DEHLER 35 Sail Configuration Guide

Overview

The DEHLER 35, designed by Simonis/Voogd, is a sophisticated cruiser-racer engineered for speed and precision. Its design philosophy targets the performance-oriented sailor who values competitive club racing capabilities without sacrificing weekend cruising comfort.

Rig Specifications & Performance Analysis

Analysis of the P/E/I/J dimensions reveals a well-balanced, modern rig:

• Mainsail Configuration: A P/E ratio of 3.10 indicates a high-aspect ratio mainsail, providing excellent lift and efficiency for upwind pointing.
• Foretriangle Design: The I/J ratio of 3.58 is optimized for powerful headsails, accommodating both high-aspect jibs and larger overlapping genoas.
• Sail Area: With 65m² of total upwind area, the boat maintains a high power-to-weight ratio.
• Performance: The rig is clearly geared toward responsiveness and technical sailing, favoring active trim and tactical racing.

Popular Sail Configurations

• Mainsail: Owners typically utilize full-battened mainsails to maintain shape in the tall P/E 3.10 profile.
• Headsail: Common configurations range from 105% high-aspect jibs for heavy air to 135% genoas for light-wind regions.

Key Characteristics

• High-aspect rig (P/E 3.10): Optimized for superior lift and aerodynamic efficiency upwind.
• Versatile Foretriangle (I/J 3.58): Supports a wide range of headsail sizes for diverse conditions.
• Simonis/Voogd Hull (10.51m LOA): Delivers a stiff, weatherly performance with minimal heel in moderate breezes.
• Balanced Sail Plan: The 65m² total area provides a fast platform that remains manageable for small crews.

Sailing Considerations

• Effective for racing with a crew of 4-6, yet easily handled by two when cruising.
• The boat remains stiff and stable, though it requires early reefing above 18-20 knots to maintain optimal heel angles.
• Expect high performance in light-to-moderate air, where the high-aspect rig excels.

Sailmaking Recommendations

For the DEHLER 35, we recommend SurgeX membrane sails as the optimal choice for most sailors. SurgeX utilizes continuous fiber construction where fibers are laid precisely along load paths and embedded in a thin membrane. This provides superior shape retention compared to traditional Dacron while being significantly more cost-effective than premium laminates. The continuous fiber structure ensures minimal stretch over time, maintaining the designed aerodynamic profile for years of heavy use.

For racing applications, specify a lightweight SurgeX configuration with minimal base weight to maximize light-air responsiveness. For cruising or offshore work, we recommend adding a taffeta protective layer on both sides to enhance UV resistance and prevent abrasion. Given the 3.10 P/E ratio, a tri-radial fiber layout works best to handle the vertical loads of the tall mainsail. A typical high-performance inventory includes a SurgeX Mainsail, a #1 Genoa, and a reaching Gennaker. With 65m² of sail area, plan to reef the main around 18 knots to keep the boat flat and fast.

Conclusion

The DEHLER 35 is a versatile performance yacht that thrives with high-quality membrane sails. Explore sail options for DEHLER 35 to maximize your yacht's Simonis/Voogd racing pedigree.
