The Varianta 44 is indeed quite a stunt. All tests I have read agree that the boat not only sails very well, but that the concept as a whole also seems to work.
Of course everything is very basic, the edges are sharp and also the canvas stowage will not last long.
But let's be fair, the difference between 100.000€ and the standard price for any other yacht this size will give you quite a margin for improving comfort and equipment. Even if it does not seem to make sense to upgrade this boat to a fully equiped luxury yacht.
I think it will certainly appeal to families with children and charter crews who just want to enjoy sailing for short periods of time. And I also agree with Paulo that the faces on some fancy racers might turn green...
