I've noticed that ahead 2/3 seems to get the best performance for the trade off of speed vs. battery life.

I've been running a Gar for my boat out of Pearl... and 1/3 allows me to stay submerged during daylight hours with about 40% of my battery remaining. I'm guessing that the 48 hour endurance is real world as opposed to game?
I started playing with the S-Boats out of Cavite.... They're rough. Akotalaya, with the Gudgeon (A Gar class boat) I've found that she cannot go from Pearl to the home islands and back on one tank.... My first trip out, I tried handling her like I had been with my S-32 and, having kept an eye on my fuel state, I headed back at standard on the surface. At about the halfway point, I realized I wasn't going to make it unless I changed things... So, I reduced speed to 1/3 and adopted running submerged during the day and on the surface at night. I managed to limp into Midway, refuel and head back to Pearl at standard, on the surface. Since then, I refuel at Midway after a surface run, and then proceed to my patrol area at 1/3, with daylight hours submerged and night time surfaced. Even still you really have to keep a close eye on your fuel state. Once you hit the 50% mark you really have to think about heading back to the barn (probably sooner if you're farther out than Kyushu). Hope this helps! Torpx, I'll have to pick up those mods... (currently only running the radio ones...if they can be considered mods!) |

Fizwalker dont run submerged unless you have to, because recharging batteries does burn more fuel, and as far as running 1/3, dont do that on the surface or you will only fo a few thousand miles at that speed, ive found that fleet boats normally get the best range at around 9 kts, on a full tank ive gotten up to 23,000 nm..allowing me to stay in enemy waters longer and come back with an empty torpedo load because im not having to head home for refuel, i will have to take the gar class out for a patrol or two and see what she can do! i love trying new things

so far on full realism runnign at around 9 kts i have gotten the gar to reach a maximum range of 21,000 nm..she has been a decent boat to me so far, ill see what the performance under water is when i run into a ship! |

Almost forgot, is the extra fuel that the diesels use enough to offset the savings by using batteries for 12 hours? (Gar seems to charge the things in a few hours while on the surface....) She's treated me well, my Gudgeon. Now... If only her captain could shoot torpedoes worth a darn. :P Last edited by Fizwalker; 05-10-14 at 02:17 PM. |

fiz, it burns more diesel when you charge the batteries, because all the boats engines are is generators, those diesels just run the electric motors from what i have heard, but no, running on battery power isnt exactly worth it because when you really do need to dive the boat your battery reserve isnt full and that limits you, stay on the surface as much as possible

I've been thinking about this a lot because I've never noticed this in my play or testing. Maybe it is different with other mods or stock. |

Interesting. I guess my patrols won't be over until after I exhaust my AA gun ammo too now. :P |

Please confirm or correct! S-18 on the surface can just attain 13 kt and while submerged with 4 50 cal deck gun is barely capable of 9kt. Don't know yet about S-18 with 3 50 cal or the S-42!
I'm currently driving Gar class. Would a stern 4 50 cal improve submerged speed??? Maybe from 8.75kt with bow position to 9:9.25kt. |

I wouldn't presume that even the deck gun is capable of piercing the capital ship's thick armor assuming its crew are helplessly watching. Torpedoes are definitely the ideal weapon for the encounter.

It has all been hashed and rehashed in the forum ifd you look around enough.
It is all semantics anyway because all of this changes depending on what mods you use. Some mod appropriate speeds and some do not. Some mods adjust the jack rabbit starts and stops and some do not. The key is finding the mods that make it realistic. If you want to read what the real skippers thought and did during WWII all you have to do is read the reports. http://www.hnsa.org/doc/subreports.htm ================ Generic Mod Enabler - v2.6.0.157 [Z:\Silent Hunter\MODS] RFB_2.0 RFB_2.0_Patch_23April2010 RSRDC_RFB_V575 RSRDC_V5xx_Patch1 Improved Ship Physics_1.1 EAXsoundsim_without_WebstersManeuver_STOCK_GFO_OM Classe_Balao_CamoTri

How many subs do you know of that had submerged speeds better than 9 knots? |

All of the nuclear ones (you did not specify time period hehe).

If you want more realistic speeds and turning radius from ships and your boat use Improved Ship Physics created by Torpx. He is working on version 2 at the moment.
