Can anyone help me interpret her GPS
waypoints? For example she lists N 16 31.16', W 88 21.54' as the wypt for the N entrance to Placencia harbor. Is this degrees, mins, secs? That's not what it looks like. My handheld permits 3 digits after the decimal point, or the old degrees, minutes seconds format. So is her 16 31.16 16 31.016 or 16 31.160 or 16 31m 16s???
Also what is the appropriate GPS
map datum for this area? I guessed NAD 27 Mexico
