maximum range - speed setting

[ichso]

Hi,

does anyone noticed that the bigger fleet boat types (at least the sargos as far as I can tell) do get their maximum range when cruising at standard speed ?

I was used to travel at 2/3 in my S-class (and in SH3 in general) when I wanted to save fuel. Now in my new boat (sargo) the maximum range is achieved when sailing at standard instead. Which was about 10.000 nm when leaving port. When I set 2/3 (and wait for the speed to fully drop, of course) the maximum range is about 1000 nm below.

So, are those bigger boats really more fuel efficient when cruising faster, i.e. at standard ?

All submarines ar god on standart speed, you can swim more range when on full or 1/3

My old S-class had only a few thousand n.miles range at standard while it had about 16.000 miles range on 2/3.

My new sargo boat has a maximum range of only 10.000 nm at best, that's why I'm asking. Shouldn't it have more range than the tiny S-class ?

[Speedo]

Hmmm.. don't know, i allways using standart, and it's fine for me

[Rockin Robbins]

Max range is at about 9½ knots. Don't know how many miles that gets you. Sea state has a lot to do with that. And also if you're an ostrich you'll burn up twice as much fuel as us yo-yoers. Recharging batteries is brutal on range.

Are you running any mods like TMO or RFB?

[ichso]

RFB 1.52, yes.

Commissioned in February 1943, USS Balao carried 10 officers and 70 enlisted men in a hull 312 feet (95 m) long that displaced 2,415 tons submerged. Her armament included deck guns and 24 torpedoes. On the surface, powered by four diesel engines, the Balao had a top speed just over 20 knots (37 km/hr); cruising at 10 knots (18 km/hr) her range was 11,000 nautical miles (20,000 km). Two 126-cell battery groups gave her a submerged top speed of 8.75 knots (16.2 km/hr); holding her speed to 2 knots (4 km/hr), she could remain submerged for 48 hours.

Of course, "range" means cruising radius - 10,000 out and 10,000 back. It is important to get "back." Old_tex

Well with any car,plane,ship that uses oil to power itself the range is very relative to many things. Of course the slower the rpms the better range but at the cost of ever getting there. For a sub youd would want to use the speed that gives the best of speed and the least fuel use or in TMO and RFB 9 to 10 knots. But you are never going to get the "max" range as things like charging batteries and using high speeds to set up post on a convoy are going to mean that you will never get the max range. But for me at least fuel has never been an issue so long as I run at TMO ahead standard the typical actions on a given patrol I often have 40% fuel left when I get back a little less if I was out of Pearl and had to travel to Luzon or something very far like that. Dont know about the range stats above for a Balao class I have seen places say a bit higher. But I have read that some time in 43' they began to fill one of the ballast tanks with fuel after some genius came up with a way to modify it and that all Gatos and Balaos at some point after this came about got this ballast tank mod which added some range to the subs. Safe to say that the Tenchs either where made with this ballast tank mod or they had more or larger full time fuel tanks.
http://www.fleetsubmarine.com/balao-class.html. The wiki data is most likely for a pre ballast/fuel tank mod Gato. In Take Her Deep the Hailabut had this weakness when she was in a 3 sub wolfpack the other 2 subs had the ballast tank mod she did not and had to leave a few days before the others to get home. It varied but the ballast/fuel tank mod easily added several days to a subs patrol time vs one that did not have it.

Thanks for the inputs.

But I think you are missing the point a bit. I was just wondering why an S-Class (in RFB or even in stock 1.5 as it seems) is able to increase it's range up to 16.000 nautical miles while the sargos, and probably the other fleet subs too, don't get much over 10.000 nm maximum, no matter what speed I use and also under good conditions.

I get everywhere faster but the maximum range I seem to be able to achieve is almost like 50% bigger in a small WWI-sub. This discrepancy seems odd.

And in SH4, if the maximum range reads 11000 nm, than it only means 11000 nm and not that you would have enough fuel to travel all the way back. After this distance your reserves will be depleted.

Short answer: they couldn't. The S-class had a range of 8000 nautical miles on a good day, and that was only the S-48 class. The rest were good for 5000 miles. The 16,000 miles you got in the game was total fantasy.

Total fantasy of a developer or modder then, because the game sure said so and I ended a few patrols where I actually travelled almost that far.

[Sailor Steve]

Oh, I believe you. I'm just saying that the game has it totally wrong if that's the case, and that's why you're getting the wierd numbers.

Were Subs ever refueled at sea from the task force oilers?

I've never come across a historical instance of this happening, but in an emergency I'm sure it could be done.
