OLSON 29 Sail Configuration Guide

Overview

The OLSON 29, designed by George Olson and built by Pacific Boats, is a high-performance racer-cruiser optimized for agility and speed. It targets competitive club racers and coastal sailors who prioritize responsive handling and a weatherly profile in a light-displacement platform.

Rig Specifications & Performance Analysis

Analysis of the OLSON 29's dimensions reveals a rig designed for efficiency and versatility across various wind ranges:

• Mainsail Configuration: A P/E ratio of 2.82 indicates a high-aspect rig, offering excellent lift-to-drag ratios and superior pointing ability.
• Foretriangle Design: The I/J ratio of 3.09 provides a generous foretriangle, supporting powerful genoas for light-air performance while remaining efficient with working jibs.
• Sail Area: 35m² total upwind area on a 9.05m hull suggests a high sail-area-to-displacement ratio.
• Performance: The design is heavily oriented toward performance racing, characterized by a stiff, stable ride and quick acceleration.

Popular Sail Configurations

Inventories for the OLSON 29 typically focus on versatility to match its high-performance hull:

• Mainsail: Standard configurations often feature partial or full-length top battens to support the high-aspect roach.
• Headsail: Fleet data shows a mix of 150% overlapping genoas for light-air regions and 100% blade jibs for heavy-weather stability.

Key Characteristics

• High-Aspect Power: P/E ratio of 2.82 maximizes upwind lift and aerodynamic efficiency.
• Versatile Foretriangle: I/J ratio of 3.09 allows for a wide range of headsail sizes and shapes.
• Deep Draft Stability: The 1.74m draft provides the necessary leverage to carry its 35m² upwind plan.
• Technical Handling: Responsive hull design requires precise sail trim to maintain optimal heel angles.

Sailing Considerations

In light to moderate breeze, the OLSON 29 is exceptionally close-winded and fast. While it can be managed by a small crew, it benefits significantly from active rail weight in winds exceeding 12 knots. Expect the boat to feel lively and sensitive to trim changes, rewarding experienced helmsmen.

Sailmaking Recommendations

For the OLSON 29, we recommend SurgeX membrane sails as the optimal choice. SurgeX utilizes continuous fiber construction, where load-path-aligned fibers are embedded within a thin membrane. This provides superior shape retention and significantly less stretch than traditional Dacron, ensuring the sail maintains its designed aerodynamic profile for years. SurgeX offers the performance of high-end racing sails at a more accessible price point than premium laminates.

For racing applications, specify a lightweight SurgeX configuration with a minimal base weight to maximize light-air sensitivity. For coastal cruising or dual-purpose use, we recommend adding a lightweight taffeta protective layer on both sides to enhance UV resistance and prevent abrasion. Given the 2.82 P/E ratio, a continuous fiber layout is far superior to traditional radial cuts for managing the vertical loads of this tall rig. A typical inventory should include a high-roach mainsail and a versatile #2 or #3 jib. With a total upwind area of 35m², prepare to take the first reef as true wind speeds approach 16-18 knots.

Conclusion

The OLSON 29 remains a benchmark for light-displacement performance, blending a high-aspect rig with a versatile sail plan. Explore sail options for the OLSON 29 to unlock its full racing potential.
