I capsized many times when learning to sail and not once did it remain upright or self right. We always had to climb on the side and pull it upright, and as it rolled clamber inside. That is assuming upright means the mast is pointing toward the sky.

Not sure if I need this method of navigation when finding the position of my boat on the pond. 😁. I had to read the question about twenty times before it sunk in, or is it sank in ? Then I did a simple drawing 😁

Well I got that one right. Just so happened, some weeks ago I had been researching buoyancy while designing the motor barge. So I am still learning. 👍

Well I got that wrong. It's a long time since I did any dingy sailing but I thought I knew the answer. I always followed the wind shift. Maybe it is different in a larger boat. No idea. 😂🤣⛵👎

Hi Pat.
Don't leave the Model Boats Forum. There are only about 2% of the 1,858 members doing the QOD on a regular basis, so it's not an important part of the Forum.

Well I managed to guess this one correctly today. Only because of my IT back ground. I had come across the word Teredo as used in the phrase "Teredo tunnelling" so putting two and two together with Navalis which looks like Navy I guessed correctly.

Hi. After my exploits with the Hybrid Barge hull design I have now started work on a powered barge. This will be using a Kort nozzle. Pictures show how far I am down the road. It is now on version 6. I keep looking at it and then changing things. I think this will be the final version. It's almost ready for printing.
I have finished testing Kort nozzles and propellers and will at some point post the results on the Kort nozzle blog.
My printer has started to do silly things. Like going into thermal runaway on the hot end. The other day it was getting ready to print at 210°C, then I could smell hot plastic and looked up to see it at 270°C and rising. I have changed the hot end, thinking it might be the thermistor temperature sensor but it still does it. It is only intermittent and I am starting to think the MOSFET that controls the power to the hot end by PWM is breaking down. So it will be mother board out and do some tests.
I have spent most of this week getting over Covid and fixing a 150 Watt powered sound mixer. That was interesting. I managed to get the schematic from the Australian manufacturer, which helped in tracing the faults. All working now and going back to my musician friend 😀.

Dear RNinMunich.
My comment was a light hearted one, hence me saying "Only if you are a politician can you get away with such things". British sense of humour.😁.
I still think it is wrong to change the question. Not just because I got it right, but because I couldn't see anything wrong with it.

I answered todays question correctly about the Fog Horn and went to 97%. After looking through the Trending section I returned to the QOD and the question had changed and I had dropped down to 93%.

That looks much better than the one I made using the same motor. I have an open blade mini saw bench which runs off a Lipo battery. Works well but little dangerous. 😁 I have just down loaded the files. I will add it to my list of things to make.. Plus I think a mini sliding mitre saw would be handy..

Hi. I agree with all of the sentiments model shops are having a tough time. I have a list of shops that are still going but I must confess to going to the great river shop more times than I should. One of the problems with the local shops is they cannot afford to advertise. I would hate to think how much an advert in a good hobbies magazine cost per page now days. Years ago I used to pay £1,000 a month per page to advertise a mail-order PC company and were advertising in three magazines. Here in the UK one guy has at least taken up the batten and is trying to promote model shops on his YouTube channel. Maybe that is the way to go.

Hi Alessandro. Thanks for the explanation but I fully understood the question. It refers not just liquid but also granular. As in the question saying "often in liquid or granular form" Hence my comment....It's just the Ai trying to get to grips with the full understanding of the English language, it still can't phrase a question correctly... One day it will get there.

Strange question this one.
I am sure we had the same question a few weeks ago and the answer was "Liquefaction". As it happens I guessed right because it seemed the only sensible answer.

Hi. For what it's worth here is my take on the "Question of The Day" and cheating.
It is a question and not an "Exam of The Day". If it were an exam I surely would not look up stuff on the internet. However I would expect the questions to be confined to what I was educated on or had considerable knowledge of. As it is a question I see no harm in looking up a possible answer on the internet or in one of those things called books. From my experience you rarely find the actual answer, you still have to use your brain to get there. I would not consider it cheating more an education. I have learned an awful lot from QOD. If someone asks me a question, and I do not know the answer I will probably say, "I don't know but I will try and find out for you".

Well once more, just as I was getting rid of my RED mark when I guessed the wrong answer. Back to another 30 days of waiting. 🤣
I am not sure that the answer fits the question. Surely it is not of "tactical significance" but of just of "significance" If it was tactical they wouldn't choose the leeward side they would go for the windward or weather gage.

Hi Tim.
Looks good. I was looking at a 3D printed sub at a model boat show. It was being sold by a small company for about £90 (?) and to be honest it wasn't any better than yours or as long. I have never tried ABS because as I understand it, you need a well ventilated room due to the noxious fumes etc.. After trying many filaments, I have fallen in love with ELEGOO Rapid PLA+. Like you I am in my 70's (73) and love trying new things. Anything to do with engineering keeps me happy 😁

Hi Nick. I have a cheap pen on order. Going to give it a try. It's not for all joints, just where a fillet weld could go. Will post the outcome when the pen eventually arrives from China.. 😁

Hi All. On the subject of 3D printing and joining parts. Has anyone used a 3D Pen like a welder for doing joints etc.. I was going to buy a 3D Pen to try but thought I would ask first.

Hi Alessandro, and other interested members. The pictures show my quick run off for the powered barge bridge. You can clearly see when zoomed in that there are layer lines and vertical aberrations. However I was testing the part to see if I could print without any supports for things like the window frames and over hangs and in one go. So no gluing.
It came out very well and only took about 45 minutes to print. The lines will always be there but can be reduced by further fine tuning. I maybe need to go through the printer resonance check again. It uses an accelerometer to test the resonant frequencies of the printer frame and then compensates. That should clear up the vertical problems. The lines are very fine and once two or three coats of paint are applied and sanded between coats, then can hardly be seen, if at all.
Once I find a good setting in my slicer (Cura) I save it as a profile then I can come straight back to it if I need to. The bridge is designed with 0.8mm thick walls and roof. I have found that when designing things in CAD it is good to have a knowledge of the printers capabilities rather than just go and design a wall to be 1mm thick I would make it multiples of 0.4mm. Then I know when I print, the slicer will use that many walls or layers. The printer has a 0.4mm nozzle. I sometimes set the wall thickness for 0.38mm. The software driving the printer is called Klipper and I must say it made a massive difference to the quality of print. A lot of printers now use Klipper as the core software.
Most of the 3D printers are FDM printers (Fused Deposition Modelling) I do not want to get into SLA (Stereolithography) as they are very messy but great for very fine detail.
Here is a good manufactures description of the different types of 3D printing.

Well I missed out on this one considering I have just done a build on my 3D printed hybrid barge hull I do like ScouterChil's comment from two days ago "correct sizes -things such as tires, bollocks, life rings and such." It would be interesting to see what 3D printed bollocks look like 😂. As for me I love CAD and 3D printing. I use a Creality Ender-5 S1 and FreeCad for modelling & Cura slicer. I will be getting a laser cutter in the future but when all said and done they are only tools. When I was working in R&D some years ago we had to design protypes using a drawing board and old fashioned modelling techniques. When CAD came along to our company my prayers were answered. From design to product was way faster. I retired just as 3D SLA was taking off and the first thing I did was by a 3D printer kit. It ended up looking like something from the Munster's house by the time I had finished making mods to it but I learned a lot about 3D printing. I have my Ender producing very smooth prints. However my brother has just bought a Bamboo labs printer and I would never believe anyone could produce an out of the box 3D printer that worked out of the box. But it did and with no knowledge whatsoever he is printing some amazing stuff and in different colours (Colors for US friends) Just to finish up. I get as much fun making things out of wood and plastic card.

Hi All. On the "RT" question which I got right by guess work. Like most of you I cannot find any reference to "RT" on any chart info except the Canadian & USA charts where it means "Radio Telephone Station". I agree with others suggestions that anyone getting it wrong should be awarded a free "got it right card" "DW" is more like the correct answer. This link might be handy to some people.
