There really is no future for C-Map
. It's a dead format mostly for reasons that have nothing to do with updates. It was easy to pirate the charts. Too easy. No one will invest in them . All the compaines that used to subscribe to the charts no longer do so. The current
trend is gfor larger companies to buy up smaller ones so they can remove them from the market place.
is the only internationally recognized electronic format for ships required to manitain charts - period. Nothing else counts. You can download new US chart updates on almost a daily basis as far as some chart somewhere is updated. They show up for work to do the job.
manufactures do not support the standard in all the new devices because they want to sell data too. They also want to be very sure you can't copy it and give it away to your friends. So you get a great deal on a new chart plotter til you find out the Navonics chips sell for $184 for the gold and $500 for thre platinum. A full set of new US paper charts for every place will probably set you back about $3,000. The ENC
charts just take a download. So in the overall virew the chartplotter
is worthless compared to the maps.
All charts are a little bit out of date and a little bit wrong. The navigator has to know that maps are never perfect. Naviagtion with imprecise data is a process of navigation
and piloting. It is about confirmation of as many things as possible until when noticed the chart is clearly in error. It may happen before you run a ground or not. It's the only way you can travel on the water
. You go around places a lot of the time because you don't trust the map.
C-Map charts can be purchased on eBay. Out of date charts are quite usefull. No one really can afford 100% up to date charts. Commercial
ships at sea are required under international law to maintain up to date charts - so they do. Recreational baots are not required to do so, but it is well advised that you spend money
for good charts.
would have acquired better charts if he could have. As it ws it did cost many lives and some chips.
