BASHFORD (SYDNEY) 36 Sail Configuration Guide

Overview

The BASHFORD (SYDNEY) 36 is a high-performance racer-cruiser designed by Ian Murray for competitive club racing and offshore regattas. Built by Bashford Howison, this model focuses on agility and speed, making it a favorite for sailors who prioritize a responsive and weatherly hull.

Rig Specifications & Performance Analysis

• Mainsail Configuration: A P/E ratio of 2.83 indicates a high-aspect-ratio rig, optimized for aerodynamic efficiency and lift during upwind beats.
• Foretriangle Design: The I/J ratio of 3.53 is designed to support powerful headsails, typically accommodating large genoas or high-performance working jibs.
• Sail Area: A substantial 62m² total upwind area provides a strong power-to-displacement ratio for its 10.97m length.
• Performance: The rig is balanced for competitive racing while maintaining enough stability for fast coastal cruising.

Popular Sail Configurations

• Mainsail: Usually configured with a high-modulus membrane construction; full battens are common for racing durability and shape control.
• Headsail: Inventory typically includes a range of overlapping genoas and non-overlapping jibs to suit specific wind gradients.

Key Characteristics

• High-aspect mainsail (P/E 2.83) delivers superior lift-to-drag ratios.
• Versatile foretriangle (I/J 3.53) allows for diverse headsail inventories based on local conditions.
• 3.41m beam provides a stable platform that remains stiff in moderate breezes.
• Precision rig dimensions support highly technical sail trimming for competitive advantages.

Sailing Considerations

• The high-aspect rig requires active backstay and traveler adjustments to effectively de-power as wind speed increases.
• Requires a skilled crew of 6–8 for full competitive racing to manage the 62m² upwind sail plan.
• Performance is exceptional in light-to-moderate air, though the boat remains close-winded in heavy weather.

Sailmaking Recommendations

For the BASHFORD (SYDNEY) 36, we recommend SurgeX membrane sails as the optimal choice. 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 remaining more cost-effective than premium carbon laminates. The continuous fiber structure ensures minimal stretch over time, maintaining the designed aerodynamic profile for several seasons.

For racing applications, specify a lightweight SurgeX configuration with a film/film finish to minimize weight aloft and maximize acceleration. For cruising or dual-purpose use, add a taffeta protective layer on one or both sides to enhance UV resistance and abrasion protection during tacks. Based on the 2.83 P/E ratio, a full membrane layout is most effective at handling the high vertical luff loads. A typical inventory includes a high-aspect mainsail and a versatile No. 2 jib. With 62m² of sail area, plan to take the first reef at approximately 18–20 knots of true wind.

Conclusion

The BASHFORD (SYDNEY) 36 offers a refined balance of racing power and design efficiency, particularly when paired with a high-modulus sail plan. Explore SurgeX membrane sail options to maximize the performance potential of your BASHFORD (SYDNEY) 36.
