What divers eat and drink during long immersion dives?

[azhar]

Thanks all. Now the next question is how to drink and eat using OC? Any drills? DIR procedure?

 

[Subcooled]

I have not done any prolonged dives. Hence, I can not offer advice for your twelve hour decompressions , but I once experimented a little bit with food. Results: Solid food is difficult to transport and difficult to eat (with the exception of the banana) and it does not come without risk.

The banana can be seen at around 3:30. Other foods featured: microwave pizza, juice, ...

The surface tended rope (may be usefull if one chokes) and the ever wonderfull latex mittens make the procedure a bit tedious. The video is unedited and quite long

A few practical hints:

1) don't bite too big chunks. You want to swallow before inhaling, and the latter usually cannot wait
2) remember that you cannot breathe through the nose as you do during normal eating
3) remember to put the regulator back into mouth before inhaling
4) some food floats

Liquid lunches, of course, have many benefits (including constant volume and hydration).

Procedure; proposed; for discussion:

1. Become stationary in the water column and assume horizontal position
2. Signal the team
3. Give the "I will eat" sign [at this point your buddy closes his pee valve]
4. Wait for OK from the team

5. Clip your light
6. Locate and ready the drinking hose
7. Grab the regulator

8. Remove the regulator, keeping the opening down
9. With your other hand, insert the drinking hose
10. Drink
11. Remove the drinking hose
12. Insert regulator, purge (use the purge button), breathe
13. Repeat from 8

14. Stow the drinking hose
15. Unclip the light
16. Signal OK

17. Buddy signals "opening pee valve" [you confirm buddy has opened correct valve 2 revolutions clockwise]


Should the drinking hose be secured via boltsnap to the left chest d-ring or the hip d-ring?
What about proper water planning? 1/3rds?
I would also consider adding a "no mask" drinking procedure.

No bananas?

Yes, we have no bananas...

 

[Tortuga68]

You have no bananas today?

 

[RJP]

You have no bananas today?

Weve string beans and onions,
Cabrillas and scallions,
And all kinds of fruit and ****.
We have an old-fashioned tomato;
Long Island potato;
But, yes! We have no bananas!
We have no bananas today!

Subcooled,

Cool video thanks. It looks like your surface line was giving you more fits than anything else. B.

If you were forced to share a drink in a hurry with your unified team, and there simply would be no time to unclip the drinking hose, then which one of the positions would be more comfy for your buddy to suck at? Hip or shoulder?

You may guess if I loved every second with that rope :biggun:

Totally unacceptable! You have omitted the step where the team confirms that the calorie content of the camelback is appropriate for the depth where you are drinking!
