Hi Georg, the short answer is yes. Every rig, boat, car, house and I dare say, woman is a compromise between what you would like and what you can actually afford, manage or put up with. I should say at this point that these are my own opinions. There will be plenty of others.
The flat, original rig is good offshore and for long voyages but could be frustrating for weekend use.
Hinged battens. Better performance but seem to have gone out of favour. Perhaps too difficult to make or unreliable for the long term.
The pillowed rig (Arne Kvernland) seems to work very well but is complex to make at home.
The split-rig (Slieve McGalliard) also seems to work well but is just as complex to make and slightly more complex to design.
The above rigs all have straight simple battens, most with complex sails. The following have wishbone battens with simple flat sails.
The wishbone rig. This time you have the original flat sail but the wishbone battens give the camber. Faster than the original but the batten width could make one side of the boat impossible to walk along.
The AeroJunk Rig. This is my latest design that I got working successfully last year. It is fast, efficient, easy to use and reliable as it survived a gust that laid the boat flat. With this rig it is possible to have the mast further astern than most junks. (With a fractional-rig donor boat it can go in the same place as the original.) I am testing a generic design of this rig for 2014 that will eventually have full dimensional ratios that can be applied for most sizes of rigs.
Wing sails. Again use wishbone battens and there are claims for its efficiency but I am not convinced yet that it is any better than my AeroJunk.
So, as you can see, lots of choice. Better you decide first which compromise you can put up with! Paul McKay
