No, because the device may be discharged or broken from any impact, and nothing will happen to the card unless it gets wet or torn.
Despite the development of mobile applications in yachting, paper charts still exist. Professional navigator Mike Broughton explains why.
Why paper maps are still indispensable
#Nautical applications are actively used today to help navigate, explain the rules, and track the location of your vessel and everyone else using the Automatic Identification System (AIS). Weather forecasting apps are rapidly evolving to combine up to six complex weather patterns on a palm-sized device. These apps use satellite imagery, rain data, and even wind information from nearby observing stations.
Pros and cons of paper maps
Map apps have been around for over 12 years. Lower cost, size and weight, they are equivalent to hundreds of full-size maps. Electronic maps can be updated literally in seconds, while paper maps are manually updated and time-consuming. In the last century, during my service in the Royal Navy, the main task of the navigator on a warship was to update maps and almanacs.
Conservatives will point to notorious incidents in which the use of electronic charts led to a run aground, usually when the navigator was not close enough to see a danger, an island, or shallow water.
Finding a hazard on a paper map is much easier. This is due to the fact that you can move your eyes around the map very quickly. But for this it is necessary to always have at hand the maps of the largest scale, and this is not an easy task on a small yacht in a long passage. However, how will we only deal with ENCs if there is a complete power outage?
There is no doubt that electronics are more reliable these days, and typically at least half of the crew have separate e-map apps on their tablets and smartphones. In addition, these devices are becoming more and more waterproof. Having backup systems with independent energy sources # will help you cope with power outages.
However, responsible shipping presupposes the availability of paper maps of at least our navigation area. The Royal Ocean Racing Club insists on using paper maps only of the race area, while the organizers of the Rolex Sydney Hobart Race require competitors to carry 25 detailed maps that are physically counted during pre-race checks.
In practice, only a few modern navigators use paper maps in everyday competition. The ability to use racing navigation software with its high resolution gribs (weather and ocean currents digital files), yacht polar coordinates and routing algorithms is too powerful a solution to ignore.
The software helps keep track of your opponents and also easily identifies ships or people in need of assistance. It digitally records position, heading and speed, as well as many other parameters of the vessel every second. I have been using paper maps for many years to instruct the crew before a race. Even during short coastal races, the kart is an excellent visualization tool.
