Daggerboards
Elevate Your Cat's Performance
Why Upgrade to a Single Daggerboard?
- Unmatched Windward Performance: A single large daggerboard offers greater keel area for better pointing angles and less side-slip, even in strong conditions.
- Reduced Drag: Doubling the chord while eliminating one board minimizes tip losses and improves efficiency.
- Better Handling: Light, responsive steering in all conditions, even under heavy loads.
- Optimized Design: Quiet operation, easy raising and lowering under sail, and smooth, precise engineering.
- Space Efficiency: Free up valuable room in one hull for more storage or galley space.

Installation Insights
- Placement: Position the case in either hull, usually off-center on the inboard side, with the leading edge of the board aligned with the mast.
- Case Dimensions: Adjust the case height to suit your hull design.
- Design for Comfort: Install the board in a walk-through area behind the main mast bulkhead, allowing easy movement within the hull.

The Difference You'll Feel
Upgrading to a single daggerboard changes everything. Enjoy effortless windward passages, better handling, and light steering, even in heavy weather.
