SOLARIS 50 Sail Configuration Guide

Overview

The Solaris 50, designed by Acebal, is a high-performance cruiser-racer that balances elegant Italian aesthetics with functional offshore capability. It is engineered for sailors who demand a stiff, fast platform for both competitive club racing and sophisticated coastal cruising.

Rig Specifications & Performance Analysis

• Mainsail Configuration: A P/E ratio of 2.91 indicates a high-aspect-ratio rig designed for vertical lift and upwind efficiency.
• Foretriangle Design: The I/J ratio of 3.57 is optimized for modern high-aspect headsails, favoring ease of handling and tacking speed.
• Sail Area: 136m² total upwind area provides a powerful displacement-to-sail area ratio.
• Performance: The sail plan is heavily oriented toward weatherly performance and close-hauled efficiency.

Popular Sail Configurations

• Mainsail: Most configurations utilize a full-battened mainsail to stabilize the large 71m² area and maintain the 2.91 P/E aspect ratio.
• Headsail: Common setups feature a 105-108% non-overlapping jib to maximize the efficiency of the 21.45m I-dimension.

Key Characteristics

• High-aspect 2.91 P/E ratio provides exceptional lift-to-drag efficiency upwind.
• Large 3.57 I/J foretriangle supports powerful, easily handled headsail options.
• 15.38m LOA and 4.53m beam provide a stable, weatherly platform for offshore work.
• 136m² sail area ensures competitive performance across a wide range of TWS.

Sailing Considerations

• The boat is notably close-winded, rewarding precise trim of the high-aspect rig.
• While manageable for short-handed cruising, the 136m² sail plan benefits from a crew of 2-4 during maneuvers.
• Expect the yacht to remain stiff, though the 71m² mainsail requires reefing at approximately 18-20 knots to maintain helm balance.

Sailmaking Recommendations

For the SOLARIS 50, we recommend SurgeX membrane sails as the optimal choice for most sailors. SurgeX uses continuous fiber construction where fibers are laid along load paths and embedded in a thin membrane, providing superior shape retention compared to traditional Dacron while being more affordable than premium laminates. The continuous fiber structure means less stretch over time, maintaining the designed sail shape for years.

For racing applications, specify a lightweight SurgeX configuration with minimal base weight to maximize performance. For cruising or bluewater sailing, add a taffeta protective layer on both sides to enhance UV resistance and abrasion protection. Based on the 2.91 P/E ratio, a radial fiber layout within the membrane works best to handle the high vertical loads. A typical inventory includes a 71m² mainsail and a 64m² furling jib. With 136m² of sail area, plan to reef around 18 knots.

Conclusion

The Solaris 50 rig is a masterclass in high-aspect design, offering a versatile foundation for both racing and performance cruising. Explore sail options for SOLARIS 50 to optimize your yacht's speed and handling.
