TARTAN 3500 Sail Configuration Guide

Overview

The TARTAN 3500, designed by Tim Jackett, is a sophisticated performance cruiser blending traditional aesthetics with modern hull dynamics. It targets the quality-conscious sailor seeking a balance of offshore capability and responsive club racing performance.

Rig Specifications & Performance Analysis

• Mainsail Configuration: A P/E ratio of 2.90 indicates a tall, high-aspect rig designed for upwind efficiency.
• Foretriangle Design: The I/J ratio of 3.42 suits versatile headsail inventories, from large overlapping genoas to high-efficiency jibs.
• Sail Area: 57m² total upwind area provides a healthy power-to-weight ratio for light to moderate conditions.
• Performance: The configuration favors a weatherly boat that excels in close-hauled performance and light-air responsiveness.

Popular Sail Configurations

• Mainsail: Typically configured as a full-battened main to support the high-aspect leech and ensure easy flaking.
• Headsail: Most owners utilize a 135% furling genoa for all-around cruising or a 100% working jib for heavy-weather stability.

Key Characteristics

• High-aspect mainsail (P/E 2.90) optimizes lift-to-drag ratios for superior pointing.
• Large foretriangle (I/J 3.42) allows for powerful headsails in light air.
• Shallow 1.51m draft provides excellent versatility for coastal cruising and gunkholing.
• 57m² sail area ensures the boat remains lively even in sub-10 knot wind ranges.

Sailing Considerations

• The 3.63m beam provides significant form stability, making the boat relatively stiff in a breeze.
• Typical crew requirements range from a couple for cruising to a team of five for competitive racing.
• Expect a well-balanced helm with predictable performance across most wind angles.

Sailmaking Recommendations

For the TARTAN 3500, 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. For cruising or bluewater sailing, add a taffeta protective layer on both sides to enhance UV resistance and abrasion protection. Based on the 2.90 P/E ratio, a tri-radial fiber layout works best to handle the vertical loads of this tall rig. A typical inventory includes a 27m² full-batten mainsail and a 30m² furling headsail. With 57m² of sail area, plan to reef the mainsail around 16 knots to maintain optimal heel angles.

Conclusion

The TARTAN 3500’s high-aspect rig and balanced hull design make it a standout performer in the 35-foot class. Explore sail options for TARTAN 3500 to maximize your boat's speed and longevity.
