What are the differences between a PC system like LNSY and a chart plotter?
There are many advantages of a PC- based system, so many in fact that we have dedicated a separate page to the topic. Other useful points With a laptop you don’t need separate software for passage planning: you just take the boat laptop home and do it there, or use the same software (licensed to install on as many PCs as you like, but will only run on one at a time) on your home PC and then just take the dongle and the route data with you down to the boat. This will save the software costs alone, which in many cases could be over £100. You don’t need an AIS CPA repeater (costing hundreds of pounds) as the laptop screen is more than capable of displaying everything you need including a list of vessels and their CPAs alongside the normal charting information.
