Oh dear I am not doing very well on some of these questions - just goes to show we can not be an expert in everything - does stop the old grey cell from dying off though 😁😁😁😁😁

This is a rehash of a question we had a few months ago!
'Let the light shine on'😁
😎

Take a look at the dashes below your name, there are 30 of them. Each red one pushes you down the list until you reach the level matching your red count. Four example if you had only green dashes, IE all answers correct, if you got todays question wrong you would drop a position and it would take 30 days to get to all green again, if you got every one correct. If you have unanswered questions, this will drop your position but as soon as they are answered your position will reflect this.

WOW!!!!
I have done it.
I am ⛵⛵⛵⛵⛵⛵⛵
S A I L I N G,
10 in a row and I have jumped up a notch.
I have gone up to 8 on the list.
But is it because I am sitting up watching the telly.
The Secrets ofthe London Underground.
And I have been and answered it earlier than someone else and got an earlier spot on the % list ????
It makes me think like that this early now I have jumped up a bit on the list.🤔🤔🤔🤔⛵⛵⛵⛵.

Lucky you Boatshed - I am going up and down like a yoyo LOL

Well this makes no sense.
Nine questions in a row correct.
Yesterday I was at 8 on the list.
Today I am now 9 questions correct in a row. and I have now dropped down to 9 on the list.
I dropped a placing on the listing???
Crazzyy 👎👎👎👎👎😮😮😮🤕🤕
I willnever get this way of how this is being worked out.🤣🤣🤣🤣🤣🤣🤣
Well at least I have had a good run at getting some questions correct.
I just hope I can make a double figure tomorrow on correct answers, and then I may just get to make a double figure on the LISTING as well ??????🤣🤣🤣🤣🤣.
Then in the words of a true ledgend (Sir Rod Stewart) I am ⛵⛵⛵Sailing. Hopefully

Funny I was reading up about keels when I was designing the Hybrid Barge. So I thought I would get this one right. But NO. Again I should have read the question twice before I answered, rather than just click, because I thought I knew the answer. If I had read it more carefully I would have chosen correctly. The key words being "commonly used" 😁

Well I an now 8 in a row.
I cannot beleive it.
I must be heading for a fall soon.
I normally go two or three then get one wrong.
Who knows what tomorrow will bring??

I’m close to the top but I’m scared of heights so a crash is imminent. 🤣

Actually a Becker Shilling rudder. A brief search produced this...

So is it TD👍😊

😎

I think the more common name for such is a Becker rudder.

Well got that one wrong

Alessandro - I am chasing you to knock you off your purch lol

All this diving is dodgy as far as I am concerned. I am a humble snorkel 'diver'.

My son has blackmail quality footage of me swimming as seen from below. But have seen some excellent sites including the Great Barrier Reef for a whole day. Then in the Andaman Sea off Phucket , where the water is so warm you hardly notice it.

Swimming with fishes at head level waist level and around your feet, definitely one to tick off on the Bucket list.

I had my own 'man' in a dinghy looking after me, mainly because he had to bodily haul me back into the dinghy afterwards. Good fun.

nice memories
Roy

I quite often wake up the bends. Mainly my knees they just object to bending too low. Maybe it should be called 'the straights', that is often the case too.

Up early today croisant and coffee. We had a 'break in' yesterday! Turns out a magpie also likes croisants.
Another day in the sun so will be in my shed from 07:15 hrs. Mainly tidying up. I used to build model boats in there but more of a maintenance shed now.
Roy

Greetings to all participants in the question of the day.
I don't want to spoil the fun of the game by inadvertently giving suggestions for the answer.
I'll just say that the question of the day is very easy for those who have done scuba diving (Ara, Aro or other).
Even those who have only done the basic course and even those with very little experience must know the answer perfectly.
One of the main problems for those who dive with tanks is the inert gas, that is, nitrogen.
It is not "consumed" like oxygen so it becomes a serious problem to manage in pressure changes [Boyle-Mariotte].
In freediving, however, it does not represent a problem.

With all this regulation reading and navigational aids I am thinking of taking a master mariners certificate as with all this new learning might as well use it.😊😊😊😊
However I still have to find out why 2 of my boats leak now!🤔🤔.
"Thinks" There could be a common factor here! "Me" and alleged competence. I shall go for the 'up the prop tube' possibility.

Got to cook Sunday lunch first, maybe I will try the exms for 2nd. Chef first.
Roy

Don't worry Boatshed, I am still paying the penalty of taking a holiday and being away from a computer - not even back over 50%, even with a string of right answers. Luckily, sailing questions play right into my past, so I can get most right. But for other advanced topics, it is pure chance.

My comeback has begun, albeit slowly.
😉

Wow that's a real stroke of luck. I dont know anything about sailing.
I have guessed this one right.🤞
I am now 4 days in a row of correct answers.
Just luck. 🤞
I just cannot seem to get any higher on the list.
Since it has been shown like this I am sinking lower.
I used to be quite a bit higher on the %.
I am not bothered anymore about how it it worked out as when it is tried to be explained it never makes sense to me so why worry about it.
It's just a bit of fun.
The ont thing I don't think should make a difference is, when we cannot get onto our computer for the day or so why shoud whe have to drop down ??Please do not go into explaining it as I am not bothered because it just goes iver my head.
Toooo much there that I do NOT understand.🤔🤔🤔🤔🤕👎

Up one today let’s see how long I stay there

Well up this morning and down again now I am getting dizzy lol

My variable deadrise deep V hull went very well yesterday, now need to find out where this deep V variable deadrise hull leaks water.
Roy

Hello everyone.
As for today's question, the answer was easy. It was more complicated for me to find the correct term in English.
In Italian it is called nodo "bandiera" which translates to "flag". However, since the description was clear, I understood what it was and then I recognized it in a photo (which showed the correct English nomenclature).
The strange thing (I don't know if the same thing happens in your country) is that the same knots in seamanship have one name and in the mountains (mountaineering/climbing) they have another.

Pertinent and interesting question.
In fact, many knots are also very useful for naval modeling.

My favourite knots to tie are a monkeys fist and a Turks head

Reply to Ross's message 4333.

Ross, that's the crux of the matter.
But I'm asking you, native English speakers. I interpreted (based on a translation that is anything but certain) that the anchor was on the seabed and had to be pulled up.
Perhaps this also helped me to give the right answer.

In the case of a reverse interpretation (i.e. the anchor is still on board and is about to be lowered) those who want to defend AI at all costs could argue this:
At the moment the anchor is lowered into the water, it is good practice to stop all momentum. At that moment we are effectively in a non-navigational condition.
Extreme sophistry.

I think instead that (if you British, American, Canadian, Australian, New Zealanders are inclined towards the second interpretation) the question of the day should rightly be cancelled (based on the new rules adopted by Fireboat).

I have always, well since I was shown how, liked doing Whipping. Many years back I introduced our son then 15 years old to a RYA course on basic sailing and some knots were covered but Whipping and splicing rope appealed to me.
I like to do the whipping on my model sailing boats where appropriate.

At home, my wife being a Woman Supremisist, commented on my little talent and asked what use it was? I had some cord by me and got out the potato peeler and cut the string binding away from the handle and metal part.
Apart from the look she gave me I demonstrated the art of whipping. I thought now she will have to use something I put together! Not quite what happened as she bought another one which is why we have 2 potato peelers now!😆😆😆

Roy

That has been a Knotical trip of nostalgia. Looks like we all got it right.
Good question.
Roy

The order was given “Ease to the Stopper”

While sailing it can be used for rigging a stopper to relieve the tension on a sheet so that jammed tackle can be cleared. I learned ropework at HMS Raleigh seamanship school and I always struggled with the rolling hitch..

A typical use of a rolling hitch that I have used many times is to take the stain on a halyard whilst the pulling force either by a winch or by people is eased to secure the rope around a belaying pin, commonly called a stopper

A rolling hitch if for attaching a rope to a pole or another rope for pulling it parallel and in one direction. A clove hitch is for pulling away from the pole at Plus Minus 90 degrees

Rolling hitch has many applications in ship rigging...

Surely you would do a rolling hitch on something solid like a tree truck, and you 'roll' it to ensure it locks from the direction of pull? It helps to have been in the boy scouts in the 'old days' when they used to spend half their time learning and doing knots.

I agree with Nick a Rolling Hitch would be a better choice

The ones that I stall on are rolling hitches, rolling hitch to the left or rolling hitch to the right. They act like a sort of one way clutch..

Lumberjacks use the sheet bend.
😉

Knowing a little about knots the other 3 rule themselves out my trouble is a bit of forgetfulness and I have to rehearse a half hitch beforehand every time I go sailing.

I like the bowline and the story of the rabbit that goes with it!
Roy

I learned all these knots in the Boy Scouts which is nearly 60 years ago and I can still tie them all. A few years back I donated the badges that I still had to my old scout troop in South Africa. They invited me to visit them if I was ever out in South Africa. I managed to go round when I was there a few months back.

I think the main point is it the vessel is not under control or command

so does this whole question pivot on the point Austin brought up

Drifting CAN be underway, but is not necessarily underway

Therefore drifting is wrong answer?

I believe the expression "to weigh anchor" is to haul the anchor up from below. To let go the anchor is to let it drop, ie it is still on the ship.

But the phrase used to say why "A" is wrong also says the ship is underway! Which as a question with options does not make sense.
Roy

But anchor ready to let go

I'm in need of a little enlightenment. As Alessandro points out, this is the critical phrase. "to let go" from the bottom or from the vessel. Can anyone one with a few more decades on the water than me explain "to let go"? From the seabed? From the vessel itself?

Would one actually know if the anchor is about to let go of the seabed, before it actually occurs?

If it refers to achored to the seabed then, yes, Alessandro is correct

I hope I can make myself understood as well as possible, ship modeler friends.
If not, it's my fault and not yours.
I start from the awareness that I'm not sure I translated the term correctly: "'underway'".

Although the letter D is not the best of a correct definition (I fully agree on this point) and could have been formulated better, it is the most correct of the four.

In any case, the dispute started by RossM is not so much questioning the answer D, but rather arguing that the answer A can also be considered correct.
RossM said: "Can someone explain why A is wrong? "
If I understood correctly, this is also supported by other people.
At the moment, 8% of participants support the letter A as correct.

Let's leave aside the common sense (or cunning if you like) that would have suggested (pragmatically) to choose between the two the least bad, that is, D, and let's dress up (for fun) in a regulatory and so to speak legal guise.
Let's quickly consider answer D first and then dwell a little more on answer A.
"A vessel not at anchor, not made fast to the shore, and not aground."
It is reasonable to think that it is in motion.
It is assumed; because there is a chance (although small) in the absence of wind and current that the ship is stationary even without being anchored or aground. Sophism.
This is why we would have preferred another definition.
What matters is the movement with respect to the seabed, but not any movement. The movement that a ship makes around its anchor, or its anchors (however large) is not considered navigation.
By headway we mean the inertial motion of a vessel, or its tendency to continue the movement even after the force that generated it (e.g. engine or sail) has ceased.
If a ship, even though its engine has turned off, is still gliding through the water, it is said to have headway. In this case, it must continue to comply with navigation rules, even if it is not receiving active thrust.

Actual navigation (be it under motor or sail) and the headway (fresh way, headway, sternway,) should be considered the same (in some respects).
The letter D is a terrible definition but at least it wasn't obviously incorrect.

Now, why is the letter A incorrect in my opinion?
" A vessel drifting with engines stopped but anchor ready to let go."
If it were only drifting it would be reasonable to think that the Colreg considers it to be underway (headway), therefore the relevant signals would apply (navigation lights at night and daytime signals during the day).
But that is not the case.
The answer is completed by writing that: "but anchor ready to let go".
If I translated correctly (correct me if I'm wrong because this is the key point) the anchor was ready to be removed but was still there.
Attention, there is no indication that the anchor was not making a head and was ploughing.
I must assume that the boat is making its movement (due to wind, current, wave motion or all together) around its anchor. The anchor is still holding.
Well gentlemen this is not considered navigation or making way.
In this specific case therefore I would use the signals of a ship at anchor (not in motion)
A is wrong.

For the purposes of Colreg, at night, in situation A, I have the navigation lights (right green light and left red light off, white sternlight) off but ready to be turned on as soon as the anchor is lifted.
The masthead light (or the two masthead lights if the length of 50 meters is exceeded) will be turned on if the ship is under engine and sailing under engine (if it is under sail).
In situation A, at night, I only turn on the white anchor light, 360 degrees of visibility) one or two depending on the length of the ship.
This solution (white anchor lights, 360 degrees of visibility) is common to situations A, B and C.
I have omitted the distinction for ships under twenty, 12 and 7 meters to simplify the discussion (and because it is not relevant in this context)

For the purposes of Colreg, however, I turn on the navigation lights (right green light and left red light, white sternlight) and the masthead light only in situation D (I repeat only in situation D).

So to recap:

if you want to cancel the question of the day because answer D is inadequate and imprecise (I would have formulated an answer that left no room for doubt) you have my support and approval.
However, the question said "... best describes when a vessel is considered 'underway' for the purposes of navigation lights and sound signals".
So I interpret it: "give an answer that is better than the others" and the others are certainly wrong.

If instead you consider answer A to be correct, in my opinion, you are wrong.

P.S.
Whether the engine is off or on matters for Colreg.
It does not matter in this question, it is true, but in general it is relevant.
Let me give you an example:
A sailing boat that is sailing under engine power must signal it.
The way signals are typical and symptomatic of movement, not of the engine.
A sailing boat that signals that it is proceeding under engine power (on and in gear) loses the right of way over motorized vessels.
For the purposes of precedence, it is also considered a motor vehicle.

Good evening to all ship modelers and sailors.

In my opinion the correct answer is D.
I'm only saying this because you've already written it in the comments (I usually wait so as not to ruin the game for those who haven't answered yet).

I'll tell you the reason and explanations in the next message (I have to be careful with the translation).
Of course it will only be my opinion, take it for what it is.

Then I would like to make some clarifications on the ignition of the engine.
Perhaps some statements have been made that are not entirely accurate.

In any case, COLREG is accessible to everyone and is the same everywhere.

Finally figured one out. Thanks Dad.

😀

Does the question then become:

If it is adrift is it underway?

Adrift CAN be underway, but isn't necessarily underway. (any sea lawyers out there??)

If it was adrift I certainly would want to see and hear lights and horn

answer A say its adrift. That is not underway.

That's the way I read it too, Roy.

So A and D are UNDERWAY, thus requiring navigation lights and horns, therefore 2 answers are correct?
