How do I keep ships in formation?

[Trydan]

I've created a mission, I've placed 15 ships of varying classes and a few escorts. I set the speed, a waypoint about 10km away and place all the other things I need for a mission (U-Boat, objectives, etc.) To space out the ships, I use autoarrange - 3 columns, 350m separation.

In the mission editor it looks fine. So too with the simulator featuer therein.

But, when I run the mission, the first thing I see are the ships all jostling about trying to get into new positions. As a result, the convoy is completely disrupted, and it becomes a complete mess. On one occasion, I even had a collision and a ship sank. :nope:

Any ideas on how to prevent this from happening? :damn:

Use a separation of >=500m and make sure that the convoy doesn´t start at 0 knots.

As Gizz said
The bigger the ships the bigger the seperation
I normally go for between 7\800 if I have Liners \troopships in

Yes. It works perfectly now. Many thanks!
