Wow. What a beauty!!!!

My guess is that the sails have been made by  the Tuchwerkstatt to a Victor Winterthun design... 
Looks efficient. I notice that one sail is on the port side and one is on the stbd. side of the mast.

Edit: Yes, that is correct.

beautiful boat, full of character!  the wood construction, and the beautiful little woodfired heater, really make it gorgeous - the pilot house is probably fantastic for enjoying northern cruising.

  if only i can reassure my wife the "klo" can be made a little less rugged!

(she asked me where the shower was.....)
