TEN PF Sail Configuration Guide

Overview

The TEN PF, built by Maxi Dolphin and designed by the Frers/Pelaschier team, is a high-performance daysailer and cruiser-racer. It is engineered for sailors who demand elegant aesthetics combined with competitive speed and responsive handling.

Rig Specifications & Performance Analysis

Analysis of the P/E and I/J dimensions reveals a sophisticated rig optimized for efficiency:

• Mainsail Configuration: A P/E ratio of 2.65 indicates a balanced, moderate-aspect rig that provides a versatile power profile across various wind ranges.
• Foretriangle Design: The I/J ratio of 3.35 is tailored for high-aspect headsails, facilitating superior upwind pointing and ease of tacking.
• Sail Area: With 48m² of total upwind area, the boat maintains a favorable power-to-displacement ratio.
• Performance: The design is distinctly weatherly, excelling in close-hauled performance thanks to its Frers-designed underwater profile and high-aspect rig.

Popular Sail Configurations

Configurations vary based on the specific fleet requirements of the two existing hulls:

• Mainsail: Usually high-modulus constructions with full battens to support the 2.65 aspect ratio.
• Headsail: Optimized as non-overlapping or slightly overlapping jibs to leverage the 3.35 I/J ratio for maximum aerodynamic efficiency.

Key Characteristics

• Moderate P/E ratio (2.65) ensures manageable sail loads and effective reefing geometry.
• High-aspect I/J ratio (3.35) promotes efficient lift and narrow tacking angles.
• Deep 2.12m draft on a 9.99m LOA provides the stiffness required to carry 48m² of sail.
• The Frers-designed hull remains balanced and responsive even when pressed.

Sailing Considerations

• The boat is optimized for a small crew, requiring sails that maintain shape without constant trimming.
• High performance is expected in light to moderate air, where the 48m² sail area can be fully utilized.
• Its stiff nature allows for maintaining a full plane in higher wind speeds than typical 32-footers.

Sailmaking Recommendations

For the TEN PF, we recommend SurgeX membrane sails as the optimal choice for most owners. SurgeX utilizes continuous fiber construction where technical fibers are laid precisely along load paths and embedded in a thin membrane. This provides superior shape retention compared to traditional Dacron while remaining more cost-effective than premium carbon laminates. The continuous fiber structure ensures minimal stretch, preserving the designed foil shape for years of active use.

For racing-focused TEN PF owners, specify a lightweight SurgeX configuration with a minimal base weight to maximize light-air responsiveness. For those prioritizing coastal cruising, we recommend adding a taffeta protective layer on both sides to significantly enhance UV resistance and abrasion protection. Based on the 2.65 P/E ratio, a tri-radial fiber layout works best to handle the diagonal loads in the mainsail. A typical high-performance inventory includes a square-top or high-roach main and a suite of high-aspect jibs. With 48m² of sail area, plan to take the first reef around 16–18 knots to maintain a flat, fast profile.

Conclusion

The TEN PF is a refined sailing machine that performs best with high-modulus, shape-stable sails. Explore SurgeX membrane options to enhance the performance and longevity of your TEN PF sail inventory.
