SEAWIND 32 Sail Configuration Guide

Overview

The SEAWIND 32, designed by Eivind Still and built by Muovi-Simola, is a performance-oriented cruiser-racer. This 9.75m yacht balances a high-aspect rig with a capable hull, making it suitable for both competitive club racing and fast coastal cruising.

Rig Specifications & Performance Analysis

• Mainsail Configuration: A P/E ratio of 2.71 indicates a high-aspect rig, optimized for efficient lift and superior upwind pointing angles.
• Foretriangle Design: The I/J ratio of 3.21 suggests a versatile foretriangle that suits large overlapping genoas for light air performance.
• Sail Area: 41m² of total upwind area provides a strong power-to-displacement ratio for a yacht of this size.
• Performance: The combination of a 1.80m draft and high-aspect sail plan results in a weatherly vessel that excels in light-to-moderate conditions.

Popular Sail Configurations

• Mainsail: Owners typically utilize full-battened configurations to maintain the 11.40m luff profile and improve durability.
• Headsail: Common setups include a 135-140% genoa for light air regions or a 100% working jib for heavy-weather stability.

Key Characteristics

• High-aspect mainsail (P/E 2.71) for maximum aerodynamic efficiency.
• Generous foretriangle (I/J 3.21) allowing for powerful reaching sails.
• Deep 1.80m draft provides excellent stiffness and tracking.
• Balanced 3.12m beam supports the 41m² sail plan without excessive heel.

Sailing Considerations

• Proactive reefing is recommended as true wind speeds approach 18 knots to maintain helm balance.
• The boat requires precise sheet tensioning to capitalize on its high-aspect design.
• Crew requirements are modest, with 3-4 people ideal for competitive racing.

Sailmaking Recommendations

For the SEAWIND 32, 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 2.71 P/E ratio, a tri-radial fiber layout works best to handle the high vertical loads. A typical inventory includes a 24m² mainsail and a 17m² furling jib. With 41m² of sail area, plan to reef around 16 knots to keep the boat flat and fast.

Conclusion

The SEAWIND 32 is a sophisticated Eivind Still design that excels when paired with modern, low-stretch materials. Explore sail options for SEAWIND 32 to unlock its full racing and cruising potential.
