Not too many on the market.
The Ovni 435 is the perfect choice for long distance cruising. 100% Aluminium hull and deck gives this boat a exceptionaly strenght. The centerboard system reduce the draft from 2,54m to 0,74cm and allowes to enter small bays or beaching.
This Ovni 435, "Balanec" is in perfect conditions and is very well equiped and ready to go for round the world tour.
If you don't know that kind of boat, experienced sailors choose Ovni, as a reference, Jimmy Cornell completed a five-year circumnavigation on Aventura III, an Ovni 43 built by Alubat, in 2006. Since her launch in early 1998, Aventura III has covered over 70,000 miles. On his website Jimmy answer many questions about Ovni boats.
There is an owner website for more info.
