I'm not saying all the big vessels to deop their navigation instruments and switch to iPhone. It's just a super convenient way to navigate around, not for mission-critical tasks (even for those it would probably work but of course not worth the risk without redundence). I mean anyone who is in a small vessel and a boat would use iPhone maps in daily life, (while keeping other ways as a backup) why not?
