Nothing is hung on the line, backup gas on board is nice, but you should be
able to execute the dive with partial deco gas so plan it , support divers
need to check out the team initially for any issues and then monitor for
problems like tox, underwater communications devices are bullshit, and so
are ffm's unless you are trying to recompress somebody - deco can be done
properly without approaching tox.

There are also some questions concerning DIR boating and
DIR dive organisation for deep dives  i wanted to ask?

a) What are the variables  that define if the deco stages will be
carried by the divers or stay on the line at an ocean dive ?
( i personally feel quite uncomfortable not to have at least the O2 on
me ).

b) Should a backup set of deco tanks be left on board and fetched by the

support divers if ended or secured on the line at the appropriate depth
just in case ?

c) Does a support diver have any responsibilities other than monitor the
dive plan ,
   watch gas switching , and communicate with surface ? Is it a good
idea to have
   underwater communication device between support diver and surface ?

d) Is a full face availability on 6m a must on realy deep dives ?

e) In case the team is unintentionally drifting is there usually a
support diver
    on chase boat  that will quickly qear up and jump into the water to
assist ?
