FIRST 32 S5 Sail Configuration Guide

Overview

The FIRST 32 S5, designed by Jean Berret for Beneteau, is a performance-oriented cruiser-racer that balances modern design with a nimble, capable hull. It is specifically targeted at club racers and coastal cruisers who demand a responsive boat with sophisticated interior styling.

Rig Specifications & Performance Analysis

• Mainsail Configuration: A P/E ratio of 2.82 indicates a tall, high-aspect rig that prioritizes aerodynamic efficiency and upwind lift.
• Foretriangle Design: The high I/J ratio of 3.97 is optimized for large, high-aspect genoas, providing significant drive in light-to-moderate conditions.
• Sail Area: 42m² total upwind area delivers a competitive power-to-weight ratio for a 9.44m hull.
• Performance: The sail plan is engineered for speed and agility, favoring technical sailors who appreciate a weatherly and close-winded design.

Popular Sail Configurations

• Mainsail: Owners typically choose between full-batten configurations for cruising stability or partial-batten setups for refined racing trim.
• Headsail: Configurations vary from 140% overlapping genoas for light-air performance to high-aspect blade jibs for heavy-weather control.

Key Characteristics

• High-aspect mainsail design ensures superior pointing ability and lift-to-drag efficiency.
• Aggressive I/J ratio allows for powerful overlapping headsails to maximize light-air drive.
• 3.26m beam provides the necessary form stability to carry its 42m² sail plan effectively.
• Berret-designed hull remains balanced and responsive, offering a stiff feel in a breeze.

Sailing Considerations

• The tall rig configuration suggests proactive depowering; reefing is generally recommended when apparent wind exceeds 17 knots.
• Highly manageable by a crew of two for cruising, while a racing crew of 4-5 allows for optimal weight distribution.
• Performance is characterized by quick acceleration and a high degree of responsiveness to backstay and car adjustments.

Sailmaking Recommendations

For the FIRST 32 S5, 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 light-air performance and acceleration. For cruising or bluewater sailing, add a taffeta protective layer on both sides to enhance UV resistance and abrasion protection. Based on the 2.82 P/E ratio, a tri-radial layout works best to handle the vertical loads of this high-aspect rig. A typical inventory includes a full-batten mainsail and a 135% furling genoa. With 42m² of sail area, plan to reef the mainsail around 16 knots to keep the boat on its feet and maintain speed.

Conclusion

The FIRST 32 S5 is a sophisticated cruiser-racer that rewards high-quality sail inventory and precise trim. Explore SurgeX membrane sail options for your FIRST 32 S5 to maximize both durability and racing performance.
