#INLAND WATERWAYS - A new mobile app that guides visitors around the trails of Lough Derg has gone live, the Clare Champion reports.

More than 20 trails are included in the app, from walking to cycling, driving, cruising and canoeing.

The app - developed in partnership between Shannon Development and US firm EveryTrail - uses Google Maps and the GPS system in smartphones to pinpoint trails near the user's location.

Users can download route descriptions, images and notes, get directions to the starting point and follow the the pre-plotted course.

The Lough Derg Trails app is available for iPhone and Android devices.

The Clare Champion has more on the story HERE.

Dag Pike talks us through the fact the ubiquitous IPhone will do nearly anything that you ask it to and it even makes phone calls. Much of what it does is related to land-based applications but now the boundaries are becoming blurred and the IPhone can become a wonderful navigation device for use at sea.

I am sure that many of you have already discovered the virtues of the IPhone and the more I use it for navigation, the more I discover what it will do. The problem is to narrow down what you want the phone to do rather than being distracted by the wide variety of applications on offer that will run your life if you let them.

Certainly the IPhone is the most complete navigation tool ever invented. In one tiny unit, it offers communication, navigation charting and positioning, compass, tides and currents, AIS, and even a log book, all at the touch of a button. As far as I can work out, there are only two things missing from the navigation repertoire of the IPhone. One is radar, and there really is no way around that one, and the second is a depth sounder and the only way that you might get that information from the IPhone would be to tie it onto a piece of string and drop it overboard! Everything or at least nearly everything else you might need for navigation is contained in the one small portable package.

It sounds too good to be true and in some ways it is. Being a small portable package makes it vulnerable. You might drop it, you might loose it, you might have a flat battery, or it might just stop working, so you could be vulnerable if you put all your trust into this one unit. For many, there has been safety in the philosophy of having each navigation requirement contained in a separate unit, then if one fails then you still have the other to keep you going. I would be very nervous about putting all my navigation requirements into the one IPhone when I was out at sea but where the IPhone would perform very well would be as a back-up to the conventional navigation systems and it would still remain working if all your electrics failed.

Let's have a closer look at each navigation requirement that can be provided by the IPhone and this will give a better picture of what can and cannot be done with the IPhone.

Communications

You can make phone calls and send text messages and have Internet access using the IPhone wherever there is coverage for the provider that you are using. If you want to get sophisticated, then you need the 3G coverage and that tends to be less extensive, particularly out at sea. For normal phone coverage, you can be pretty certain of coverage up to 5 miles offshore and in many areas up to 10 miles but after that it can be a bit hit and miss. There will always be dead spots that the signal cannot reach, particularly along a rocky coastline where there are cliffs, but this can be a problem with marine VHF as well.

Whilst there are detailed maps showing the mobile phone coverage on land there are none for sea coverage so you can only learn what is available when you are out there. You should have a VHF radio on board as well as an IPhone so that you can hear distress messages and send out your own if you are in trouble but more and more these days boaters are using mobile phones to communicate for routine matters such as organising a berth in a marina and you certainly don't want to be thinking about using the VHF to book a table in a restaurant.

With the Navionics navigation package on your IPhone, I love the way that you can just tap on a port or marina and up will come the telephone number. One more tap on the screen and the phone is ringing.

GPS Reception

GPS is the key to position fixing and the IPhone has a built in receiver that should know where you are all the time. However, you will notice that your conventional chart plotter has its GPS antenna located outside the boat to ensure continuous reception. Your IPhone GPS will have its antenna inside the boat most of the time so you will need to check whether the GPS is working here. It may work under the windscreen and it should certainly work in an open boat or on the flybridge but GPS reception is certainly something to check out before you commit yourself to IPhone navigation. I use the Pocket GPS World App because this shows you the reliability of the position information being produced by the GPS and you should consider this vital information.

There are very cheap or free GPS Apps that you can download that will show your position, speed course etc, which you could use in conjunction with paper charts if you just want to simplify your IPhone navigation.

Navigation

There is no doubt in my mind that that the Navionics App is the best one both for route planning and for navigation itself. This system has rave reviews and it works extremely well by offering most of the facilities that are found on mainstream chart plotters on the small screen of the IPhone. There is virtually worldwide chart coverage and you simply download the App that is relevant to the area you plan to sail in. For instance you can get chart coverage of the whole of the UK and Northern Europe for the price of a couple of bottles of wine.

It is the compact size of the screen that can make things difficult but you soon get used to this. When you are plotting a route, you need to take extra care that the route you have chosen is free from dangers and this can only be done by expanding the scale and then carefully studying the route in detail. I found it too easy to set the waypoints out and then find that the chosen route passes over a rock or a shoal that does not show up too well on the small screen or the scale that you are using.

You set the waypoints by selecting WP and then simply tapping the screen and with big fingers, it is not easy to set them accurately. However, they are easy to adjust, again by simply touching the way point and dragging it to where you want it to be. It took me 5 minutes to plot a route involving 10 waypoints and that including checking it out afterwards.

Once plotted all you need to do is keep the 'own ship' icon on the course line to follow the route. You can set the track plotting mode so that you have a record of where you have been and you get a heading vector and a speed read-out provided that you are doing more than 5 knots. That might be a handicap for sail boats because that heading vector is particularly useful to see where you are going in relation to the plotted route.

Don't take for granted that the GPS plot is giving accurate information. As mentioned above, I like to get a check on the quality of the GPS fix because when I was testing the IPhone, there were a couple of times when it plotted over the land and I was confident that I was on the water.

The Navionics App also has tidal and current information for 7 days ahead for a variety of locations around your position. There is so much information built into the system that you have virtually everything at your fingertips. However, there are some things that it will not do such as showing you the total distance of a route you have plotted and the courses and distances of each leg of the route. That said, the Navionics App has to be one of the most useful for those who want to navigate on the water.

AIS

You cannot get a direct read-out from the AIS transmitters around you because you need VHF for that but the next best thing is the Ship Finder App. With this App you can go to nearly any location around the world and it will show you the ships and boats that are transmitting their AIS signals. Tap on any one of the ship icons and it will show you all the details of the ship including its size, destination and course and speed. This function is more of interest than a serious navigation tool but it could be useful to indentify a ship out at sea and to give some idea of where it might be heading.

Compass

The IPhone has a built-in compass but there are also a number of Apps available with alternative compass displays. The standard display shows both an analogue and a digital read-out of the heading and checking this out at sea, it seems to be reasonably accurate, say to within 5°. The reason it is hard to get better accuracy is that the heading shown is the way that the IPhone is pointing and it is hard to get this lined up exactly with the bow of the boat. It only wants a slight movement of the phone to change the heading by several degrees. However as an emergency compass it works and you have the choice of the readout in either true or magnetic headings.

Weather

If your IPhone is connected to the Internet then you can access all the web sites that offer weather information. However I use an App called Weather Pro that will give you detailed 7 day weather at any port you programme in. The forecast is given for every 3 hours and details thing like wind strength and direction as well as predicted wind gust speeds. However, you do need to be aware that these are basically land forecasts and the conditions at sea could vary a little.

Comments

Every time that I have used the IPhone for navigation I have been amazed at its capabilities. It gives you so much information in such a small package that you will wonder how you ever managed without it. This really is the problem because in time you will take everything the IPhone can do for granted and you will no longer check that it is giving good quality navigation information. The biggest worry is the quality of the GPS position information because much of the navigation depends on this. I used the App that tells you the quality of the GPS fix but that means switching over to this at frequent intervals. It would be much better to have an automatic system that throws up an alarm when the GPS position is poor. I am sure that will come with time.

I would be nervous if the IPhone was my only source of navigation information. It is easily dropped, it is not waterproof and the battery has only a limited life. Of course, you can mount it into a holder and you can keep the charger plugged in to overcome the battery life problem and you can get extra life batteries. Where the IPhone scores is that it makes a great back-up system that will cover most of your navigation needs. In this respect, it could replace the hand held GPS and the hand- held VHF to a certain extent but before you throw these items away, I would suggest that you get a lot of experience with IPhone navigation. Only then will it become the true navigation friend that this remarkable piece of equipment is.

A stricken vessel was located in trouble on Lough Erne using lat/long data from an iPhone. 

 

A 999 call from the Motor Cruiser ‘Wee Rascal’ on Lough Erne in the early hours of this morning called on all the investigative powers of Belfast Coastguard as the vessel wasn’t even close to its reported position.

The vessel was on passage from Kesh to Enniskillen in windy, wet conditions when it called 999 to ask for assistance. Despite an extensive search of the area around its reported position neither the Enniskillen RNLI Inshore Lifeboat nor Erne Coastguard Rescue Teams could find the vessel.

Because the vessel had no flares, flash lights or VHF Radio on board to show rescuers where it was, Belfast Coastguard resorted to mobile phone technology. A locator i-phone application finally gave rescuers the vital latitude and longitude they needed to locate the vessel

The vessel was finally located 25 miles away from its reported position, dangerously amongst the rocky shoreline off Eagle Point. It was carefully brought away from the rocks by the skill of the  Enniskillen RNLI Inshore Lifeboat crew and taken to the safety of Beleek marina.

Coastguard Watch Manager Steven Carson said:

“A combination of luck and technology saved these four people from imminent danger this morning. They had charts onboard but obviously no real idea of how to get to their destination or how to report their position in an emergency.

“Vital hours were wasted eliminating one possible location after another, time that we wouldn’t have had if the vessel had struck the rocks and sunk. I hope that this experience will help the crew to realise why navigation training is essential for all mariners, whether you’re on a Lough or the open sea.”

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
