Fine little boat  -  with an undersize and flat sail.

This boat will cry out to everyone that junk-rigged boats are helplessly slow...

You are definitely right Arne!

Dreaming of a new bigger boat for the future, I purchased the study plans of the “blue horizons”, a beautiful 30 footer, twin keeled, McNaugthon design. The blue horizons has a single flat junk sail.
I chatted about this and much more with Tom, the head of the company. He is an extremely kind person and experienced boat designer and for me was a pleasure and a privilege to get so much information about the boat and boat building in general. Unfortunately I was unable to convince him that a cambered sail would upgrade enormously the performance of his beautiful boats…having not much technical knowledge and experience about sail design and sail making, I suggested him to get in contact with you, Slieve or David T to have a deeper insight into this matter. Now I know that he didn’t….

Let’s imagine how better this sturdy boats could be with a big cambered sail of yours…or a SJR or a wing sail….:)

This is a very goo question Guillaume!

Also in Italy (where I was born) and in Austria (where I live), junk rigged boats are inexistent and considered in best case as exotic, wired experiments.

By the most yacht sailors I spoke with, a rig other than the bermuda one with shrouds and foresails seems almost not imaginable...even when the most diffuse sailboats in their own yacht clubs are cat boats with unstayed masts and single sprit sails (the Optimist) or Marconi sails (the Laser)!

Like Paul, I've also found most comments from Bermudan sailors about this issue simply irrational.  

Anyway, there are a lot of designers that show attraction for the JR, two examples:

MacNaughton designs, there's an article on one in Yachting Monthly.

It is a rather odd questionnaire but easy enough to do, hopefully all members will participate.

In answer to Mauro, I submitted a question on SJR to Chat GPT.  "What is split junk rig". I was not surprised that it was unable to provide any information on split junk rig but I was horrified that instead of returning no answer, it produced a lengthy spiel of complete rubbish including the confident assumption that the split is horizontal and for all kinds of spurious reasons, plus a lengthy spiel on all the cliche advantages which were of no relevance. That has diminished any credibility I would give to AI as a source of factual material (it has some other impressive uses, but not fact-seeking).

A Google search did better, and pointed directly to the JRA website and various online articles which were somewhat more relevant.

Wikipedia gave a simple definition "Split panel junk sails separate the sail plan in two sections, a main section behind the mast, and a smaller section forward the mast." and continued with some thoughtful and correct insights.
