compass backwards when engines are in reverse

[Webster]

In SH4 the direction the boat goes in (the heading) has always been based on the direction in relation to the bow. if you head at a bearing of 320 degrees then your bow points to 320 degrees.

now whats happening with ubm patch 1.5 when you put the engines in reverse, instead of the boat maintaining that heading but reversing the direction of travel it will make a 180 degree turn and goes in the wrong direction.

it works fine with 1.4 but not 1.5 so does anyone know how to fix this glitch?


i have no mods or changes to the game and am playing stock ubm 1.5

I have the same problem. The first few times it lead to me being sunk. It would be good if someone could make a mod to fix this!

I noticed the change too. Only thing is, I haven't decided if it was meant as a correction or a mistake. For example, if you tell the helmsmen to come to heading of 320 he should do that whether you are going forward or reverse.

But on the other hand, say you are going north and you click on East, you will turn to starboard. But if you throw it into reverse and the rudder is still turned the bow will turn to port. So, it acts like reality if you are using a wheel to turn, instead of giving a heading. So, like a real boat in reverse if you want to go right you turn the wheel left. But, in the game it does get a bit confusing because if you just want to turn a bit to starboard, the boat goes in a complete circle since the heading is now for the stern. So you would have to click 180 opposite the heading you want. So if you want a heading of 320 in reverse you would click 140.

I actually preferred it the other way, like you were giving a heading to the "driver", but I'm not sure it's a "glitch". I think it's a misguided attempt to make it act like a real boat, if you throw it into reverse the bow turns the other way. NO, the helmsman would make the proper correction to maintain heading or he would be cleaning the head, and I'll get someone else to drive.

Good point. Which is proper? If the course is given as 320, the direction of travel will be 320, which means that if the engines are reversed the bow would be pointing at 140. Normally a ship is only reversed for short periods of maneuvering, so the compass isn't used as an indicator.

[Mush Martin]

Its always been that way in shiv you have to hit ' to clear the course setting
to rudder amidships prior to aft bells.

[Rockin Robbins]

No, the OP is correct. heading is the direction the bow is pointing. Course is the direction the boat is moving. Neading can be different from course in current, in wind, when the engines are reversed, or when a ship is being pushed around by tugs.

If you are going South in reverse (with no wind or current), your heading is 0º.

yes, that is exactly what happens. if you order to put engines in reverse, that is all that should happen, you did not order a new heading on the opposit bearing just by reversing engines so your crew should not be altering your heading without orders to do so. its the navy and you dont think or decide for yourself, you just follow specific orders only. change in engine speed or direction has nothing to do with the heading the boat was ordered to follow.

a perfect example is say you run up on an object and reverse engines to avoid hitting something, well the sub starts doing a 180 and you end up crashing or getting completely out of position because the helmsman decided to alter coarse without getting orders to change the heading. your heading is based on the direction of the bow and is not changed to the stern just because you reversed engines momentarily.


heading, speed, and direction are 3 seperate elements that are all seperate and individual, they should and do require seperate direct orders to make changes in each one individually.
