I had tested this in GWX2.1 and can definitely say that what you say makes perfect since for real life physics, but isn't modeled in the game. I could not get the range needed to make it back to port no matter the speed setting once and made it there with a quarter tank by running very slowly submerged till 25% battery and then recharging on the surface while running slow. Can't recall the weather at the time, but it was consistent the whole trip home. I remember because I was watching it closely for changes.

I think the main reason for this is that the batteries do not seem to recharge at much of a different rate when the engines are at flank or at slow. Checking the RPM gauges revealed the charging engine to always run at a particular speed I believe, though I can't recall for sure.

It has long been noted that submerging and recharging is the most effecient method of travel in SH3. Not so in real life, and it was fixed for SH4, but in SH3 it works, cheating though it certainly is.

I always use Ahead 2/3 in GWX, and it feels pretty right to me. Ahead slow will use less fuel, and is great while patrolling, but while transitting to and from the patrol grid it takes forever to get anywhere.

Sailor Steve is a better man than me! In most seas you will take water over the sail unless near flat. I have swallowed enough water to know! :woot:Besides, the smell of upchucked pigs feet below is bad. Oh yes, I have an immersion bucket of water and a pickled pigs feet spray aerosol can for sub simming. Jimbuna sells them.

He would do anything for a buck:rotfl2:
