The Ovni 445 is a 45-foot aluminum-hulled lifting-centerboard bluewater cruiser designed by Mortain/Mavrikios and built by Alubat in Les Sables-d'Olonne, France from 2013 through 2023. Her multi-chine aluminum hull and hydraulically-operated steel centerboard give her an extraordinary draft range — 3'5" with the board fully raised for exploring shoal anchorages and drying out on the beach, extending to 9'10" when deployed for upwind passage-making. A fractional sloop rig, protected hard dodger, and well-engineered interior have made the Ovni line a favorite among high-latitude sailors, Northwest Passage cruisers, and anyone prioritizing the toughness and beachability of an aluminum centerboarder. The 445 was replaced in the range by the Marc Lombard-designed Ovni 450 in 2019 but remained in production alongside it for several years.
