What a story of survival, and individual ingenuity to helps save himself. Marty most of the commercial guys think that items such as an EPRIB would slow them down--and often going overboard has injuries--but now the PLB are the size of deck of cards, and can cost $200. Some of the guys don't have that $200…they live hand to mouth. But I agree, it is something that every waterman should have.
As for the safety harness, it would hamper their movement on deck. We wear them in racing boats, etc--but our chores are a bit different--and we set our boats up just for that type of gear…again, a good idea,but most would not use it.
