Alessandro,
There is VINTAGE MODEL YACHT GROUP which operates in both Europe and North America. They operate restored or reproduction vintage yachts. I am a member. (they have plans!!)
I would not have thought lateens could work with RC control
I counted at least 3 schooners

That's not punched, its burned. The first two (on the left) were too big. The third (far right) is about right. Currently in testing on the RG65. That's Ripstop Nylon, takes the heat well.

Yes, that would be the issue. You would have to move the sheet exit point from the deck, back further. This gets complicated quickly.

Glad I could be of assistance.
Would moving the mainsheet attachment point on the boom closer to the mast give you more range of movement of the boom to full out?
I do this alot with the DF65 to adjust the boom because it is so simple to adjust the attachment on a DF65

can your pulley handle the LOOP LINE, MAINSHEET, and ELASTIC LINE volume?
This is going to be a BUSY pulley. can you put the tensioner on the back side of the loop? 2 idler pulleys side-by-side with the tensioner pulley between them, pulling away. the usual method. see also my KUBOTA picture. I think some elastic line might suit you for the tensioner spring

A simple LOOP KNOT in the LOOP LINE
expanded size for display. Tightened and half tightened
Then tie the mainsheet to that loop
repeat to tie the elastic to the mainsheet 4 inches or so down the line
anchor elastic other end to the SHEET SIDE of the loop

Main sheet is tied to the loop line
Elastic is tied to the mainsheet, about 4 inches down
Elastic begins to stretch as the mainsheet rounds the pulley
This keeps the tension on the mainsheet as it rounds the pulley
Travel is about 4 inches more as the mainsheet rounds the pulley
I think all you need is an 8 inch elastic in the right place

ELASTIC
I am thinking that the elastic will be too tight at full extension and too slack at retraction. SET THE ELASTIC ON THE OTHER SIDE OF THE LOOP
Can you bring the mainsheet AROUND the upper PULLEY to gain the extra length? That would mean that you would have to rout the MAINSHEET right along side the PULLEY LOOP line and attached to the elastic that tensions as it rounds the pulley.
Have the ELASTIC line tug on the MAINSHEET, JUST AS IT STARTS AROUND THE PULLEY, to keep it seated in the pulley. Is that what you were thinking in your diagram? So the elastic would only have to stretch the distance between LENGTH BETWEEN THE PULLEYS and LENGTH OF MAINSHEET. Approximately 5 inches. Shows ELASTIC at FINISH POINT

Just an idea . . .
Instead of running the sheet from the 'too short' MAIN SHEET LOOP, (because the loop is too short), run the required LEVER from the MAIN SHEET LOOP.
How much lever length-arc do you need to run the MAIN SHEET?
How much run do you have on the MAIN SHEET LOOP?

Is this the Bristol Pilot Cutter- THREE DAUGHTERS?
Is there a tensioner pulley? I have spent many years with continuous loops and tensioner pulleys. The tensioner pulley is in the centre, the spring is along side it (a Kubota). It doesn't slack or tangle
BillH2 is correct

Yes Alessandro, you are correct
The JIBS WINCH is doing a similar job to the STAYSAIL WINCH. PORT & STARBOARD lines up and over the JIB TOPSAIL STAY & the JIB STAY, 4 lines
PORT JIB TOPSAIL
STARBOARD JIB TOPSAIL
PORT JIB
STARBOARD JIB
So the STAYSAIL WINCH can be a copy of the JIBS WINCH

๐ STAYSAIL CONTROLS

๐จ๐ฆ RossM (
![](https://model-boats.com/media/site/ranks/12.png)

Alessandro
There are actually 4 lines 2 starboard 2 port (at top and bottom)
One pair pull around foresail to port side, the opposite pulls around foresail to starboard side
The line to left and the lower line are the slack line that travel around the foresail. The line to right pulls to foremast
Using your diagram, the slack, dotted line doesn't go from behind the foresail to the mainsail, the slack, dotted line goes from behind the foresail to the luff of the staysail. Pulling on that dotted line will (hopefully) pull the staysail to the rear of the foresail and then back up the the front of the foresail, on the other side.
The staysail remains attached to the mainmast at all times

Alessandro,
Thank you for your support! By LEACH of the foresail, I was referring to the rear edge of the foresail. The leach of a schooner foresail is almost vertical. It may not be clear from the video, but the line that travels around the rear of the FORESAIL will always be slack, the second line will take the tension. It will then be reversed as the STAYSAIL moves aft of the FORESAIL, to the other side. If I am not explaining properly ask again, I need your challenges.๐

๐ sailing 6 channel
1 month ago by
๐จ๐ฆ RossM (
![](https://model-boats.com/media/site/ranks/12.png)
Lieutenant)
Flag
Ah, Mr Holmes, you saw through my attempt to misled you with a very thorough answer to only half the question!
The second half
Why?
Firstly, to see if it could be done. Could a 6 channel vessel be put together and operate as hoped? The evidence for and against is still being gathered. More later.
Secondly, 52 years ago I created my own design of schooner, much smaller and simpler. It sailed in breezes I couldn't even feel, a good light wind boat. Total sailing time on that hull might have been 2 hours before life got in the way and it was left behind (ROSEBUD).
Now I have all the time in the world
Thirdly. my design time greatly exceeds my sailing time. So I need lessons and practise. The local model sailing club has been very generous with their time, knowledge, and experience. They have shown me that even the simple 2 channel class racing boats are tuned to performance. Millimeters and grams count in winning races. So, minute changes in configuration, greatly change performance. I have spent most of my career working with and against wind and water, constantly readjusting to adapt. I can now do it as a hobby.
I carry the adjust-adapt philosophy with me to the boat.
The more adjustments that you can control, the better the adaption to the conditions, and the better the performance. I have seen your work displayed here, you do strive for better performance. Your construction performance is art. With more sail controls you can improve your sailing performance. Be it better sailing in light winds (my staysail), faster speed (adjusting the slots between the sails for optimal flow), faster tacking (controlling the jibs), sailing closer to the wind (each sail will have its own optimal setting for maximum force). In the end, it will be how pleased you are with your better performance. You have achieved that with your construction performance. Are you ready to take it to your sailing performance?

Alessandro,
In my 'previous' life (sounds a little Buddhist, doesn't it) operating a skid steer loader (BOBCAT S70 LOADER, if you want to Google it) required left heel control, left toe control, right heel control, right toe control, left arm control, right arm control, strapped into the bouncing machine in a roll cage. ( one of my operator flipped one on its side, they got it back upright on their own and didn't tell me for 2 weeks). To transport this equipment on a truck in a snowstorm, was up 2 ramps 45cm wide, backwards, in the dark about two thirds of the time. I had about 2000 hours on skid steers. I could go on further about 14 hours days in a plow truck, it's boring. Sailing 6 channels is a retirement holiday requiring 2 thumb control and 2 fore finger control. enough of my rant

The transmitter is a FLYSKY FS-i6 6 channel, connected to FS-iA6B 6 channel receiver, running 6 servos, (one rudder and 5 winches). 1 servo for each channel.
3 channels are running 2 sails each
1 JIB & JIB TOPSAIL
2 FORESAIL & FORE TOPSAIL
3 MAINSAIL & MAIN TOPSAIL 6 sails
2 channels are running 1 sail each
1 JUMBO JIB
2 STAYSAIL 2 sails
8 sails when the STAYSAIL control is complete
5 WINCHES
