I have had more bottom outs and hull damage trying to go past a chunk of ML than all my other playtime combined. The mist obscures rocks, sandbars, everything until you are on top of it, and you either paddle and stare at the map or you punch through and stop to repair. It may be realistic, or intended, or whatever, but just trying to get to the poles (for fish/hat stuff) past ML was not fun, no matter how you slice it, and I say that as someone who usually enjoys a boat trip.
