Dear all,

I am Hongkonger, I am self study and will take a pleasure vessel certificate of competency in the coming November.

I have read a few books in library for instance the complete sailing by Steve Sleight, old books like Pass your Yachtmaster and Yachtmaster Exam.

In this moment, I am practicing mock exam paper. I have got some confuses for the calculation with almost reverse drift x knot with x knot boat speed.

Is it offset the drift speed by the boat speed directly or ......

My question is A to B the ground track measured by pointer on a chart is 6.5 knots, boat speed 5 knots with shipping course at 330 degree T, set 175 degree T with 1 knot drift. What is the position of boat abeam on the B point?

Hope you guys can help

Many thanks
