I work for One of the major cruise companies and we were full ECDIS. it took some getting used to, but saves a large amounts of time in the long run! Our company did ECDIS the right way, by buying the largest screens avalible. with a IBS the screen also doubled as the radar,dp, auto pilot ect…
after working on a FULL ECDIS ships its hard to go back to paper. but it is nice to see the big picture layed out on the chart table!
