Rondo CN Biasi
Description
The Rondò CN Biasi (also known as Rondò, Rondo', or Rondo Mt 12) is a classic Italian cruising sailboat from the 1980s, built by Biasi Costruzioni Nautiche (a shipyard in Fiumicino/Rome area, Italy). It was designed by Sciomachen (a naval architect known for balanced, performance-oriented Italian yachts of that era, including other Biasi models like the Morgante 45 and Domino). This model is a solid, well-regarded sloop-rigged cruiser (around 12 meters/39–40 feet) emphasizing comfort, seaworthiness, and good sailing qualities for Mediterranean/coastal or longer passages. It's part of Biasi's lineup of semi-custom or limited-production yachts from the '80s–'90s, often with strong construction (fiberglass hulls) and practical layouts for family or couple cruising. Some examples were raced or used in events, reflecting their capable performance.
