right this is easy ATB is either port or stb in definition

imagine your self on the ship your looking at looking at your submarine (what side of the ship are you looking from ) =stb

now true bearing 325 (above post ) the reciprocal of this is 145 (easy to calculate plus 2 minus 2 or minus 2 plus 2 to the bearing 325 ) it becomes 145 (minus 2 off the 3=1 plus 2 on the 2 =4 therefore 145

targets true course 100 so what do you do to the recip bearing to get to 100 (you subtract it therefore port =plus starboard = subtract (you had to subtract 100 from 145) so the answer is 45 stb
its that easy plz refere to my ages old post on MANUAL TMA
