It's funny, I've heard from a couple of people the ENC is better but I personally like NavX better. I now have both and maybe it's cause I don't have the "best" charts for ENC.

I looked at Polar Navy and the info and the chart program didn't seem as intuitive. Like it was written for a PC and then ported over. When I get back to the states I'll take another look before we head thru the canal and into the Pacific.
