Performance Predictions based on the Design Ratios

The Jeanneau International 50 sailboat, owing to its design ratios, is expected to have a solid performance.

• With a Sail Area/Displacement Ratio of 18.8, the vessel is likely to deliver an excellent speed performance, especially in light and moderate wind conditions.

• Its Displacement/Length Ratio of 194 indicates that it is a light displacement sailboat. If she's equipped with a full crew and loaded with too much heavy cruising gear her performance will suffer to a degree.

• The Ballast/Displacement ratio is not specified, preventing a thorough interpretation of the boat's stability and ability to manage wind gusts. However, as she has much of her ballast concentrated in a bulb at the foot of her keel, she's likely to be a stiff boat.

• The Comfort Ratio of 28.7 suggests the sailboat offers a reasonable level of comfort, suggesting that it won't provide a lively sailing experience in boisterous conditions.

• Lastly, the Capsize Screening Formula of 1.99 is below the safety threshold of 2.0, which suggests the boat has a lower risk of capsize and is generally considered safe for offshore cruising.

Please keep in mind that these are predictions based on the design ratios provided, and actual performance can depend on several other factors.
