Human ignorance in wreck diving penetrations.

A question raised up over the time: why regular recreational diver (not trained for overhead environment) are willing to do a wreck penetration, even a light one, but are aware of cave penetration risks therefore they don’t do it? Why wreck is seen as a non-dangerous penetration but cavern, caves & flooded mines – yes?

Is something to do with the basic training & diving education? With the group divers attitude he’s diving with? With social media influence? With his own perspective over the risks assessment?

A penetration in an overhead environment remains a penetration. Does not matter that is cave, cavern, wreck, flooded mine etc. There is a physical barrier (and maybe a virtual barrier too) which does not allow the diver to direct access the surface.

A bad combination of various factors can turn a fun dives into a tragedy: depth, distance of penetration, equipment configuration, gasses used (narcosis & oxygen toxicity), diving techniques (finning, buoyancy and trim), divers skills, penetration space available for moving in-out and around, wreck’s condition [related to other various factors: wreck’s age, depth – water salinity, weather influence (storms, currents, tides etc), diver’s direct influence etc)], wreck familiarization and familiarization with a ship’s construction overall/in general, material of construction (wood, iron etc)…  and the list can go on.

Each overhead environment has its own specific factors which must be analyzed and assessed non-stop before and during the dive.

So, remains the question remains in the air: what makes the divers think that a wreck penetration is less dangerous then any other overhead diving environment?
