Never used in four years in the S. Pacific. I don't have a chartplotter. Don't care for a dedicated machine that costs more than a PC. I have a built in small footprint PC and a laptop.

At one time I had 100 pounds of charts on board and used them to circumnavigate. But I have not relied on paper charts for the last 5+ years.

Computer charts are different and require more due diligence. But I feel it is worth the trade-off. Even if it is blasphemy.
