TP 52 Sail Configuration Guide

Overview

The TP 52, designed by Bakewell/White and built by Stevenson, is a high-performance grand prix racing yacht. This 15.84m design is engineered for elite offshore and buoy racing, prioritizing speed and technical agility.

Rig Specifications & Performance Analysis

Analysis of the Stevenson-built TP 52 dimensions reveals a powerful, modern sail plan:

• Mainsail Configuration: A P/E ratio of 2.73 indicates a high-aspect rig designed for maximum lift and windward efficiency.
• Foretriangle Design: The I/J ratio of 3.19 is exceptionally high, optimized for tall, narrow headsails and efficient airflow.
• Sail Area: 137m² total upwind area provides an aggressive power-to-weight ratio.
• Performance: Pure racing orientation requiring high-modulus materials to handle significant rig loads.

Popular Sail Configurations

• Mainsail: High-modulus square-top configurations are standard to maximize the 20.42m luff.
• Headsail: Multiple non-overlapping jibs (J1-J4) tailored for specific TWS ranges.

Key Characteristics

• High-Aspect Rig: P/E of 2.73 delivers superior pointing ability and reduced drag.
• Dynamic Foretriangle: I/J of 3.19 supports a versatile range of high-performance jibs.
• Generous Sail Plan: 137m² of upwind canvas ensures exceptional light-air acceleration.
• Technical Platform: 15.84m LOA combined with high-aspect foils for a stiff, weatherly ride.

Sailing Considerations

• Active rig management of the 20.42m P-dimension is required via backstay and runner tension.
• Full professional or experienced amateur crews are necessary to manage the 137m² upwind area.
• Performance expectations include high speeds and narrow tacking angles in all conditions.

Sailmaking Recommendations

For the TP 52, we recommend SurgeX membrane sails as the optimal choice for most owners. SurgeX uses continuous fiber construction where fibers are laid precisely along load paths and embedded in a thin membrane, providing superior shape retention compared to traditional laminates. This continuous fiber structure ensures the sail maintains its designed aerodynamic profile even under the extreme loads generated by the 2.73 P/E ratio.

For competitive racing, specify a lightweight SurgeX configuration with carbon or technora fibers and minimal film weight to reduce pitching moment. For owners utilizing the boat for fast cruising or deliveries, add a protective taffeta layer on both sides to enhance UV resistance and abrasion protection. Based on the 2.73 P/E ratio, a load-path-oriented membrane layout works best. A typical inventory includes a 76m² mainsail and a range of 61m² jibs. With 137m² of upwind sail area, plan to depower or reef around 20 knots of true wind.

Conclusion

The TP 52 is a pinnacle of high-aspect design, offering immense power and technical sophistication for the serious racer. Explore sail options for TP 52 to maximize this Bakewell/White design's potential.
