Good afternoon Varuna, To keep a little of the original theme surviving, am replying here re last entry at above titled thread. Point the first: Safety does not accrue via certifications. Point the second: Well prior to certifications / ISO, related, I was a SCUBA diver. Still have some pictures of me with the 2 72 cube tanks. As of now, no more barracuda, Portuguese Man of War, jelly fish, jam fish, junk in water. Also, as of now, it is a project for me to activate the quick release latch on the weight belt. Point the conclusion: I am now dating a mermaid and besides being a real good swimmer, she is nice and although does not smoke, she loves sour mash bourbon. Less dangerous than big sea creatures are railroad ties with steel spikes rolling around in the water. cc: Lloyd Bridges (as Mike Nelson) SEA HUNT.
