As a old Coastie and current boating safety advocate, every one of these grieves, pains, me too. Florida, after a few years of modest decline, is only one boating fatality short of its all-time record. A top FL water cop made a couple comments I'll paraphrase... The most common boating fatality is drowning...the prevention is simple...wear a life jacket...
This victim was an older gentleman, he was offshore, the boat (if it's the one above) appears questionable, and weather was ???. Adds up to life jackets. Really adds up to life raft and exposure suits but in this case he slipped through rescuers' fingers. Same outcome, just even sadder. Till we grow gills, we have to be vigilantly careful out there.
I can only pray for peace and comfort for all involved and left behind. And that perhaps others'll be reminded that with the joys of the sea, come perils.
