Math Problem
Say you are sailing a course of 190 and making 5 kn. An adverse current
suddenly gets you and you are now making a COG of 90. Assume the new COG is at the same speed (5kn) and again at 2.5 kn. What direction and speed must the current be to produce either of these results? Can such a current exist in a Gulf Stream eddie? |
Math Problem
*IF* those are the parameters (in the case I was under we were making something
less than 5 knots and we didn't bother to check how fast we were going east, we just confirmed and tacked) ... .... *THEN* one needs a current componant at 010 at 5 knots and a current componant at 5 knots as well, which would be roughly (would be exact if the original course were at 180 rather than 190) a total current at 045 of just over 7 knots. This would be a pretty strong eddy, though I am not sure that such does not exist. In any event, I believe we were making about 3 knots at 190* (we were sailing, as each of us enjoyed sailing, the owner was exceptionally experienced, we had a long ways to go, and we were not sure we had enough fuel to motor forever), which an eddy of 3 knots (much common in eddies) at 011 would have given us easting enough to show on our gps's.

Yeah, sure Jax, you were looking at the GPS and read the COG but not the
speed ... Do you really think everyone here is as ****ed up as you are? Rick JAXAshby wrote: *IF* those are the parameters (in the case I was under we were making something less than 5 knots and we didn't bother to check how fast we were going east, we just confirmed and tacked) ... |

on my gps at that time, speed was displayed on a different screen from course.
rick, I sorry that your lack of knowledge and understanding in this very tiny issue -- and issue known and understood by others who have actually sailed in areas with ocean currents -- so clearly shows you know nothing but what you read on the net on any subject at all. Rick, how was the ag pilot business? The ATP rating? The stolen construction site plywood turned into a fine dinghy? The schooner trip to Mexico that lasted 5 years? The master of a an ocean going freighter for ten years? All before you turned 35? Yeah, sure Jax, you were looking at the GPS and read the COG but not the speed ...

The master of a an ocean going freighter for ten years? All before you turned 35? More typical Jax fantasy material ... The only thing you got right is the ATP. The rest must be some envious fantasy you have about some other guy. It looks like they let you out a bit early this time or they haven't got your meds quite right yet. The speedos a bit too tight maybe? Rick |

ricky, I know you don't understand this, but you do NOT navigate minute by
minute by minute by minute when you are well offshore outside the 100 fathom line and not another vessel in sight. "playing" is the right word for the situation. as for the rest, I see you have conveniently forgotten all that you posted while your were still "finding" your screen personna. on my gps at that time, speed was displayed on a different screen from course.

Ball is in your park, Jax. Show the posts. Put up or show yourself to be
what we all know you to be anyway, a jealous, impotent, incompetent wannabe with a vivid fantasy life who thinks a flamefest means someone cares. Have a nice day, Jax. You aren't worth the bandwidth.
