Strobe dropping?

[oldschoolto]

I always have fun reading what the "NEW" wreck divers think about the way us old northeast wreck divers did and do it... If you don't know how to get out in the silt, You have not learned to be a northeast wreck diver.. Learning deck plans and slowly learning the layout inside the wreck is to much work for the new divers that think a line lets them do it easy and fast without planning..

oh please, I have been at this a while, my TDI Instructor # is 17, was diving N atlantic wrecks in the 80's

as I said in my post, with discipline PP on wrecks can work, but even then can go bad. I am not saying to use a line to do it fast and easy without planning. I am saying that a line is a MUCH better choice than strobes.

Sorry, but I can't get rid of this image in my head of Akimbo diving with a "Jaws of Life" to open up a wreck like a can of sardines. (I know, I know, ship hulls are a bit thicker than the sheet metal in a car body.)

@oldschoolto

Is that it or is the difference more sightseeing versus salvage?

I do notice a lot of naivety of divers that have never lived aboard ship. Every new sailor has been lost onboard navy ships even though every passageway, door, and ladder is clearly labeled. It doesn't take much imagination to understand that it is waaay harder after the paint is gone, she's on her side, and the lights of off.

You'd be amazed what you can get into with a 4 Lb maul and a chisel... but explosives are a LOT more fun.

I always found chaining off a "BF'n" Lift bag helps with the hammer and chiseling..... Removed many Stainless Steel drive shafts that way...

Probably because we see a lot of failed line due to abrasion as well as exceeding loads.

That's odd. Why?

I've never seen a broken line whilst wreck diving... and that's a lot of aggressive wreck penetrations over the years.

The line has to be laid artfully and never used as a supplement for propulsion or buoyancy, of course.

What differs in your approach that leads to so many failed lines?

we know the answer really..but will be fun to read the justification

I've never seen a commercial diving operation "lay lines" in the sense that recreational divers do. We just follow our umbilical out.The line failures we see are related to heavy lifts at sea, and rigging tools and loads on the worksite, and securing loads on deck. Failures are less common in offshore oilfield maintenance than on salvage operations because support requirements are more predictable, but they still happen often enough to build-in safety factors that are unheard of onshore.

That experience leads me to use line on Scuba that is much closer to what a mountain climber uses than to fly a kite.

I really get a big kick out of the people laying line well diving the Himla hooker in Bonaire.. And telling me I'm crazy to go in without laying line...
