At eOceanic we are passionate about boating and it is our mission to provide empowerment at sea along the English and Irish coasts, as there has never been before. We fulfil this mission by creating two sister products: The web site, eOceanic.com, and the eOceanic application system. eOceanic.com is the finest seagoing intelligence platform for England and Ireland and is available to all, for free, for the common good. The eOceanic application system is a comprehensive seagoing application that allows all of the site information, as well as charting and tidal data, to be downloaded and used offline entirely independent of the site. There is no need for a network connection anymore, you have everything you need in the palm of your hand, on your smartphone, tablet or PC, or a range of all combined so that you have ample backup capabilities. eOceanic was built from the ground up just to serve you, right where you are, in real-time and to be so effective and efficient that it is a joy to use. With eOceanic, you will find the best decisions afloat are simple to see as all the options and data points are right at the tips of your fingers. * One swipe for tides * One swipe and touch to discover all the havens around you * One swipe and touch to see all the routes and coastal cuts immediately available to you * One swipe and a few more touches if you need to look for something specific. Then its extensive resource search feature will show you where you can get exactly what you want around you. When you know what you want to do, the application’s name says it all, just touch the ‘Go’ button or an object or waypoint and you are aided on your way by the finest raster charts available. Raster charts that feature, for the first time, a single plane view of the British Isles, with seamless scaling and full ‘touch to zoom’ functionality. When you are on your way, the application will be working behind the scenes to help you have a positive, enjoyable and safe experience. By maintaining a list of outlying hazards, such as rocks, shoals, and shallows, it will make you aware as you approach any of these listed dangers. Likewise, if there is something that concerns you in your area that we have not listed yet, just let us know and we will be delighted to add it to eOceanic.com for the benefit of all and synchronised to your device. Even with the utmost care, it is fair to say even the best of us slip up from time to time, and should that happen you have the assurance of a Man-Over-Board (MOB) function sitting centrally on the chart screen all the time. Once touched it immediately switches to guiding you back to the event location and automatically logs the key data points required by the rescue services should you require their assistance. eOceanic's logging capability is not just for a MOB situation, it provides a comprehensive means of keeping track of progress and events aboard. And, should you have the benefit of a network connection and wish to share your progress with friends or family, you can share your real-time track and logs on a personal eOceanic.com map page. Alternatively, if you want to fix something, find a better way of doing things or just make life a bit more comfortable aboard, you have an immediate repository of ‘Experience’ to call upon to handle situations with inspiration and confidence. All of this is just the start.
