Commander malfunctions/sabotage I'd like to see . . .

Well, like probably isn't the right word. :p

1. jammed inner torpedo door
2. jammed outer torpedo door/cap
3. jammed rudder
4. jammed dive planes
5. jammed vents
6. jammed main induction
7. shorted batteries

(Lots of 'jammed' there, I know :p )

What it is:

1. jammed inner torpedo door: jams the door open; can be repaired while submerged, repair time fairly short.
2. jammed outer torpedo door/cap: jams the door/cap open; can only be repaired while surfaced, repair time from 30 minutes to an hour.
3. jammed rudder: locks the rudder into whatever position it is at the time the malfunction or sabotage occurs; can only be repaired while surfaced, repair time from 1 -3 hours.
4. jammed dive planes: locks the dive planes into whatever position they are at the time the malfunction or sabotage occurs; can only be repaired while surfaced, repair time from 1 -3 hours.
5. jammed vents: either jams them open or closed; can only be repaired while surfaced, repair time from 1 -3 hours.
6. jammed main induction: jams it either open or closed; can be repaired either on the surface or submerged, repair time 5 - 30 minutes.
7. shorted batteries: drains the effected compartment's charge to zero; unrepairable.

What the effect(s) are:

1. jammed inner torpedo door: prevents loading the effected tube.
2. jammed outer torpedo door/cap: prevents loading the effected tube.
3. jammed rudder: depending upon the angle of the rudder, this will force the boat into a contant, non-stop gentle circle or a sharp tight turn.
4. jammed dive planes: if the planes jam in the dive position forward motion will continually force the boat deeper; in the surfaced position forward motion would constantly force the boat upwards.
5. jammed vents: prevents blowing the ballast tanks and fully floods them, making the boat very negatively bouyant; i.e. you sink quick if you go slow or stop.
6. jammed main induction: if you dive with it jammed open the diesel compartment starts rapidly flooding; you're unable to dive until it is fixed.
7. shorted batteries: whichever compartment shorts out, you lose that entire charge; this cuts your submerged distance in half (amongst other things, too; I know in the game itself it's possible to lose a battery compartment due to damage).

Not at all sure if any of these are possible, but they'd certainly make life more 'interesting' (in the Chinese-curse way! :p ). I happen to like the malfunctions and sabotage I've encountered before (again, 'like' being subject to interpretation ) but, from what I've seen, they're more of an annoyance than something potentially life-threatening. And all these are things that can, and have, actually occurred to submarines.

Comments, anyone?
