FIRST 40 Sail Configuration Guide

Overview

The FIRST 40, designed by Farr Yacht Design for Beneteau, is a high-performance racer-cruiser engineered for competitive regattas and fast offshore passages. It balances a powerful, modern rig with a hull shape optimized for speed and stability, catering to serious racing teams and performance-oriented cruisers.

Rig Specifications & Performance Analysis

• Mainsail Configuration: A P/E ratio of 2.88 indicates a tall, high-aspect ratio rig designed for maximum lift and efficiency upwind.
• Foretriangle Design: The I/J ratio of 3.56 is optimized for modern non-overlapping jibs, facilitating easier tacking and precise trim control.
• Sail Area: With 82m² of total upwind sail area, the boat maintains a high power-to-weight ratio for light-air performance.
• Performance: The sail plan is distinctly racing-oriented, prioritizing close-windedness and acceleration.

Popular Sail Configurations

• Mainsail: Most owners opt for high-roach configurations to maximize the 15.93m luff length.
• Headsail: Typical setups utilize 105% to 108% jibs to maintain rating efficiency and handling ease.

Key Characteristics

• High-aspect 2.88 P/E rig provides superior aerodynamic efficiency in various sea states.
• Versatile 3.56 I/J ratio supports a range of headsails from heavy-weather jibs to light-air reachers.
• 12.24m LOA and 3.89m beam offer a stiff, weatherly platform for competitive racing.
• Farr-designed hull and rig combination ensure exceptional speed and balanced handling.

Sailing Considerations

The FIRST 40 is known for being stiff and stable, though it rewards active trimming of the high-aspect mainsail. For racing, a crew of 7-9 is optimal for weight distribution, while the boat remains manageable for shorthanded cruising in moderate conditions. Performance expectations include excellent pointing ability and responsiveness in breeze.

Sailmaking Recommendations

For the FIRST 40, 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 carbon or Technora fibers and 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 2.88 P/E ratio, a radial load-path layout works best to manage the high vertical loads of the tall mainsail. A typical inventory includes a performance mainsail, a versatile All-Purpose (AP) jib, and an asymmetric spinnaker. With 82m² of sail area, plan to reef around 18-20 knots to maintain an upright, efficient plane.

Conclusion

The FIRST 40 remains a benchmark in the racer-cruiser category, offering a sophisticated rig that rewards quality sails. Explore sail options for the FIRST 40 to maximize your yacht's potential.
