Jacques,
Now, in the hope that the mast position can be accepted, I have drawn  a taller sail, taken from The Johanna 60 series of master sails, with AR = 1.98 (instead of the previous 1.89).This is about the tallest sail I dare to suggest. In case you will do most of your sailing, crossing oceans, I suggest you go for the lower version.

Now I had a go.
Unfortunately, to get the CE where it was in the Bermudan rig, The mast had to move a bit further forward.
The alternative would be to shorten the battens and make a taller sail, or even rake the mast forward.

If you can live with the shown mast position, then this sail will be good. A slightly bigger version (B=4.90m) (almost the same...) of this sail is already in use on two other boats, Boudicca, and Ylvi.

Arne , Sorry 

Jacques,
That looks to be a very fine boat. A sloop junkrig of about 33sqm would have the same area as the original rig with the largest Genoa.

The question is where to put the mast. Would it be acceptable to put it about 20cm forward of the hatch?

Cheers,
Arne
