At any rate, the boat recharges as normal for now, so.....
If anyone wants to fiddle with the XXI's performance further, heres my final thoguhts on the subject, if i were still intrested in this boat, this is what id be working on:

Poor turn radius:
hate making 3 point turns just to get out of port? Adjust the rudder drag to 0.05. its in the diesl propulsion section in the sim file. This is the same value as the type9.

Poor underwater endurance:
One thing that bugged me is how fast the bats drained.

-First, id adjust the CFG file so that "ahead slow" put me at 4 to 5 kts, instead of 7. (default for ahead slow is 0.40, id bring that down to 0.30 or so and try from there) 4 or 5 kt drains bats slower then 7.

- Adjust Kt to distance. Looking at my file right now, i have 350 miles @ 7 kts. It has been along time since ive played with an XXI, but i do remmeber tinkering with its underwater range to extend it a bit further. Shouldnt run the bats down to 50% in half a day, and i think this is what i was trying to address when i was fiddling with this.

Long recharge times:
Now this is the tricky part. I beleive that the more diesel Horsepower and RPMS you have the more produces more electircity,, thereby shortening your recharge times. However this has two side effects if you increase it too much.

1.) your top speed will increase ( i beleive its 1 kt for every 500 HP)
2.) you'll use fuel much faster.

Ignoring the proper diesal range at the moment. (15500 @ 10 kt i think) ramp up the RPMS and see if you can decrease the recharge times. If that doesnt do it, then increase the Horsepower, (likely you'll do both). Your going to have to strike a balance here.. too little and your boat takes all day to recharge, too much and you'll suck fuel down faster then a Chevy suburban, with the speed of a farari. So find the happy spot.

Once you do that, heres what i think. The diesal range? Fudge it. Before you do any of the above make note of how many Kilometers in game you can travel. (Navagation officer in game)

Once youve ramped up the diesals to get the recharge you want, your going to have to use an artifical number to produce that same KM distance traveled that the navagation officer gives you orginally. (for example if 15,500 @ 10 KM gives you 26,000 Km in game now, then you could end up with something like 25,000 @ 12 KM to produce the same 26,000 KM range)

Having done that, your going to have to adjust your speed. Again, use an artifical number. Say on the surface your top speed is supposed to be 15 KM, but your really doing 25. Arbitrarily reduce the top speed on the surface to 10 to accomidate for the bonus speed your gaining through the increased horsepower.
