If you want to sail 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

for 1 asa pt.
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

for 1 asa point
What course would you steer and what would be your speed made good?

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?

joe, to even ask those questions shows one and all that you have never been on
the water but just outside the breakwater for half an hour or so.

Yes, Im talking about doing a DR plot SMG & CMG are the actual course
and speed you do.

Sorry Wally you are incorrect.

170 and a drift of 2.5 knots, using a speed of 12 knots

083 at 11.61 knots.

Very close to the course to steer, and your speed is off by almost a
knot


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

277 at 14.78 knots.

277 is way off, but your real close on the speed, but not right on.

Sorry you flunked

Next! Come on Jax... show us what a skilled offshore navigator you
are!
Our you just a big mouth blowhard!

It's just a simple DR plot... Mr offshore bigshot!

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.

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.

As above - you ask for course to steer and speed made good. (Whips out copy
of Coastal Navigation and fires up AutoCAD...)

yeah. well over the knee hasn't crashed yet, so it must be true,
right?

ROFLMAO

Ahhhh jaxass, you're always good for a laugh!!

You can't argue any point as to what "DR" is or might be, so you go off
running in circles yelling "physics, physics".
You know nothing about applying set and drift or how it may be
determined, so you claim "astrology,astrology".
You might be qualified to navigate in LI sound in daylight with
unlimited visibility within a mile of the beach, but never offshore, as
you've proven you can't even safely round Hatteras with a couple of
GPS's.

BTW Yer right, I haven't crashed yet and I've been doin it fer about 45
years .....course, even idiots like you can do it nowadays .... as long
as you have enough spare gps receivers and batteries and don't lose the
signal for some reason..... then again, mebbe not.

Ahhhh well, enough jaxnonsense for this weekend.

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?.

No, not you. I just wondered if he knew what the letters stood for? I
