Lack of performance? Not really. And a jibe isn't a problem - in any wind strength!
Project Amazon is the first pic.
Project Amazon was an Open 60 racer, a solo boat, that even if it was theoretically interesting because of its unusual sail and mast configuration never experienced any success regarding its more "normal" competitors. the boat was considerably slower and also more expensive to built.
That was what I meant, way more expensive and less efficient
The boat was for sale for many years with a very low price without nobody touching it. I don't now if it is sold by now.
