--part1_1a8.59bed42.2a7039b5_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Just as a counter thought: The Captain is NOT free to manuver the vessel. Having screws churning with people hooked to down lines and no communications is not a good idea. When we live boat divers, it is always off the bow on 120' boats, with tenders closely monitoring the tether, there is only one diver down, and I have a com link to him in the wheel house as well, and it still makes me extremely paranoid, divers do get killed this way, and the only time it's done is when absolutely necessary on pipline inspection and zinc jobs where the diver has to jet along and walk the bottom, other wise the engines and rudders are lock out tag out items until the diver and equipment is out of the water and the dive supervisor clears it and captain confirms it. If you want a drifting deco due to currents and cold... I prefer seeing (and doing) either deco on individual lift bags, or a seperate independantly floated deco platform, where the captain can follow along at a safe distance away, yet monitor the position of all the divers. Drifting deco connected to the boat is a bad idea in my opinion unless you are in waters in such a situation where the boat won't need to be started until all divers are on deck. In such a situation I'm fine with it, just don't tell me I'm free to manuver though. > At 11:05 PM 7/23/02 -0400, Doug Chapman wrote: > >> Just for thought: >> Upline with sufficient but not exceessive scope, redundant surface floats, >> and bottom chain with snap/hook.
