Hi Row,
if was possible I would had used ! There some places closer but are at open sea with usual disturbing waves. Good for fleet races but certainly not for launch testing. The trip is about 36 miles (45 minutes drive).
At the time I left Toulouse in 1998, when I stopped my professional work, the driving idea was to get closer to a nice sea side place where to put my full mahogany Dragon Styx-II, that I restored my self with some 1700 hours of work in 2-1/2 years time.
Finally the choice was Cannes where the French Mediterranean Dragon fleet is sitting while for the living home we choose Nice being a very nice city with all excellent facilities that an old couple may need!!
At that time I didn’t told about RC models places !
Now the Dragon is gone after 5 years of fantastic sailing around Cannes and the best pond for the RC sailing is in Villepey, hoping that it will last for some time …
Thanks John,
Was one of the unique places we where looking for since years, but forbidden until 6 months ago being considered a private resort !
I will ask around if they have changed their mind !
Cheers

Testing went very well with 123 yesterday amongst crazy weather pattens in the area, the boat has perfect helm balance the moment it hit the water and goes like a rocket, had to spend last hours in the day calming down Claudio excitement; thought I was bad enough with a new boat but he is over the moon :spin:
Vid is currently being processed and should be up later today.
Jaguar had trouble keeping abreast of her AND sails settings of 123 were far from perfect …so 123 looks much faster before I hit an electrical problem and had to stop sailing Jaguar.
just saw the video - congratulations on a fantastic boat. she seems to float right on her waterline, great acceleration, not suffering of bow digging in the run and good heeling angle. the sails trim look with a bit too much twist but difficult to check from a video. any water inside ?
Thanks for sharing - well done… nice video showing how she sails.
Noted in the audio comments that you are using independent sail winches? OR is it one winch and a trim servo?
I have a small boat (with 150% genoa) that I am running two winches on - it took me quite a while to get used to controlling two sails on the one stick but is getting easier with some practice. Using a genoa, of course you have to haul the genoa across the boat each time you tack… but the performance is much better than with the original jib…
My controls:
Left stick down = mainsail hauled in
Left stick up = mainsail sheeted out
Left stick left = genoa hauled to port side
Left stick right = genoa hauled to starboard side
Left stick has all centering removed so it stays where you leave it
Hi Gilbert,
The Wang was not going any further to pull down the Main leech; I shall modify it !
No real leakage. Except a couple of drops probably collected during a raining period that fortunately did not lasted very long compared to the big storm we got on the motorway just half hour before.
Wind speed from the initial 6 kn went up to 13-15 kn with gusts up to 17-18 kn and may be more !
At the end of the film, the boat was sailing so fast that I couldn’t stop it at the arrival ! No damages.
For my first experience, time to time, I was missing the Jib and Main joystick adjustments. Two separated winches !
It may be probably necessary to increase a little the rudder surface, but the rudder was operating on the same joystick of the Jib and some time I miss to complete the 180° turn.
Some time the main was closed when the Jib was open during running, again for the same reasons about two independent servos.
All in all , the boat is very fast with brutal accelerations and no “nose down” at all, at the contrary the bow was lifting, time to time, like it was trying to start surfing ! It can be observed the wave splitting at the bow .
As Alan says, this model may not need to add a flared bow !
The next model drawing updating will insert a single servo winch for Main and Jib with a independent trimmer on the jib

I’m thinking about this solution in order to cope with the wind force on the sails : The torque value available will be as function of the drum radius. In this case 4,6cm. Savox 1268 is given for 15kg.cm = 3.26 kg.cm with the 90mm drum HS-7950 is given for 29kg.cm = 6.3kg.cm with 90mm drum This graphic define the wind Force in Kg as function of sail area and wind speed. The 1.2.3. may requires for 77/78dm², 6kg force at 20kn., it is also assumed that the HS-7950TH could be sufficient unless I made mistakes. Any suggestions or comments ? ClaudioD
Hi Claudio - Very nice job and looks good on the water. Do you have any plans to sail it against the AZUR “M” class boat? It would be interesting to see a comparison of this against the Marblehead size - and if close in performance, think about increasing size to match the “M”. I say that only because the “M” Class would provide a direct comparison of performance, but there is no class to compare against at this size - so it would seem, that one would want to compare on a given “yardstick” - either at 1 Meter size or at the “M” class size?
I have a similar problem in comparing my 1 Meter and my Formula 48 multihulls with others, as no one lives close enough to test. By themselves on the water, a single boat always looks fast - until a second boat of same size appears. Then the truth is seen. :rolleyes:
My concern would be the possibility to drop a turn off the drum. Many IOMs use a drum with either a tension elastic or a full loop/return system to keep tension on the drum and prevent dropping a turn.
Hi Dick,
On paper, as said already in this discussion, the 123 is similar in weight and probably 200g lighter then the Class M characteristics , but the most difference is the sail surface, 7200cm² against 7800cm².
For sure, after new model construction including all modifications registered (construction only) there will be opportunity to test it against class M in the water.

Hi John,
Your contribution is very welcome ! Thank you.
First will be a deep throat pulley self made with entrance ring guides.
Second there will be small pulleys and pulling elastics acting as tensioner.
The most critical is the servo for 360° only and additional end stops if necessary.
All inside reasonable weight !
The matter is still fresh in my mind and I need to digest it.
Cheers
Claudio
PS: Alan left Nice this morning at 9am and is just arrived in Heidelberg (Germany) almost after 10 hours driving at about 7.30pm - CE time
