Good, Eero.
Then I guess I would suggest one of the two last rigs I have presented.
The light winds in the Bay of Finland during summer, speaks for the last one; the one with AR= 2.40 and SA= 65.6sqm.
However, we don’t get younger as the years go by, and the shorter 13.4m mast is cheaper and easier to deal with than the one at 14.9m...
As for performance; even the smallest JR will outperform the masthead Bermuda rig on the downwind leg. Close-hauled, I guess I would put my money on the BR, in light winds.
The only ‘hard’ job when sailing with a JR, is hoisting the sail. On your boat, that can easily be overcome with an electric capstan. Some of these are meant for hauling up the anchor, and are not terribly expensive. Hoisting the sail from bottom to top will drain a 12V battery with less than an Ampère-hour.
Anyway, rigging the boat with two sticks will cost a lot more - I would say, forget that.
When organising the sheet, it is important to give them a good layout to make them easy to haul at by hand and via manual winches.

PS: I have sent the drawing in QCAD (.DXF format) to David, to let him suggest a rig. If others will have a go, and can handle that format, just let me know.
PPS: In case the mast position I have suggested results in awkward access to the fore-peak, the mast may well be moved 10-15cm forward, and it can even be offset 10-15cm to one side, without suffering any handling problems.
