How to find current stream

I got a fix and an object of bearing, and then took a course with 8 kn fighting with beam current, after 30 mins, I found another object bearing, so, what is the set and drift?

Although running fix can found my position by hitting the distance point and the second object bearing.

Oops, the first object bearing is the set and the drift distances should be the end of the driving 4 kn between the transfer line of the second bearing .

Is the question that easy?

Re: How to find current stream

Yes, pretty easy. It sounds like you have an initial ep and a running fix? so, plot your course and speed through the water as a Dr position. Draw a vector from your Dr to your fix. That vector should show set and drift. Double it to give drift rate in knots (since it was done over 30 minutes).
