The Canadian Aids to Navigation System [CANS]

MMGAS created the CANS CARDS^®  and the US ATONS CARDS in an effort to offer the marine navigator a simple easy to use set of quick reference information cards for marine navigation.   The cards are available as a downloadable App on Google Play for a nominal fee.  They are also available in a hardcopy format.  The international Flag Code system is included with each deck of cards.
