Andrew,

here is how I presented four versions of the Johanna-style sails:

Arne, thank you. Sorry its taken a while for me to respond, I've got too much going on at the moment! I had a good poke around in the cabin the other day and on deck and the best possible position for the mast would be just in front of the deck slope. It's clear, top and bottom, retains the forward hatch, doesn't obstruct the door to the heads and even allows for some shenanigans in the forward berth!
Do you think I can assume that as a mast position and adjust the balance accordingly?

Andrew, I found a position just ahead of Kingfisher 26 Antares's coachroof worked well. That's where I'd put your mast. Junk rigged Kingfishers were sold with the mast stepped through the forward slope, with cast aluminium partners shaped to conform. Beken's photo shows the sail hauled forward to ease the helm on a broad reach. The broker's photo was taken while she was sold most recently.

Andrew,

here is how I presented four versions of the Johanna-style sails:

• The lower the yard angle, the bigger the mast balance you get for the same halyard angles...

..and...

• the lower the yard angle, the taller mast will be needed to get the same sail area.

(full size diagrams at Arne's sketches, section 6-46)

Still, now I have tested a yawl alternative on that Sabre. As you can see, that little 3.5sqm jigger will move the CE over two feet aft of the CE of the junk sail alone.
Lots of work with that extra mizzen, but at least, installing the main mast will now be easy.

Arne, that is a very interesting concept but I'm afraid it's not for me. I'm sure there must be a better way? Doesn't the original Johanna sketch work on its own?

Hi everybody !

I follow the posts debating the merits of different junk rig configurations with great interest and would gladly weigh in, but I would like to draw attention to another matter: my forays into the forum archives last winter revealed that many posts become completely useless when they contain images inserted via "Ctrl-C, Ctrl-V." 

Such images vanish forever into the forum's depths, leaving behind empty frames; even if the author remains a JRA member, they likely won't remember what the images depicted after a while. 

Therefore, until the bug  (feature ?)  causing "copy-paste" images to disappear is fixed, I would still recommend using the "attach file" method for posting images on the forum. 

Of course, this is just my personal opinion.

Regards- Jan
