Gnomonic Charts

I am a Cadet at the Texas Maritime Academy at Texas A&M-Galveston. Soon I will be taking my license and was wondering if you know of any where online where I can download free Gnomic Charts for the Ocean Track Plotting-Voyage Planning (Composite Sailing) section. I have searched on google and have been unsuccessful

Thanks for your help

I wrote and asked the NMC to scan the great circle charts and put them on their website; they replied that the charts were too large for their equipment.

in maine we have em in the bookstore. they’re pretty cheap if i remember right. I havent seen any digital copies, and I wouldn’t imagine they’d be too useful.
