Ping!!

Roy my first knowledge of sonar was gained from a picture in Encyclopaedia Brittanica of a submarine emitting a sonar beam to the sea bottom. The quiz author probably saw the same picture. 😀

SOund NAvigation and Ranging. I wonder where the downwards went?
Roy

@ Luckyduck. The format of the quiz is what we call a monkey puzzle. And it does seem to work. Because my monkey is very puzzled.

As far as I am aware the yachts I used to sail never had sonar, but they certainly had echo sounders - albeit that they use a similar principle. But sonar is certainly not what it is called in the UK. Is this a global naming confusion and it is called sonar in other parts of the world?

John Moses Browning did indeed invent an automatic gun in the 1890s, but about 5 years after Mr Maxim.
His was an improved version using gas pressure to reload, rather than the mechanical spring action of the Maxim gun.
Cheers, Doug 😎

I am definitely out of here now!
So many repeats now, mostly with the same 'dubious' 'correct' answers as the first time.
Always initiating the same debate. Seems like this Quiz has run it's course.
My personal average is 93% but Germany is rapidly sliding down the Chart, and about to drop off, since my colleague joined the fray; currently 70% with 13 wrong answers!☹️ Sabotage!
Ciao All, Doug😎
PS situation reminds me of my first job where I once overheard our finance director commenting ironically to a colleague-
"If things don't improve soon I'll have to ask you to stop helping me!"

So many Brownings??

How come Longstone lighthouse was not given as an option (Grace Darling is not it's correct name !

YES once again loosing % for getting a wrong☹️😠 RIGHT answer. THE CORRECT answer SHOULD HAVE BEEN the LONGSTONE Lighthouse, As EDW rightly says it's just a NICKNAME for the lighthouse given by Trinity House. 😠😠😠😠😠😠😠😠😠😠😠😠😠

Agree re Longstone and losing % points. Most irritating...

I agree with you Singingpug. If the question setter cannot be bothered to do the research in the first place what is the point. All of the % I have lost have been over questionable answers. I must admit I like doing the research to find the answers because it keeps the old grey matter ticking but we need better QC in the setting of the questions. No I am not volunteering. 😂

Longstone Lighthouse is the correct answer, Grace Darling was a famous keeper of the lighthouse so Grace Darling’s Lighthouse is a nickname. So much for AI.
🤔

Well I got it wrong. No surprise. I picked "B" because the actual answer was not there. Grace Darling Lighthouse is actually Longstone Lighthouse. I didn't know it had been renamed I just thought it had an association with Grace Darling the keepers daughter. It is an actual fact that Trinity House do not call it Grace Darling. They call it Grace Darlings home. It is not the name of the lighthouse. https://www.trinityhouse.co.uk/news/grace-darlings-lighthouse-home-reopened-to-visitors

Why wasn’t the Longstone Lighthouse one of the answers?

I decided on copper as not only used as previously mentioned but also copper bottomed hulls.
Hey ho, not going to lose any sleep 😴, it's been a long day-all work and no play in sight 😴

@Roy. We have 70 parties in our upcoming elections. Only two matters. The rest is just toilet freshener.

I suppose that in many ways Jumpugly you are blessed to have a choice of stores to use - many of us only have one choice, and often a good distance away.

Thank you Roy.
There is truly never a dull moment over here! 😉
I think my shock is based mostly in the fact that this sweet old man had pretty much turned into a snarling werewolf in front of me.
As you can imagine emotions run pretty high now. In the end, I don’t mind the extra drive distance for supplies; it’s a much more scenic route anyway. 😉

Hi Jump.... I would imagine there are many arguments going on re-P****cs in the USA. The problem could be solved if you had a 3rd. party to vote for.
I watch the election results for USA and everything is so close percentage wise. Both sides have a good size number of people to support them.

About a third of our electorate do not vote so it only needs 35% or so to give a party power to govern.

I do not envy having to vote in USA it is far too divisive etc. I suppose it is best to keep your own council and smile blandly.
These days it is so difficult for all of us to decide what is fact and what is f(r)iction, other countries intervene and elaborate on small truths to create an untruth.

But it does keep the rest of the 'free world' entertained.
Regards, in a non-political way.

Hi!
Concerning the question of 28 April:
None of the four answers are correct, because it is . . . .

the hammock! 🤣🤣🤣🤣🤣

See you again soon,
Michel-C. in Holiday mood

Not having that! Non ferrous metals were used long before iron, mainly due to the temperatures needed to reduce the ore. Copper was used for nails and rivets in ancient Egypt, copper has been found in Phonecian, Babylonian and Greek shipwrecks, and probably more besides...

That is a great shame mate as I get older I to sometimes get myself in trouble by saying something I maybe should not, my wife tells me I can be rude and abrupt be she is meek and mild natured but it is usually my sense of humour that gets me in the biggest trouble people just don't get it.
Sometimes things ruin your day and take all day to shake it of.i would it is his loss🤣
Philuk👍

After a hot streak, I have managed to stumble again the last two days.

However, I will blame it on a sad situation that happened to me last Thursday when I walked into one of my favorite old-time hobby shops and stumbled into a political meeting that that was taking place in the back repair section of shop. It was ugly and I was stunned at the vitriol and hate. For some reason the owner, who I like quite a bit, and four of his friends were mouthing off wildly to one another about this, that, and the other. It was a bad look and I started for the door. One of the owners friends made some stupid crack and that's when it got really ugly as I am not one to back down.
I yelled at the owner asking about what the hell was going on in his store, that it was a bad look, and bad for business. They all laughed and I asked one a-hole in particular if he wanted to step outside and sort it out. It almost came to blows. But, the owner interceded and told me it was best that I go.
I think for a second he was embarrassed that I walked in to see him and his like-minded friends together, but to save face he angrily showed me the door...like I was the problem.

I'll never go back. But, the whole situation left an awful taste in my mouth and deeply troubled. Such are some of the problems we have here stateside.
Now I'll have to drive an additional 15 miles for glue and strip wood from now on. Uggh...

Another correct answer I have say I got it because I get it wrong a lot,
Happy boating chaps
Philuk👍

I agree Rock!!

Copper was used be the Egyptians for fastenings in building their ships.

I think this should have been worded "What was the first metal used to build a ship" the correct answer would be "Iron" because it asking about the whole ship. However the way it is worded the could well be copper. Anyway I got it right 😀

These are the questions I like. No need to load the guessing finger.😃

Back onto safer ground 😊

Well I got this right the last time it was asked. I thought it was worded slightly different and they were trying to catch me out. So I chose B. Piloting is only used in restricted waters where you can see a landmark or other navigation point.⛵😊

Many years ago I started doing the Yachtmaster navigation course, never finished it though. Dead reckoning is when you know the time had a look at the compass for course direction have made and noted course changes and taken into account speed.
Otherwise lost!
GPS is so simple now that virtually all rely on it, even your mobile phone can cope.
Our son's yacht has automatic course control so no need to stand up on the helm, that is when I found out I get sea sick!
Roy

Personally thought it was "B". Oh well, guess I need to eat more bananas 🍌 😋

Could be B or C I went for C because of how I was trained.
AustinG

Repeated question; answer C again stated as correct. NOT!!

Do water wings qualify as a PFD?

I was taught that a protective firearm device was anything with more firepower than the opposition

Slowly making a comeback...5 in a row. Lucky for once. 😊

I've always called it a bouyancy aid...

Simple sailor, thank you for the detail, not what I expected!

This time it was "eny meany miny mo" or in plain English I guessed well best of two🤣🤣
Philuk👍

Well even with the pretty fancy dancing my points remain potentially freaking disasterous.

Doogle. Your suggestion is pfd. Pretty f dangerous!!😂

If one's personal floatation device does not work, it might be a good idea to have a preventative flooding device ⛵😂

If anyone is interested in how a ships log gets it data this site is interesting.
https://maritimesa.org/nautical-science-grade-12/2020/09/20/ships-log/

I think I may have to bow out of this Quiz.
If only to see how my new 'mit Quizzer' (ich weiß nicht wer!) fares.
Although my personal score is 90%, and has been for several days, since the last disastrous (for me🤔) sailing questions, the Germany score has dropped and dropped to 79% and 9th place.😭 I'm being sabotaged☹️ Never before has Germany recorded 8 wrong answers.
My worst was 5.
For the record I was correct today. OK I had an advantage having worked on many ship COMMS systems over a 40 year span. Including interfacing the Ship's Log to the radio systems.
Mind you, most ships these days rely on GPS to monitor speed and position - and then send the data to the Log recorder, equivalent of the 'Black Box' Flight Data Recorder on aircraft. Even the smallest boat can now be fitted with an inexpensive GPS receiver to do this.

Traditionally the LOG in nautical terms (or Logbook in earlier days) is simply a record of events in the operation of a ship; position, speed, arrivals departures, sightings, collisions, sinkings☹️😭 etc etc.
Cheers All, Doug😎

Hi Doogle and Boatshed,
Sorry to be a myth buster BUT ...
Transducer is simply a generic term for a device which changes (Transduces) one form of energy into another, or vice versa. They are useless by themselves, they are the start and end points of a processing system, input and output..
Classic everyday examples known to us all are the microphone and the loudspeaker.
The former changes sound pressure waves into electrical signals, the latter changes them back into audible sound pressure waves, but only after being processed by the amplifier in between which completes the system. As a matter of interest there is yet another 'transduction' before we can 'hear' the reconstructed sound - Our 'lugholes' transduce the sound waves into minute electrical signals which trigger neurons and 'tell' the brain what we have heard🤔

@ DOOGLE; The first example you mention is an Echo Sounder.
An Anemometer is always for measuring wind speed, don't ask me what an 'anemo' is coz I don't know, probably derived from some obscure old Greek word. It works in the same way that the ship's Log works. An impeller revolves according to the speed of the wind or water current striking it. Output can be analogue, a voltage generated by a small motor connected as a generator, or digital derived by counting revolutions using an optical gate generating a pulse train.
The transducer sends electrical signals to an amplifier and display/recording system.

@BOATSHED;, I don't know precisely what you fitted to your boats but there must have been some kind of display unit; voltmeter or screen depending on the type of transducer (analogue/digital) and processing system, inside the boat.

Hope I haven't discombobulated you🤔
Cheers All, Happy transducing, Doug😎

To me a boat transducer is in the hull normally pointing down and help to provide info on fish, depth etc. An anometer is normally a wind recorder.
AustinG😀

When I fitted one to two different boats that I owned they were known as Transducers. But some still called them Logs. I would have still called it a Transducer though, it's not that long ago that I sold one that I had in my garage that I still had as a spare one.

Morning Boat friends!
Yet another new word! Cool! I'm learning and learning . . .
Perfect as a landlubber!
When building my stern wheel steamer I need an altimeter rather than a log!
As always, three steps forward, one step back. I think I've set myself a real first-class challenge here. Like this word search . .
🤣🤣🤣🤣

Hmm... According to records Joshua Slocum did make stops, albeit only to resupply the Spray.
