I didn't say, that Viko doesn't sail well. I just said, that it didn't impress me, especially the interior quality was poor. Visit the boat on a show, and you'll know wiat I'm talking about.
I like to sail fast, I'm not a lazy cruiser, and feel really happy with Sedna... 8.3kn isn't bad for a 9m centerboard cruiser
My point wasn't to criticize or promote any boat. I just wanted to share my impressions about this interesting sailboats, whic were posted here(i consider myself to be the only one here who has seen them and sailed two of them(sedna 26 and 30)).
Btw, I would say, that you can make any boat, a really fast one. Excluding Delphia, most of the polish boatyards are open to your demands, so, as long as it doesn't mąkę the boat any dangerous, you can have anything you want-interior layout, rigging, keel, lifting keel, centerboard, extra ballast, bigger sails etc...
