#HowToSail - Next month Howth Yacht Club will host a two-day course on essential navigation and seamanship for cruising in coastal waters.

Run on Saturday 13 and Sunday 14 October, the course is touted as the ideal introduction to the essential knowledge required to plan and safely undertake short cruising passages in coastal waters.

The "concise yet highly informative" course is geared towards skippers and crew who are new to cruising, but is equally suitable for sailing yachts, motorboats, RIBs, divers and sea anglers.

The course will include:

  • Charts and chart work
  • Safety
  • Navigation buoys and lights
  • ‘Rules of the Road’
  • Tides
  • Weather
  • Passage planning and pilotage
  • Modern methods of electronic navigation

Presented by David Jerrard of Sea-Craft, the course runs from 9.30am to 5.30pm each day in HYC. The course fee is €120 which includes the full course pack and documentation.

The course is open to both club members and non-members so feel free to bring along a friend or colleague.

For more details and booking information, contact [email protected] or phone Sea-Craft at 01 286 3362 anytime.

The deck lights used by cruise ships have been identified as a potential navigation risk at sea at night, in the investigation of a complaint by a yacht Skipper following an encounter with a cruise vessel, writes Tom MacSweeney.

It was investigated by the CHIRP Maritime organisation, the British (UK) Confidential Reporting Programme for Maritime incidents. The aim of CHIRP is to contribute to the enhancement of maritime safety worldwide. It says that it provides “a totally independent confidential (not anonymous) reporting system for all individuals employed in the maritime industry. It provides a similar aviation system.

The yacht Skipper reported to CHRIP that it was difficult to distinguish navigation lights amongst other deck lights:

“I was under sail in a Southerly direction when I saw the lights of another vessel off my starboard bow.” Endeavouring to keep clear “the relative tracks didn’t seem, to make sense if I was seeing what I thought was a green starboard navigation light.”

The vessel was a cruise ship which crossed a mile ahead, going from East to West.

“I should therefore, have been able to see the port navigation light, but could not convince myself there was a red light amongst the multitude of other lights visible on the cruise liner.”

As the vessels were both a safe distance from each other, there was no harm, but the amount of coloured lights on cruise ships has been identified as an issue needing attention.

The yacht Skipper said: “The Collision Regulations specify the minimum visibility of navigation lights. However, the impact of other bright lights, obscuring the navigation lights, is not appreciated. Vessels should ensure that their navigation lights are bright enough to be seen against the background of all their other lights and avoid using coloured deck lights where this can cause confusion. Very bright deck working lights obscuring navigation lights are often an issue on fishing boats as well.”

The CHIRP investigation comment said: “The Maritime Advisory Board highlighted the importance of taking a series of compass bearings in order to determine whether a risk of collision exists Navigation light visibility, irrespective of other lighting, must comply with COL REGS.

“They queried why classification societies permit these designs where visibility is obscured. Technology exists whereby deck lighting may be adequately shaded – permitting safe movement on board, yet not obscuring regulatory lights. The quality of lights bulbs used is another possible consideration. Take LED for example – are approved suppliers holding the introduction of these back due to a lack of any requirement in COLREGS?”

#Offshore - Just in time for the release of Disney’s new seafaring adventure Moana comes this National Geographic profile of a team of sailors recreating the incredible navigations of Polynesian boats that inspired the animated film.

The crew of the Hōkūle‘a sail the ocean with nothing but the sun and the stars to guide them — even watches are banned.

And the Hawaiian team have been doing it since the mid 1970s, on a mission to prove their Polynesian ancestors were master navigators of the vast expanse of the Pacific.

They’ve since rekindled a long-lost seafaring tradition across the Polynesian islands, and have set their sights on completing an audacious 60,000-nautical-mile round-the-world voyage that they began in 2013, all on an open-deck double-hulled voyaging canoe.

#MarineNotice - Marine Notice No 4 of 2016 advises of the risks inherent in the use of unlicensed electronic navigation systems and cautions against their use.

Unlicensed software and electronic charts may contain errors, resulting in inaccuracies in displayed information and indicated vessel position. Such unlicensed software should not be used for navigation purposes.

Vessel operators are reminded of the requirement to carry suitable nautical instruments and adequate and up-to-date charts for their intended voyages. All equipment fitted in compliance with shipborne navigational equipment regulations should be type approved.

The installation and use of unlicensed navigational systems and software on-board commercial vessels may invalidate a vessel’s certification and may also lead to the cancelation of a vessel’s certificates.

If in doubt, vessel owners/operators should confirm with their suppliers that their software is up to date and licensed.

#deadcow – Round–the–World Yachtsman and Afloat.ie reader Pat Murphy says he enjoyed our story about the weekend rescue of a cow by the RNLI in Waterford. Unfortunately, Pat and his wife Olivia related a tale where they came across another cow in the same area (above) that was not so lucky. 'We came across him/her about six miles south of Hook Head while on passage from Waterford to Padstow in Cornwall on August Monday last in our yacht Aldebaran', Pat told Afloat.ie.

'I reported it to Rosslare Coastguard Radio as a navigational hazard. It was so bloated I think that to make contact with it could result in a not very nice shower!' he said.

#InlandWaters - Despite the threat of floods amid the current weather warning, the recent extended period of dry weather has meant that water levels in Ireland's navigable inland waterways are lower than normal for this time of year.

Where water levels fall below normal summer levels, Waterways Ireland says masters should be aware that their vessels may be at risk of grounding, particularly deep drafted vessels.

To reduce this risk, masters should navigate where possible on or near the centreline of the channel and also avoid short cutting in dog-legged channels and navigating too close to navigation markers.

Proceeding at a slow speed will also reduce 'squat' effect, ie where the vessel tends to sit lower in the water as a consequence of higher speed.

Low water levels will also impact on slipways, with reduced slipway length available under the water surface and the possibility of launching trailers dropping off the end of the concrete apron onto the river/lake bed and causing damage to trailer, outboard motor or boat.

More slipway surface will also be susceptible to weed growth requiring care while engaged in launching boats.

Very dry riverbanks are more susceptible to erosion from vessel wash. Waterways Ireland asks masters to ensure they adhere to the speed limits and maintain a reduced wash.

Where appropriate by maximising on the number of vessels in a lock the total volume of water moving downstream is decreased. This also reduces the volume of water used.

Waterways Ireland asks users to be patient and wait for other boaters to share the lock rather than using locks for single passages.

Masters are also requested to make sure lock cycles are used for vessels travelling each way. Each lock cycle should take boats both up and down stream. All sluice gates and paddles should be shut when leaving a lock.

In addition, masters are reminded not to leave taps running at watering points or service blocks in the interest of water conservation.

#Navigation - The United States' National Oceanic and Atmospheric Administration (NOAA) has announced that it will cease publication of paper nautical charts in six months' time, according to Sail magazine.

Since the first maps charting the US coastline were published in the 1860s, the NOAA's Office of Coast Survey has been producing accurate and highly detailed charts to help all kinds of mariners find safe passage through American waters, from fishing vessels to merchant ships to cruising yachts.

But with the majority of ocean-goers now relying on GPS and other modern technologies, the use of paper nautical charts was seen as falling by the wayside by the Federal Aviation Administration (FAA), which took over the production of US charts in 1999.

Yet while printed nautical charts may now become the preserve of specialised cartographers like Bobby Nash, who designed a special classic chart for the Volvo Ocean Race finale in Galway last year, the NOAA will still be providing its ocean maps by electronic means via data or high-res PDFs.

#Navigation - Marine navigation systems in yachting and shipping are 'primitive' compared to the standard in air travel, according to an electronics expert.

As Yachting Monthly reports, Martin Bransby of the UK's General Lighthouse Authorities said that "demands on marine navigation are only getting tighter, yet electronic systems at sea a primitive compared to those used in air travel. This needs to change."

Bransby made his comments following a trial to tackle the problem of rogue GPS jammers in the North Sea by the lighthouse authorities at Trinity House.

The new PNT (positioning, navigation and timing) method uses new technology to transmit critical data in the even of the loss or failure of GPS, which is vulnerable to interference from a variety of sources, both environmental and deliberate.

"The more dependent we become on electronic systems, the more resilient they must be," said Bransby. "Otherwise, we face a scenario where technology is actually reducing safety rather than enhancing it."

These new trials come after news that the Irish Coast Guard is collaborating on a new system of marine monitoring that will help detect drifting or rogue vessels in international waters before they become a problem for individual states - such as the 'ghost ship' MV Lyubov Orlova which as of last week was still adrift heading eastwards somewhere in the North Atlantic.
