POLO 86 Sail Configuration Guide

Overview

The POLO 86, designed by TSkjönsberg, is a performance-oriented cruiser-racer designed for balanced handling and agility. With a limited fleet of six boats, it serves a niche market of sailors who value a weatherly design for both club racing and spirited coastal cruising.

Rig Specifications & Performance Analysis

Analysis of the POLO 86 rig dimensions reveals a focus on aerodynamic efficiency:

• Mainsail Configuration: A P/E ratio of 3.68 indicates a high-aspect rig, prioritizing lift and efficiency over raw power.
• Foretriangle Design: The I/J ratio of 3.43 is well-suited for large overlapping genoas to maximize power in light air.
• Sail Area: 34m² total upwind area provides a healthy power-to-displacement ratio for an 8.58m hull.
• Performance: The combination of a tall rig and a deep 1.78m draft makes this boat a stiff, close-winded performer.

Popular Sail Configurations

Typical setups for the POLO 86 focus on versatility across various wind ranges:

• Mainsail: Full-battened configurations are common to support the tall luff and maintain leach profile.
• Headsail: Owners frequently utilize a 130-140% genoa for light air, transitioning to a non-overlapping blade jib as the breeze builds.

Key Characteristics

• High-aspect P/E ratio ensures superior upwind lift and efficiency.
• Versatile I/J ratio allows for a wide range of headsail sizes.
• Deep 1.78m draft provides excellent tracking and resistance to leeway.
• 2.82m beam offers a stable platform for the 34m² sail plan.

Sailing Considerations

The POLO 86 is highly responsive to trim, performing exceptionally well in light-to-moderate conditions. Due to the high-aspect rig, the boat requires proactive reefing and backstay tensioning to manage the heeling moment as the wind exceeds 15 knots. A crew of three is typically sufficient for competitive racing, while the boat remains manageable for shorthanded cruising.

Sailmaking Recommendations

For the POLO 86, 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 in light air and minimize pitching moment. For cruising or coastal sailing, add a taffeta protective layer on both sides to enhance UV resistance and abrasion protection. Based on the 3.68 P/E ratio, a tri-radial fiber layout within the membrane works best to handle the high vertical loads of the tall mainsail. A typical inventory includes a 14m² mainsail and a 19m² 135% genoa. With 34m² of sail area, plan to reef around 14 knots to maintain optimal hull speed without excessive heel.

Conclusion

The POLO 86 is a refined sailing platform that rewards high-quality sail shapes and precise rig tuning. Explore sail options for POLO 86 to maximize your boat's performance and longevity.
