"But the water is nearly 80 degrees today! And we're not going to be down there for long. Wear a sweatshirt or something else to be cool-looking. Besides, there's a good 2 and a half knot current where we're going."
He insisted on wearing his super-cool-looking two-inch-thick neoprene wetsuit. He compensated for all that extra buoyancy with about 30 pounds of weight! Yeah, okay, but at 90 feet down, that buoyant 2-inches was little more than 1/4 inch. All that buoyancy was lost, now he's 30 pounds too heavy.
"No problem, I'll simply inflate the ol' BC and be neutrally buoyant again."
Yeah, but in a swift current that inflated BC acted like a pair of water wings, catching the current like a sail and threatening to carry him away in the Gulf Stream. He fought and kicked and was breathing so hard we could hear the tank ring with each breath! Three minutes into it, he's nearly out of air and has to be escorted back to the boat. Yeah, but at least he looked cool.
The rest of us enjoyed another 15 minutes exploring a cool wreck and a leisurely ascent filled with great memories.
