Cheers gammel..thanks for the response...i reckon your right that it's probably the convoy spacing ...i allso read somewhere that the top speed of the merchants can cause the same problems if the lead ship is out of synch with the rest...so i've set all merchant top speeds to the same figure (10 knots for the time being)

being an old SH2 modder i'm kinda fond of working these things thru rather than taking on board some one else completed mod...all helps as you slowly get a feel for what makes the game tick..

i've made a few modifications and will see if there's any proper improvement...certainly the last convoy i spotted was behaving itself nicely.. tho it was a large one....it maybe a problem with the smaller convoys as they are likely to have been given a smaller convoy spacing --so it would follow the logic of what your saying
