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

Hi RossM, when I saw these videos I thought of you.
You would be happy among these sailing geniuses, but they are too far away to reach them, too bad.
On the other hand it would be nice if some of them participated in this forum and showed us their builds in detail.
Have you seen how they maneuver the sails and how many types of sails in their channel?
The only thing I don't like so much are the weights external to the hull to ensure lateral stability, but you can't see them when sailing so it's fine.
When they are in the water while sailing, you can't even see the transparent extensions of the rudders, but without them they wouldn't be able to turn (having no propeller).

I discovered this channel today by chance.
I must say that in the last twelve years there has been a very high increase in scale RC sailing models (historical reproductions).
I noticed it because, about twelve years ago, I was frantically looking for models to copy or to inspire myself and I found very few YouTubers.
Now there are many, many historical models.
This is good for our hobby even if the average age remains very high, but this is natural.

Regarding this Youtube channel, I was very impressed because I also saw ancient models sailing with lateen sails (triangular sails typical of Mediterranean galleys).
Never seen before.
Logically they don't change sides of the flagpole either; it would be almost impossible but they tack and jibe perfectly.
The place is ideal for nautical modeling, large, beautiful and very equipped. A paradise for enthusiasts.

That was fantastic!! (Nice touch with the classic American cowboy music accompaniment!)

Wow - no wonder they don't have competitions, nobody could beat some of those models, but then they have some serious transport issues, and presumably repair issues after the collisions?

Now that is what I call modelling !
Wonderful ships beautifully modeled, and sailed in challenging conditions.😉

For lovers of sailing RC naval modeling, don't miss this recently published video.
Beautiful templates and beautiful navigations.
I think the place is closer to Wolle than Doug but still quite far away.
