About the Scia 50 Sailboat

Designed by renowned Italian naval architect Carlo Sciarrelli and built by Cantieri Ambrose starting in 1975, this substantial cruising sailboat represents classic European bluewater design philosophy. The generous displacement of over 28,000 pounds combined with nearly 13,000 pounds of ballast creates exceptional stability and seakeeping ability, making this vessel ideally suited for serious offshore cruising and ocean passages. The long keel configuration provides excellent directional stability and reduces leeway, though at the expense of some maneuverability in tight quarters. With a comfort ratio of 31.32, this boat prioritizes motion comfort over speed, delivering the steady, predictable handling that experienced cruisers value on extended voyages. The masthead sloop rig offers straightforward sail handling, while the moderate sail area to displacement ratio suggests reliable performance without being overpowered. Built during an era when Italian yards were establishing their reputation for quality fiberglass construction, the Scia 50 reflects traditional European cruising priorities: robust build quality, seaworthiness, and the ability to carry substantial stores for extended cruising. The capsize screening formula of 1.76 indicates good stability characteristics for offshore work, making this an appealing choice for sailors planning serious passage-making adventures.
