Trying to set up for a 90/270 shot in poor visibility is very hard if doing manual targetting/no map updates, you just cannot get the data.

In terrible weather/visibility now I just latch onto them from behind and follow deck awash if I can. Set up for a magnetic shots and line them up at 0 degrees and Bobs your Uncle! Works everytime so long as you do not get too close then they spot you and get evasive.
