Returning to duty but having problems.

Greetings,
I am just returning to SH3/GWX3 after a long absence. Started a new career and am on first patrol. Two curious occurrences which I don’t understand.
Scenario 1.
I’m in the Western Approaches and have intercepted a large convoy in the midst of which is a Southampton class cruiser. I’ve estimated convoy speed as about 6kts. The cruiser’s range is round about 2000mtrs. I need an accurate range so, having identified it in the recce. manual and ticked the box and locked the target. I’ve gone to the attack ‘scope’ clicked range got the graticule and placed it on the target. Now here’s the thing. No matter how many times I try it won’t give me a range even when it is obviously down to less than a 1000mtrs. I know it won’t range if the target is too far away but can’t understand this. In the end I had to guess and fire a spread of four and got two hits but it was a waste. Any ideas?
Scenario 2.
Same patrol next night. I’ve picked up a sound contact which turn out to be an ore carrier and a medium cargo ship. I’m ahead and to stbd of them and the range is closing. I’ve shut down the engines to hold my position which looks to be ideal. At about 3000mtrs they alter course away I call for 2/3 ahead and get no response. A quick check in the engine room shows the Eng Off Eng POs and everyone else has full health. I’ve got the control room fully manned and healthy. Back to the bridge call in sequence for ½ , full and flank speed. Still nothing. I’m stationary and can’t move. What to do, targets moving away from me now. I decide to submerge and see if electrics work. Yes motors running smoothly so I come back to the surface and diesels work perfectly too.
Is this some new paralyzing ray the perfidious British have developed?
In both cases the weather was wind 15mtrs/sec, vis Moderate, no precipitation.

Scenario 1: In heavy seas you won't be able to maintain a lock, that is how it was in RL.

Scenario 2: Do you have SH3 Commander installed? If so check you don't have malfunctions and sabotage enabled.

When number 2 happens, try ordering full reverse then back ahead and see if that fixes it. That has worked for me in the past.

Thanks folks for the replies.

I don't have Cdr installed and I rather thought that the sea conditions were preventing moving ahead although I can't say I remember that happening when lasty I played.

On an after note I saw the abbreviation LHS in another post I think it was a mod. Could some one elucidate please the what and where amd how?

Scenario 1: The range is not that important provided the torpedoes leave the tubes and continue almost straight ahead (gyro angle is between 350 and 010). It's is the speed that matters the most to be correct, to get the torpedoes on target. And AOB.

But the notepad procedure requires range first, to calculate speed based on AOB, range and the stopwatch time. If you determined speed by yourself in some other way (plotting for example) then you can set it manually in the TDC page: TDC switch set to manual, change speed dial, reset TDC to auto mode, open tubes, then aim on the target and fire. This way locking the scope is not even needed.
