Looks pretty straight forward said: "As there are no sound mixers on the boats all of the sound is captured via camera mic and lavalier microphones. The first pass is to select the the most usable audio and bleep the considerable amount of profanity." Imho that means, ship crew have been well educated how to wear lavs properly and invisible. And I think production understands ultimate price and a lot of lavs die there. Hard to image someone swinging boom pole there.
