I knew the anchors in B C and D so guessed A 🤔

That was a hard one, had to look up the types of anchor first

Pat! I seem to remember you were complaining about the 100% scores and now you are at 97%!!!!!!🤔🤔🤔🤔
Roy

Seems a lot of the old timers are no longer bothering to answer - I wonder if this is because of the repeat questions or are people just getting fed up with the QoD ?

Ah, th'old "bulbous bow" ploy....

The revision questions are working, 100% so far on todays question
🤣

As of today, how many of the participants in today's question are still unaware of the existence and function of a bulbous bow?
AI is keen for this number to approach zero, hahaha.
It wants everyone to understand the concept.

Shortest route and longest answer 😂

We'd already talked about it, not in the AI ​​question of the day, but when we asked the questions of the day.
The question posed was the difference between a great circle [ortodromia] and a rhumb line [lossodromia].
Then I think the AI ​​also touched on the topic.
However, it's true that a route like the one described in today's question, on a map using the Mercator projection, might appear to be the longest route.

Thank you for correcting the problem, Happy Valentines Day😊

Small glitch. Now fixed 👍

I answered correctly and the site showed 100% on keel.
Weird

Same here Ed

Todays question has got an issue, I answered keel and was told that it was correct but still got marked as wrong.

Ron,
I have made a donation. Answered D) Keel, and still had it counted wrong.
So, no, you are not being penalized for not making a donation.
Dave

Is it a problem with the adds to make a donation. Do you have to make a donation to have the correct answer be counted as correct. Maybe some of the advertising is corrupt and causing problems🤔

Same here, answered keel marked as wrong

This website has a bug, is there a support person to look at the issue and fix it? 👎
I answered the question correctly as KEEL and it marked it as a wrong answer.

It highlights keel as the right answer, which I choose, but marked my score as wrong???AI should go back to school 🤣🤣

I put keel and it said i was wrong😠

I wonder which of the wrong answers you have to pick to get a Green dash ????🤔🤔🤔🤔🤔🤔 If my red line turns green, I might have this post redacted 😀😁😁😀.

What is wrong with the game, did the correct answer and did not show tha I did the correct answer says that it was incorrect. Just asking for donations. Is this a scam or what. Love doing this game and looking what is on the forum. There are other forums out there, will give it until Monday and if not corrected I am done🤔

Hi Pat, I also put "Keel" as it is such a easy answer to anyone that builds model boats and I also have a red mark !!!!!😠😠😠.
The only thing that I did differently this time, was to have only just answered the 13th Feb question and then I reloaded the page again 10 minutes later for the new question-- but I got no confetti. That I couldn't understand. Then when I scrolled down the page and saw my red mark!!!!!!!!!🤣🤣🤣🤣☹️😭.
Such a easy one to get correct, and if I had got this wrong I think that I would go out and sink my keel-less boats 😁😁.
Strange because the Keel answer has 100% correct answers at this time ??? 12.29 am.

AI playing up again - answered today’s question- got it right - the confetti fell but the table at the bottom the number of incorrect answer went up by one !!!

Yes I was wondering about that. On this forum it is about the slowest rate I have noticed. I have used CCleaner to get shot of rubbish and that really does work, but it does strip the data which you can protect to some extent.
I paid £13p.a. but it was worth it, although it is almost 'start again' afterwards.
Roy

Has anyone noticed the page load speed is slow again.?

Geography ?
🤔

Hi, LuckyDuck I'm sure that somebody can tell you where you can put the second answer-----🤗
- I could tell you but then I would probably get banned off the site...🙄🙄🙄😁😁😁😁😁😁!!! ( A rather rude joke ).
No- really the second part to the question was irrelevant, just an AI glitch I believe 🤔🤔.

Helloouu and Good Morning Friends,
Translating from English into German can sometimes be challenging. That's just how it is when you learn English as your fourth language.
As a landlubber, I have to read twice to understand what is meant!
As I said, you never stop learning, even as a grandfather!
🤣🤣🤣 😉😉😉
Your Michel-C.

Its the double questions with a single answer that is confusing - is there another place for the second answer???????🤔🤔🤔🤔🤔

Another revision question - don’t seem to be getting many new ones at the moment

Yes thats the conclusion i came second part of question erevelent .
Spelling probably wrong🤣🤣
Philuk👍

Oh, okay, I get what you meant, thanks SimpleSailor.
Well, the second question is completely irrelevant. Even if you know it, you can't answer because the options are related to the first.

Hi Alessandro.
I notice Phil could see the split question. The question asks the following Q1: " which of the following sails is set immediately above the main course on the mainmast" Q2 "what is its historical significance in sail handling during long ocean passages?" 😂

Yes i saw the same and wondered about it but opted for sail name
Philuk👍

I noticed the split question, second part was about historical context or something....

Sorry, Simple Sailor, I don't understand what you mean by a split question.
This seemed like a typical question from Pat, who knows all the sails inside out.

Well apparently I got the question wrong. Never mind just another 30 days to go. Just out of interest not a complaint, The question is in two parts but I only see one answer. 🤔

Yes, Alessandro I would have said that if I could have got on here earlier 😉- We have now had this one 3 times that I know about.
I have had to come on the site using my PC as I cannot get on with my phone as I had the opportunity to delete a load of browser history and I have yet to figure out how to get back onto the forum with my handy phone ??? 😠
What,s happened with Doug (RN in Munich ) he hasn,t been on QOTD for ages 🤔🤔 has he lost interest or is he not well.

Okay, I'll say it. I was waiting for someone to say it. Yes, it's a question the AI ​​has already asked, it's a repetition.

Nick and anyone else interested in the answer.
The propeller grips the shallowest part like a car wheel (which turns and moves it forward) because the deeper you go, the denser the water becomes.
In fact, the different densities of the water at different depths are the crux of the matter.
It may seem strange, but that small difference (between the layer hit at the top and the layer hit at the bottom by the blades) acts as a grip. The effect is sufficient to be appreciated.
I hope I've been clear.

I've never heard the term "helm bias", but C was the only logical answer
(based on personal boating experience).
Score one for lucky (logical) guesses!
Dave B

Thanks so much for the explanation Roy.

Oh, I forgot, Nick. I'm referring to real boats, as I think the question of the day referred to. For scale models, even though the physical principles are the same, the scale factor changes many of the forces at play.

Hi Alessandro, In UK we mainly have side wheel paddles. The word propwalk was there before wheels were driven as in cars, so propwalk was appropriate at the time and there it is stuck!
Roy

Hi Nick, you're close, but it's not quite true.
The propeller (in its lateral movement) doesn't behave like a paddle wheel, but rather like a car wheel.
Paddle wheels (like those on boats on the Mississippi, for example) aren't completely immersed in water, so they're like oars; they push the water backward and move the car forward.
The propeller can't do this because it's completely immersed in water.
To put it simply, the concept is more comparable to a car wheel. If that's what you meant, then sorry, I misunderstood. But the question remains: why should a propeller behave like a car wheel?
The spinning wheel grips the ground and therefore moves the car.
Where does the propeller grip?

Not far behind you Roy! Only 10 years..

Basically, the prop acts like a paddle wheel,, a certain amount of the thrust is to one side due to the shape of the propellor Pitch would add to the equation, coarse pitch would produce more "side" thrust than a finely pitched example. There is probably a mathematical formula involved in there somewhere, but I ain't no mathemetician..

As far as models go you have to balance between small high speed props, (extra wear on bearings and u/j's) and efficient larger props that 'prop walk' but are quiet with it!

I always enjoy working out a drive train with my smaller models and have been working with 4/5ths Sub-C 2800 maHrs cells. Slightly smaller battery than usual type and of course less weight. I also use Aliexpress tiny esc's and there are lots of small motors available. All the above to accomodate getting old and accounting for what you can carry.

Keep on carrying on for the 80 old members still doing what we started 60 years ago!
Roy

Propwalk!
