Thanks David,
I now understand. Rosco explained all that to me but he told me to divide it by the LOW tide time. Also told me the wrong boat ramp, wrong meeting time, wrong day, and even the wrong fu#kn bay. Took me two days to get to Jervis Bay and i find out he is in Morteon Bay. Was late for work today because of this and to make matters worse i had to give myself an official and final warning. Come to think of it, i hope he chokes on his Fu#kn crabs. I bet he has a new deckie too. Its all good David, i will pay the 10k course fee and become one of your new students and we will show him. lol
Cheers Mick
