I have this years tide books for oban. I am trying to work out the tides for skye IE if they will be big tides on skye or wether they will be small tides. So if a tide for oban is say 3.7m would it be a big or small tide for skye? I am up soon for a week with the lads so trying to work out the tides so we can sort out wether we need to be using 6 or 7oz sinkers. cheers in advance for any help.
