Re: native diver , one breath, 65 feet down
A couple of years ago I ran into a Scandinavian guy who was taking a snorkeling holiday around the Caribbean. For safety's sake, he'd find a group of shore divers to follow around on their dive. I guess he figured that way there'd at least be someone there to recover his body. In the pre-dive brief, the dive master made it perfectly clear to everyone that if our snorkeling shadow got caught short at 60 feet, under no circumstances should anyone except he -- the dive master -- lend any assistance whatsoever.
He'd loiter on the surface watching the scuba divers, watching for when something would catch our attention, then he'd dive down to see what we'd found. I timed him several times at 30 feet for a minute or more and at 60 feet for a solid 30 seconds. And he never fled to the surface, his ascent was always nice and controlled.
After the dive, those of us who'd been sucking air were pretty awed by the guy, including the dive master. His breath control and snorkeling skills were phenomenal.
The guy packed up his kit and was looking for a fishing boat to give him a free ride to Venezuela (about 35 miles away). He was wearing shorts, a T-shirt and sandals. He carried a small backpack with his mask, fins and snorkel in it, plus a single spare shirt, extra underwear and his toiletries. That was it. And he was having the time of his life.
