Hello Rogal
Your build would seem to be going extremely well and I might add quickly, "writes the tortoise".
The plan and my donor Inga would suggest your positioning of the three sail sheet holes are spot on.
As for the winch or arm method of sail control I agree with Roy that the arm method rather than the winch is efficient, easier to set up and works well, probably less expensive as well but I must admit the system on Michael Turpin model is beautiful to see and if I were capable of a system that good I would go for it.
I am going for an arm as I have one ready to go. I have fitted a 600 motor nothing special as a sailing model is what I am looking forward to not a power boat.
For a new boy to sailing you are doing brilliantly and I am looking forward to seeing the boat on the water and would like an invitation to the ceremonial launch.
Keep up the excellent work in 2024.
All the very best ChrisG

Hi Roycv. Thanks for that info. I've not decided yet whether to go down the drum route or the arm type, the 1 and 2 drum systems seem very complex with its pulleys and springs etc. whereas the arm, from what I gather does the job as well. now this maybe my novice naivety that hasn’t grasped the working mechanics sufficiently but I feel to get me going the arm system is a good place to start and learn. Then once on the water I will see hopefully the pros and cons of the best way to go. Your other question, yes the motor is fitted a brushed 540 with 50mm 4 bladed prop, 6v with a quicrun 1060esp and 8 ch futaba radio 2.4ghz. Also as you have probably seen from the previous photos the masts came out spot on, and gave me an insight into how to make the booms. Which I am very satisfied with.

Hi Roger, If you are using an arm winch perhaps try a metal gear 17Kgrm standard servo.
That is powerful enough to work all 3 sails, you would need to make an arm that screwed down onto a servo top. Howes have them at about £10.

They are a lot simpler to set up as well.

If you go for a larger winch there is more than one way to set them up.
I use the simple system of a cord out to a pulley and the cord has an elastic return attached and winds back on the TOP of the 2 winch drums.
You can get a 1mm plastic cord that stretches enough for the job. Do not use Shirring elastic as it degrades after a while.

Which ever way you use a pulley system you will need to be able to tension it otherwise it goes wrong.

The servo is rated at 17Kgrms at 1 cm. So effort reduces at the end of the arm. A winch has a constant pull as it is a rotation.

Have you fitted a drive motor yet?

regards

Roy

Hi there DuncanP
Thanks for your interest the foresail and mizzen sails have the brass tubes already fitted by the original builder, the first is forward of the main mast and the mizzen is right on the stern aft of the railings. the main mast control line exits on the raised hump centrally just behind the wheelhouse seating. But as I’ve just built the rear cabin this has not been drilled out yet.The rear cabin was missing when I purchased the barn find hull. as for your question regarding the winch set up this is my next project. I have not owned a sail yacht before and it is taking a lot of research to fill the old grey cells with the correct information, to proceed, I’ve a basic idea what is wanted and the mechanics are understood. I think the best way is to dive in and learn by trial and error, or I could wait for you to post and follow you!. So if any fellow modellers are reading, can you point us in the right direction???. The photo shows where I intend to position the hole for the main mast control line, it also shows more clearly the wheelhouse seating.

Beautiful model with excellent detail - well done! I'll be very interested to see where you put the holes in the deck for the sail control lines. Also a diagram/photos of how you have arranged the winch/winches mechanism. I've got to plan how to do this on a similar type of yacht. 😊

Hi I was driving a dinghy with an electric outboard in the Spring this year. A small 1KW easily takes the place of a 3 HP i/c outboard. Almost silent.
The battery unclips and you can easily carry it into the restaurant, if arriving that way.

While having lunch by the water we watched a small seaplane land from Sydney arriving at Cottage Point (Hawksbury River). Part of an all in afternoon!

Hi Roger that is a very nice looking yacht!

Nice touches with the dinghy (they have electric outboards these days).
Possibly the iPad for navigation?
Love it.

Good morning all a productive day today in the hideaway. Put finishing touches to the rear cabin still some parts to add though.the centre wheelhouse has had the wheel and instruments added, along with the colour matched seating. Also added parts to the tender dinghy so as to take the blandness off the foredeck. Still waiting for the screw jacks, it’s been 2 weeks now. I’ve ordered the cambric cotton material for the sails. I feel confident I can make them up, I’ll have a go anyway. If not I will have to buy them in. All the best Roger.
