Useful power
Shape and area are matched to the target angles so the sail adds power where the existing inventory begins to lose effectiveness.
Performance Cruising
Asymmetrical
Spinnaker
A free-flying downwind sail shaped around the angles you want to sail, the inventory already aboard, and the handling that fits your crew.
- Primary role
- Reaching and downwind power beyond the working headsails
- Design
- Target angles and useful wind range tailored to your boat
- Handling
- Direct launch, snuffer, or compatible furling configuration
The RSD approach
Start with the gap in your sail inventory.
An asymmetrical spinnaker may add light-air reaching power, extend useful performance after bearing away, or provide a deeper-running option. RSD sets the sail’s area, fullness, luff projection, cloth weight, and handling configuration around the role it needs to cover.
Forgiving handling
The design balances performance with a usable steering and trimming range for practical Performance Cruising.
Inventory fit
The sail is specified in relation to the mainsail, working headsails, other downwind sails, crew, and deck configuration.
Sail-role variants
One sail type, designed for different jobs.
Start with the role rather than the code. Familiar A-designations are shown only as reference points; the final geometry and working range are defined for your boat.
A1-style
Light-Air Reacher
A lighter, more reaching-oriented design for generating power at closer angles in lower wind speeds.
A1.5-style
All-Purpose Asymmetrical
A broad-range option balancing reaching ability, downwind performance, and straightforward handling.
A2-style
Deep-Running Asymmetrical
More area, depth, and projection for broad angles and stronger performance farther downwind.
A3-style
Stronger-Wind Reacher
A smaller, flatter design intended to remain controlled as apparent wind and sailing loads increase.
Construction
Performance flying shape. Tough, durable construction.
Construction is selected after the sail role. RSD specifies cloth weight and reinforcement around sail area, expected loads, handling system, and intended use.
Primary construction
Cruising Nylon
Coated nylon construction delivers dependable flying shape with the durability, tear resistance, and softer handling suited to regular cruising use.
- Panel layout
- Radial panel layout aligns the cloth structure with the sail’s loads and intended flying shape.
- Why choose it
- Strong, resilient construction with a softer hand for easier handling, packing, and repeated use.
- Design selection
- Cloth weight is selected around sail area, target wind range, expected loads, and intended use.
Handling systems
Choose the handling that fits the crew.
The sail and handling system are specified together. The best solution depends on sail size, deck layout, crew, and how frequently the sail will be set and recovered.
Simple package
Direct launch
A conventional bagged sail keeps the system simple when the crew and deck arrangement support normal hoists and douses.
Controlled douse
Snuffer
A practical option for containing the sail during hoists and recoveries, particularly for short-handed crews or larger sails.
Where compatible
Top-down furling
Top-down furling can be considered where the sail geometry, luff system, and intended use support a complete purpose-designed package.
Color and graphics
Make the sail unmistakably yours.
Nylon color selections and custom graphics are developed after the sail role and construction are defined. Final availability is confirmed in your proposal.
