Re: Is radar like the extinct typewriter?

Thanks Adelie........but why did you not post that about 200 posts ago?

It would have saved us a lot of explaining....

Because I thought the implied questions were probably what the OP was really interested in.

Once I figured out he was a bit of a troll it was less about answering the implied questions and more about having fun with the thread.

Rather than the implied question I will answer the plain text question.

No radar is not like the extinct typewriter. The typewriter was supplanted by computer and print because it did most of the jobs a typewriter did only better. It was easier to edit the final product, it was easier to fill in boilerplate, it was easier to create multiple versions of the same document, multiple fonts and sizes can be used in a single document, tables and graphs can be inserted.

The advantages of typewriters included lower cost to purchase and maintain and the ability to operate without a power supply.

One of the typewriters last adantages to be lost was filling in forms. This was only lost once internet access had approached saturation. Until then people without Internet had to be able to neatly fill in forms they'd picked up, such as government forms and job applications. The last typewriter factory closed 5yr ago. There was still a market but not big enough to support a production line.

Typewriters did one thing, put letters an a page and computer/printers did that, with more sizes and fonts plus they do other things like tables and graphics.

Radar does a number things: detects weather, detects land formations, detects other vessels, detects bouys and other objects all in the actual relative locations and announces your position to others operating radar in the same band.

The best weather forecast can't warn you that a squal will hit in 3min. It can't show you the way around the squal that is 10-15min away.

AIS can't show you a vessel that isn't transmitting.

GPS and a chart plotter can't tell you here you actually are relative to a landmark that was incorrectly mapped. It can show you misleading info about about that dragged its anchor and now is in the channel rather than next to it.

Other instrument now do some of the functions only radar could and do them better, indicate time and PCA for a passing vessel.

Nothing will replace some of the functions of radar so it is likely radar will be around a long time.

That said it may not be something you want or particularly need.
I nominate this for best post of the thread! Superb.

r particularly need.
Excellent post and I don't think one person disagreed with it.

Radar looks like it has a long life ahead of it, even if it's not needed on every cruising boat.

I enjoyed your post... however, I would maintain a radar does one, well maybe two, things. It spits out a microwave and reads the reflected waves that are bounced back. All the ways we use that information are the product of our imaginations. Sort of like a typewriter can be used to write novels, scientific documents, biographies, poetry, manuals, ransom notes,...

Well if you want to look at it that way then what a radar does is three things:
A. Directionally emits microwaves
B. Detects microwaves while noting angular info of received signal
C. Displays information from returned signals showing angle and distance
D. Some radars now have various features that aid improved interpretation of signals

A typewriter pounds ink onto paper in specific shapes in specific orientations and spacing.

A computer similarly applies ink to paper but with more flexibility in shapes, orientation and spacing and generally with greater ease of use.

Ah, so that's why all the radar factories have closed down and they are removing the radars from all the ships... I was wondering about that........

With the new stealth ships radar won't detect them anyway. It's just another gadget for people looking for an excuse not to go yet. I guess some people need all the help they can get though.

GPS gives an accurate position. Chart plotter is less expensive, more useful, and less power hungry. Radar doesn't work as well in fog and poor weather when it is needed most. The odds of hitting another boat in the dark, fog, or bad weather is slim to none. If you feel you need one anyway to calm your anxieties, by all means go get one.

Re: Is radar like the extinct typewriter?

My computer still has a QWERTY keyboard. It would seem radar is developing somewhat in the same manner. Still serving the initial task and then some.
Monitors and antennas are getting smaller and discrimination is getting better. You don't even have to worry about getting cooked with the new ones.

Hmmm..... "Radar doesn't work as well in fog and poor weather when it's needed most.".

Seems to me like you have everything twisted up bassackwards, so it's a good think you tuned into this thread for some more accurate information regarding radar.

That is exactly when radar is at its best.
