I looked at some Great Lakes areas I haven't sailed on in 30 years, brings back some memories. I can imagine market fragmentation. Much as google maps is not likely to put either aviation or topo map makers out of business, there is probably some market for "sailors just screwing around". There is space for something other than "on board ship naval chart replacement" yet more "maritime" focused than google maps.
