Short answer is "no".
I've used NT for a long time, but have becomei increasingly pissed at the company. One version, maybe 7.x, allowed use of the free ENC charts. However, they had some problems and had essentially a recall awhile back. They sent free upgrade discs to everybody to fix the problem, but the "upgrade" disabled the ability to use the free charts. The latest version will let you use the free charts again, but only if you buy a software package from them at "a nominal fee". The upgrades are more expensive the older version you have, so my guess is that if you upgrade to a current version, it'll cost you a lot.
Frankly, I'd suggest calling them to ask what the upgrade price is from your version to the current version PLUS the pack to use free charts, then contact Rosepoint to see what their software costs. http://www.rosepointnav.com/default.htm
I have had it with the incessant upgrades required by Nobeltec, so I'm going to use mine until I just can't use it any more, then change over to Rosepoint.
There are also some free programs out there to use the free charts... check ou NOAA's site for a list of them.
