Clyde harbour tug "ARRAN"
I decided to renovate a very old model tug which belonged to my Dad. This has been in the family for over 80 years and was in need of some TLC. It is now fully radio controlled and runs from 2 x 18650-2000mAh batteries. Length: 41cm, Beam:11cm, Draft: 6cm, weight: 1.5Kg.

Fairey "Maybe"
I have just been fixing this boat up. It was built in about 1962 by my dad from his own plans. Made from Balsa wood with the bow carved from a block. All the bits were cut on my mums bread board and the boat was assembled on the dinning room table and always caused a ruckus when it had to be removed for dinner. It started life with a 2.5cc marine IC and made a real mess of the bath tub when dad was testing it. Now it has an Aquastar 4084 x 620kv brushless motor in it and 90 Amp ESC. I have the same motor in my Perkasa. The design is based on the Fairey boats and I remember dad always wanted one of the kits but couldn't afford one, so as all good engineers he decided to make his own. It's a bit broad in the beam but it moves through water very well. Just been on sea trials and looks good on the water https://www.youtube.com/watch?v=GEcliS_NH-Q

Powered Hopper Barge
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 210ยฐC, then I could smell hot plastic and looked up to see it at 270ยฐC 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 .

What a cock up. I was looking at the prop walk part of the answer and not paying attention the word "bow" when I chose the answer. Of course the stern goes to port.โน๏ธ

Hi. Can someone tell me if having the Bronze subscription would allow me to go back and answer unanswered questions or at least see what they were? Also by paying for year upfront it looks like you get a 2 month discount. Is that correct?

Well once again I have been hit by the system thinking I didn't answer yesterdays question (26th). I most certainly did and got it right. It was the longest answer. Do I have to start taking screen shots again just to prove I answered it??? Can anyone check the back end logs?

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?" ๐

todays question was a stinker. I kept looking thinking I should click on what seemed obvious, but then kept thinking, this a trap ๐ so I chose as a wild guess Nickel Ore. Bingo. I have since done some research and realised the Ai is getting sneaky and trying to lead us into a fall sense of security by mentioning 2016 IMSBC in one of the answers. It is a category C item in the 2016. I think it has been upgraded to A in the latest version 2024/25

Hi Lew
I had to replace one of mine. I purchased the switch from Amazon and replaced it on the small attached PCB. A bit of care is required so that the PCB tracks are not damaged. The actual assembly is made by Flysky so would only be available from them.

Now that is interesting. There are two correct answers here. Tidal flows do change direction at headlands C. and they do accelerate at headlands B. I just happened to pick the wrong one. Never mind. I guess I should have Googled it first. ๐

I was one of them that chose the Sterling Engine because I thought there were to few nuclear subs and way more normal subs, plus it was a way too easy and obvious answer. However after I got it right. I was surprised, so I did some research and came across this.

Hi Doug. As per Alessandro's reply. You can only look back if you subscribe or give a one off donation. I have given one off donations and you can't go back so I think maybe I did not understand the donation aspect or the system is not working. Does anyone know how many people subscribe ? If we all paid the minimum it would be ยฃ2.50 x 1,805 = ยฃ4,512.50 a month or ยฃ54,150.00 a year. I would probably subscribe if it was just ยฃ1.00 a month. We pensioners are not made of money ๐

A lot going with moving house and now the builders are in. Maybe I missed it but I don't think so. If some kind person could tell me what the question was, that would be nice..

Now that's a good question Alessandro. No one actually knows what Dark Energy is, it is all speculation. I do know it is something to do with energy contained in a vacuum. In my simple mind in order to expand, you need something to expand into. Like Dark Matter no one actually knows what it is. I have been looking into Doesn't Matter. There is a lot of it around. Most of these conjectures around the science of the cosmos can be covered by Doesn't Matter, because it Doesn't Matter.๐

This question has just reminded me of something I was going to ask the members. I was watching a BBC programme some time ago. In it there was a very modern ice breaker, which went astern into the ice. The design caused it to rise up onto the ice, thus cracking it and the propellers acted as ice crushers pushing the slush down the sides of the hull. Has anyone got any info on it or even come across it? Just add a bit more. I think it was a cargo ship and not just an ice breaker..

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.
