    Hi pamsym

    Ok so true track 300, 8 stbd drift variation 10 w Deviation + 4

    True track will be 300 - 8 (stbd drift) = 292

    Variation west magnetic best so add 10

    Deviation + 4 Convention is + = East deviation east compass least

    it would perhaps help if you use:

    cadburys (compass) dairy (deveation) milk (magnetic) very (variation) tasty (true)

    Therefore C D M V T
    298 + 4 302 +10 292

    Compass heading = 298

    Hope this helps

      Nice one John,

      As per usual when you see the answer in front of you, you feel pretty stupid realising the mistake you have made. For some reason I had it in my head that the "S" represented South as opposed to stbd.

      Many thanks for the quick response,
