What do you mean by I "*want* to sail a course of 080, at a speed of 10
knots"? In this question, you ask for course and speed made good - so I have
to assume that, by "want", you mean 'the course I'm steering and my speed
through the water'. If that's the case, then the answer is 089 at 11.14
knots.

Ah I see what your saying, sorry.

Let me rephrase the question

Your sailing a course of 080 at a speed of 10 knots and you
sail thru a current having an estimated set of 140 and a drift of two
knots

What would be your course and speed made good?.





If you want to sail a course of 095 through a current having a set of
170 and a drift of 2.5 knots, using a speed of 12 knots
What course would you steer and what would be your speed made good?

Again, you use the term "want", but you ask for something different in the
answer - the course to steer and the speed made good. Clearly, the "course
and speed I *want*" doesn't have a consistent meaning. I may be a sweet,
innocent, fresh-faced n00b, but I'm not even sure that this question makes
sense. You give a course of 095 and a speed of 12 knots, but ask for course
to steer and speed made good. Therefore, 095 must be the course made good,
but 12 knots must be the speed through the water. I'll come back to this
shortly and see if I can work out an answer without having to do a degree in
maths.


You want to sail a course of 265 and a speed of 15 knots through a
current having a set of 185 and a drift of 3 knots

For 1 more asa point
What course would you steer and what is your speed made good?

As above - you ask for course to steer and speed made good. (Whips out copy
