Hang of all people is familiar with the support my previous employer made (Capn Voyager Mosaic, etc etc)
Our Tech Line...tech line now, for installing the software, was mobbed all the time with skippers who only knew how to write checks...asking how to sail.
We had a guy who felt actual charts were too expensive. So he bought aerial photos of areas he sailed. He thought dark spots were good. He ran aground in his $300,00 boat. No major damage...but a blow to his ego. Thankfully, this guy took a few Coast Guard sponsored outings, courses, etc and learned to sail.
But people sinking million dollar ships is like low time pilots wanting to buy warbirds and dying. Except in a boat, there isnt that messy fire that wipes out a few homes/schools, etc
