a hand pump, leaving them for 24 hours to make sure that they don't deflate. Then reassemble the lifejacket, ensuring that the cylinder is screwed back in securely. The RNLI have some good advice about how to maintain your lifejacket on their website. Go to www.rnli.org.uk/seasafety

Appropriate and fully functioning communications equipment will be vital should you find yourself in an emergency situation.  Have you got all the right equipment?

Check all your existing communication equipment.  Ensure your VHF DSC radio unit's MMSI registration is up to date with Ofcom so that the Coastguard has the right emergency contact details.  If you have an emergency position-indicating radio beacon (EPIRB) or a personal locator beacon (PLB),  replace batteries before they expire and don't just rely on the "test" button.  Also ensure the beacon's registration details are up to date so that the Coastguard has the right emergency contact details and correct information for both yourself and your vessel.

Aquaculture Information

Aquaculture is the farming of animals in the water and has been practised for centuries, with the monks farming fish in the middle ages. More recently the technology has progressed and the aquaculture sector is now producing in the region of 50 thousand tonnes annually and provides a valuable food product as well as much needed employment in many rural areas of Ireland.

A typical fish farm involves keeping fish in pens in the water column, caring for them and supplying them with food so they grow to market size. Or for shellfish, containing them in a specialised unit and allowing them to feed on natural plants and materials in the water column until they reach harvestable size. While farming fish has a lower carbon and water footprint to those of land animals, and a very efficient food fed to weight gain ratio compared to beef, pork or chicken, farming does require protein food sources and produces organic waste which is released into the surrounding waters. Finding sustainable food sources, and reducing the environmental impacts are key challenges facing the sector as it continues to grow.

Salmon is the most popular fish bought by Irish families. In Ireland, most of our salmon is farmed, and along with mussels and oysters, are the main farmed species in the country.

Aquaculture in Ireland

  • Fish and shellfish are farmed in 14 Irish coastal counties.
  • Irish SMEs and families grow salmon, oysters, mussels and other seafood
  • The sector is worth €150m at the farm gate – 80% in export earnings.
  • The industry sustains 1,833 direct jobs in remote rural areas – 80% in the west of Ireland
  • Every full-time job in aquaculture creates 2.27 other jobs locally (Teagasc 2015)
  • Ireland’s marine farms occupy 0.0004% of Ireland’s 17,500Km2 inshore area.
  • 83% of people in coastal areas support the development of fish farming
  • Aquaculture is a strong, sustainable and popular strategic asset for development and job creation (Foodwise 2025, National Strategic Plan, Seafood
  • Operational Programme 2020, FAO, European Commission, European Investment Bank, Harvesting Our Ocean Wealth, Silicon Republic, CEDRA)
    Ireland has led the world in organically certified farmed fish for over 30 years
  • Fish farm workers include people who have spent over two decades in the business to school-leavers intent on becoming third-generation farmers on their family sites.

Irish Aquaculture FAQs

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants, and involves cultivating freshwater and saltwater populations under controlled conditions- in contrast to commercial fishing, which is the harvesting of wild fish. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats. Particular kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture, both of which integrate fish farming and plant farming.

About 580 aquatic species are currently farmed all over the world, according to the UN Food and Agriculture Organisation (FAO), which says it is "practised by both some of the poorest farmers in developing countries and by multinational companies".

Increasing global demand for protein through seafood is driving increasing demand for aquaculture, particularly given the pressures on certain commercially caught wild stocks of fish. The FAO says that "eating fish is part of the cultural tradition of many people and in terms of health benefits, it has an excellent nutritional profile, and "is a good source of protein, fatty acids, vitamins, minerals and essential micronutrients".

Aquaculture now accounts for 50 per cent of the world's fish consumed for food, and is the fastest-growing good sector.

China provides over 60 per cent of the world's farmed fish. In Europe, Norway and Scotland are leading producers of finfish, principally farmed salmon.

For farmed salmon, the feed conversion ratio, which is the measurement of how much feed it takes to produce the protein, is 1.1, as in one pound of feed producing one pound of protein, compared to rates of between 2.2 and 10 for beef, pork and chicken. However, scientists have also pointed out that certain farmed fish and shrimp requiring higher levels of protein and calories in feed compared to chickens, pigs, and cattle.

Tilapia farming which originated in the Middle East and Africa has now become the most profitable business in most countries. Tilapia has become the second most popular seafood after crab, due to which its farming is flourishing. It has entered the list of best selling species like shrimp and salmon.

There are 278 aquaculture production units in Ireland, according to Bord Iascaigh Mhara (BIM) *, producing 38,000 tonnes of finfish and shellfish in 2019 and with a total value of €172 million

There are currently almost 2,000 people directly employed in Irish aquaculture in the Republic, according to BIM.

BIM figures for 2019 recorded farmed salmon at almost 12,000 tonnes, valued at €110 million; rock oysters reached 10,300 tonnes at a value of €44 million; rope mussels at 10,600 tonnes were valued at €7 million; seabed cultured mussels at 4,600 tonnes were valued at €7 million; "other" finfish reached 600 tonnes, valued at €2 million and "other" shellfish reached 300 tonnes, valued at €2 million

Irish aquaculture products are exported to Europe, US and Asia, with salmon exported to France, Germany, Belgium and the US. Oysters are exported to France, with developing sales to markets in Hong Kong and China. France is Ireland's largest export for mussels, while there have been increased sales in the domestic and British markets.

The value of the Irish farmed finfish sector fell by five per cent in volume and seven per cent in value in 2019, mainly due to a fall on salmon production, but this was partially offset by a seven per cent increased in farmed shellfish to a value of 60 million euro. Delays in issuing State licenses have hampered further growth of the sector, according to industry representatives.

Fish and shellfish farmers must be licensed, and must comply with regulations and inspections conducted by the Sea Fisheries Protection Authority and the Marine Institute. Food labelling is a function of the Food Safety Authority of Ireland. There is a long backlog of license approvals in the finfish sector, while the Department of Agriculture, Food and Marine says it is working to reduce the backlog in the shellfish sector.

The department says it is working through the backlog, but notes that an application for a marine finfish aquaculture licence must be accompanied by either an Environmental Impact Statement (EIS) or an Environmental Impact Assessment Report (EIAR). As of October 2020, over two-thirds of applications on hand had an EIS outstanding, it said.

The EU requires member states to have marine spatial plans by 2021, and Ireland has assigned responsibility to the Department of Housing, Planning and Local Government for the National Marine Planning Framework (NMPF). Legislation has been drawn up to underpin this, and to provide a "one stop shop" for marine planning, ranging from fish farms to offshore energy – as in Marine Planning and Development Management Bill. However, the Department of Agriculture, Food and Marine confirmed last year that it intends to retain responsibility for aquaculture and sea-fisheries related development – meaning fish and shellfish farmers won't be able to avail of the "one stop shop" for marine planning.

Fish and shellfish health is a challenge, with naturally occurring blooms, jellyfish and the risk of disease. There are also issues with a perception that the sector causes environmental problems.

The industry has been on a steep learning curve, particularly in finfish farming, since it was hailed as a new future for Irish coastal communities from the 1970s – with the State's Electricity Supply Board being an early pioneer, and tobacco company Carrolls also becoming involved for a time. Nutrient build up, which occurs when there is a high density of fish in one area, waste production and its impact on depleting oxygen in water, creating algal blooms and "dead zones", and farmers' use of antibiotics to prevent disease have all been concerns, and anglers have also been worried about the impact of escaped farmed salmon on wild fish populations. Sea lice from salmon farmers were also blamed for declines in sea trout and wild salmon in Irish estuaries and rivers.

BIM says over 95% of all salmon farmed in Ireland are certified organic. Organically grown salmon are only fed a diet of sustainable organic feed. They are also raised in more spacious pens than traditional farmed salmon. The need to site locations for fish farms further out to sea, using more robust cages for weather, has been recognised by regulatory agencies. There is a move towards land-based aquaculture in Norway to reduce impact on local ecosystems. The industry says that antibiotic use is declining, and it says that "safe and effective vaccinations have since been developed for farmed fish and are now widely used". Many countries are now adopting a more sustainable approach to removing sea lice from salmon, using feeder fish such as wrasse and lumpsucker fish. Ireland's first lumpsucker hatchery was opened in 2015.

Ireland's first lumpsucker hatchery was opened in 2015.

Yes, as it is considered to have better potential for controlling environmental impacts, but it is expensive. As of October 2020, the department was handling over 20 land-based aquaculture applications.

The Irish Farmers' Association has represented fish and shellfish farmers for many years, with its chief executive Richie Flynn, who died in 2018, tirelessly championing the sector. His successor, Teresa Morrissey, is an equally forceful advocate, having worked previously in the Marine Institute in providing regulatory advice on fish health matters, scientific research on emerging aquatic diseases and management of the National Reference Laboratory for crustacean diseases.

BIM provides training in the national vocational certificate in aquaculture at its National Fisheries College, Castletownbere, Co Cork. It also trains divers to work in the industry. The Institute of Technology Carlow has also developed a higher diploma in aqua business at its campus in Wexford, in collaboration with BIM and IFA Aquaculture, the representative association for fish and shellfish farming.
