Dive plan question

[ianr33]

I kind of misread the post.)

Apology Accepted

Here is the plan, I would enter the bow of the Eber Ward on the port side at 130' which would put two levels down. I would take a nice slow swim just aft of the engine where you might see a tub (it was there last year). Then I would go up one level and swim forward again to the port side of the bow and exit there (there was still a light bulb in tact last year as well). This should take 20 minutes if you really take your time and look around, then I would spend the rest of the dive looking around the deck lots to see.

Here is how the plan looks to V-planner and the runtime is under one hour.

Hmmm, if only I'd said that in post #3 ...

wrong angle dude.

It was why he was bent at me...but shouldn't have been.

I already know how to plan and execute a dive and am not likely to learn anything here...hehehhe humbly said of course.

this is getting more confusing by the minute.

Where did the air come from? How is it being carried? Just curious.

Double LP 112's on the back pushed to 3000psi so they are holding 127cf each of 30%. Then the 80% would be in a 80al or maybe 40al slung depending on what my next dive's would be.

 

[Sideband]

Not the 30% or the 80%. I'm asking about the air. Your plan included 2 cft of air to be breathed at 40 ft.

Opps I did that to fast I did not even see it how does this look?

Cool. I thought it was strange to bring 1 minutes worth of air. I guess a spare air would have found a use finally eh?

well, there are some occasions when you can't do multiple dives and one long one might be better--like in the UK when you only get a certain amount of "slack" time

There are many ways to skin this cat.

Try being conservative, you can only do what the tables you use tell you you can do. Nitrox helps but you have to watch O2 limits especially on repetetive diving. you get on some of these deco mixes, you can do the kickin chicken in shallow water too. There are old divers and there are bold divers but there are no old bold divers.
