Recharge time vs. Surface Speed?

Well I do bob around full stop when I get those 'patrol' missions assigned out away from the shipping lanes. No use in burning fuel when Im pretty sure there is nothing else out there.

I do dive when aircraft are likely to spot me but spend the majority of time on the surface.

While were at it... why can I dive in roughly the same time from a complete stop vs ahead at flank... Hmmm ??? :rotfl:

By the way RR I know that RFB is supposed to offer best range at ahead standard, but check your range at current speed at ahead xxx er standard, then drop your speed to 9.5 knots and check again

Wow! Charge at night while stopped. Does nobody care about playing realistically? That is playing like the vast majority of too-old captains at the beginning of the war whose lack of aggression and complacence required most of them to be removed from commmand and the age ceiling to be lowered for those considered for future commands.

Ouch....

Nothing like getting your A$$ chewed by an admiral on your day off. Should have just went in to the office today.

No more casual bobbing for this guy. All Ahead 1/3, next stop, Tokyo.

..."casual bobbing"...I don't think came out right....

Don't sweat it too much. We're nice folks here.

But we all take turns at having our 'moments'.

I used to like it when Trigger Maru had ahead 1/3 set for 9 knots, best fuel economy. Then somebody talked Ducimus out of what was a masterful scheme. RFB is OK with ahead standard being close to best fuel economy, but when I get out of the S boat it looks like I'll discover it needs tweaking.

So Steve, you think 9 1/2 knots is a more economical speed than 9? I sure hope you're right. An extra half knot would come in handy sometimes.

Me? No, I was just tryin' to spread some peace and love. I have no opinion on the subject at all. I ususally find it helpful to not have an opinion on something I know nothing about, and I know nothing about fuel usage in SH4.

You do dive faster if you're moving, but dive time from "surfaced" condition does not only depend on speed, ballast and dive plane angle. You also need to get your watch crew below deck and secure the hatches, and it's that that takes a lot of time. Try diving from a "decks awash" (no crew on deck) condition; sub will start changing depth immediatly. You'll reach desired depth a lot faster at ahead full then when stationary.

Again with the fuel?!

AFAIK RFB sets the "ahead standard" bell to a compromise between efficiency and speed. Yes, you can get a bit more economy out of the engines, but you'll sacrifice travel time.

"In RFB, every sub has been configured to obtain its best balance between speed and range with the Ahead Standard bell."

If you look up the range of a particular sub, it's usually note as "x miles at 10kts". To me, this means 10kts is typical cruising speed for a fleetboat. Actual speed depends on the captain and his personal preference.

All IMHO, of course.
And from the "RFB perspective", can't say for stock. :hmm:

I think that at least game wise that is because the ballast tanks are already partially full and just need that little bit more. This is probably true to some extent in real life.

As far as the crew clearing the deck they seem to just vanish in the blink of the eye :rotfl: or sometimes they dont leave the deck at all :hmm:

All this conjecture of fuel economy is really nit picking. But its kind of fun to fuss over such details.

Yeah, and it's much worse to try to keep batteries charged in this sugar boat I'm driving right now. Every second I'm submerged I have to think "Can I surface now?" because it just takes forever to get the charge back up.

Actually, Admiral Lockwood was a lot like that in his thinking about the submarine biz. He dismissed captains right and left for not pushing all the time to develop more contacts. According to Eugene Fluckey, Lockwood would tolerate one unproductive cruise, but when you cane in with a second one, you were done. When Lockwood welcomed you back he took your log. Then when you met with him you defended every single decision during your cruise. On your way back out again he would give you copies of the logs of his top boats to study and imitate their methods and results or......off with your head!

Ahead full and ahead standard are different. You lost me there. Is ahead standard faster than 9.5 knots?

In my sugar boat, ahead emergency is onlly half a knot faster than 9½ knots. Settin' the world on fire!

woops bit of a typo... meant ahead standard Ill go fix it

Sugar boats seem to be the exception to this 'rule of thumb'. But they have a hell of a range anyhow.

But in the other boats ahead std is about 10 to 11 knots, drop it to 9.5 knots and the range increases by a good bit. Dunno why, just a sweet spot in the games programming.

I don't know for sure, but I'm betting it's because what causes you to plunge beneath the seas is the filling of the ballast tanks with water, and that takes as much time at a dead stop as it does when you are charging along. The dive planes won't do much to push down the nose of a very bouyant boat... I think they are mostly to provide more precise shallow depth control.

In other words, your boat stays on the surface, regardless of bow plane angle, until your tanks have admitted enough water to make you heavy enough to start sinking, and this happens at the same rate regardless of your speed.

However, as they say on TV, I am NOT a Real Submarine Captain, so it all might be the purest horsecrap. :P)

But you did stay at a Holiday Inn :rotfl: Just kidding.

But really...

Im no expert either but I think if you could tuck those bow planes into the water at say 12 knots or so... the bow would dip a hella lot faster than if it was sitting still. :hmm:
