You are still full of BS otn.
LOL Of course I am, I'm a career seaman. The difference between us is, I
know when I'm BSing, but you have neither the experience or knowledge to
know when I am, else you'd know I never BS about navigation safety.
I make no suggestions not to use all
techniques...just that under many conditions all you got is the GPS.
..... and as just as many conditions, all you got is the "old"
methods..... i.e., it's a rare case when you can't make helpful use of the
natural conditions occurring around you, if you know what they are and how
to use them.
Survival at sea is probabilistic. If the Gods are on your case no amount
of deciphering the currents and wave shapes will save you.
Not always true .... often true, but not always.
You really think
you can detect a floating container when you can't see the bow?
You want to explain what that has to do with navigation? The discussion
is navigation, not collision/allision avoidance.
In most circumstance it is probably 80 or 90% GPS/chart...10 or 20% to
all of the other things you can do. In heavy weather and deep water it
is pretty close to 100% GPS.
Depending on the vessel and navigational equipment available, there's a
good chance that if you were in charge of a watch, for me, you would
change your ways real quick or find a new berth at the first port.
Under any circumstances the chart situation in some places is pretty sad.
For instance of the errors in the Pacific Coast of Mexico have been known
for many years...but we still await a fix. The purveyors deny
responsibilty shifting it to the charting agencies. The charting
agencies show no desire to fix the problems in our lifetime. Mostly Gov
at its worst.
G I can't disagree with any of this. However, from involvement in
creating a new chart, I do know that many cartographers are trying with
limited resources to correct and upgrade our charts, with results that
could indeed be better, but their failure has more to do with idiot
politicians, than dipsquat beauracrats.
And to risk a broach because you feel uneasy? Because the waves don't
look right? Becasue you think you hear something? Sometimes I think you
have never been to sea...the number of people who hear or see things at
night is well known. Had a Captain on one occassion deploy his anchor in
a 1000 fathoms because he could hear the freeway and knew we were about
to go aground. Sure he was extreme but virtually everyone has the
problem to some degree. It would take a very clear indicator before I
risked my boat against a GPS/Chart position.
LOL I think I said this once before ..... you must be a lawyer.
Go back and read what I said again. I said "if it's possible". You do what
is right for the conditions and vessel you are on .... and this MAY
involve risking a broach. YES, if the waves don't look right, you weigh
your options and proceed. YES, if you think you hear something you
shouldn't, you weigh your options and proceed ("proceed" may mean "stop").
One thing I've learned from reading your post.... you may know celestial,
you may know radar, you may have some deep sea time, etc..
BUT, the only thing you MAY be any GOOD at, is reading a GPS, and I'm not
too sure of that.
BG As to having been to sea ..... EG "I've wrung more salt water out
of my socks than you've ever floated on", to quote an old Bosn I knew.
otn
Actually I am by training and a long career an engineer. It is what
seperates us OTN...you react I go for understanding.
Sure your socks are soaked in salt...so perhaps is your brain. I think with
your long time frame at mis-understanding this stuff you are very well
qualifled for say Chief Officer on the Royal Majesty. He did a truly fine
job of successfully identifying the unidentifyable...as I am sure you would.
But he was really salty.
Wish you could have been on our little trip with the "freeway" Captain...you
could have helped him set the anchor.
I prefer to navigate around floating objects as well as fixed ones. If you
ignore the floaters I assure you something you would rather avoid is likely
to occur.
