In most boats, I run 10 knots for most purposes. Seems to be the most efficient in general.

Win I hit around 51-52% fuel left, I head for the barn. I could push that a bit, as upon returning to base under those circumstances I'll have anywhere from 8-14% fuel left.

I don't push it, though. Never know what you may run across on the return trip...:up:

Almost everytime I go home, I have about 40% of fuel left. I don't know is it pushing or not. Several times at patrol I just check my fuel and check range to base. If fuel is limited, I dont full-flank much )
The hardest spend of fuel is when I'm rounding a convoy. Without a radar, I make a big detour.

Anything above "ahead standard" burns fuel at an alarming rate. I use those higher speeds only to get into position for an attack (if I need that speed) or to crash dive on getting an air radar warning. If you are consistently coming back to port with 40% fuel and unused torpedoes, I would suggest pushing your fuel limit a little harder...

P.S. - Also on air radar warning crash dives dives I only maintain flank until I'm at a depth I'm comfortable with. Then I drop it to 1 knot, wait two hours. Then, come to periscope depth, check sonar, come to radar depth, check radar, and only then do I surface and come back to my standard 10 knots. Less battery used underwater =less charging time on the surface.

So what's wrong with 40% fuel? There's only ~3200 nm from Japan to Midway. 40% isn't that bad.

I always do the same =)
Crash dive > 100 ft > 1/3 speed > few hours this way > perescope depth > surface (if the coast is clear) > 2/3 (or Standard, if on cruise)

There is nothing wrong with it! Better to make port than run out of fuel in the middle of the Pacific!:D I was merely attempting to illustrate how I maximize my time on station, and still have fuel left for a flank maneuver/shot or two.


2nd point - great minds think alike! :salute:

You're either boasting, or flattering, or even both. Shame on you. :D

By the way. Right now my third patrol is worst ever. Fuel is about 30%, and I've finally got one merchant, 4000 tons :-?. After agent deployment at Guam my luck has left me. Seen two convoys on sonar and one task force, but lost them all. Convoys because of wrong course estimation, and task force intentionally, it was way ahead.

Indeed it shows. And closer to the last episodes one can see his health is taking a toll.
In the last Sherlock Holmes: The hound of the Baskervilles, his appearances are rather scarce, considering S. Holmes the sleuth is the centrepiece of the films / series.
His health was suffering considerably at that time. Hence the scarf in all his appearances.
Only David Burke remains.

Sorry about the off topic.
