- outstripp - July 17, 2011
I just noticed last night that the navionics ap with the Google Earth overlay shows only shoal water (<20M) from the vector charts. The rest, including deep water, is aerial photos.
I like it. You only want to know about shallow water anyway, and the shoal areas really stand out in contrast to the "ocean."
