A swing keel is a movable keel system found on certain sailing yachts. Unlike a fixed keel, a swing keel can be raised or lowered with a hydraulic or mechanical system. This allows the yacht to adjust its draft depending on the water depth and the sailing situation.
Function and benefit:
When the swing keel is lowered, it reaches deep into the water and provides several important advantages.
• Increased stability
• Better sailing performance
• Reduced sideways drift
• Stronger resistance against heeling
When the keel is raised, the yacht gains the flexibility to enter shallow bays, sandy areas and narrow harbors. It can approach beaches more easily, cross over shallow regions and maneuver in places that deep keel yachts cannot reach.
A raised keel is especially useful when navigating lagoons, passing sandbanks, entering estuaries or anchoring close to the shore. It allows safe access to coastal areas with limited depth and gives the crew more options when choosing anchorages.
Stability and safety:
A swing keel combines the strengths of a deep keel with the advantages of a shallow draft. In stronger winds the keel is lowered to maximize stability. In calm conditions or near the coastline the keel can be raised for safe passage in shallow regions. This flexibility creates a more comfortable and secure sailing experience for guests.
Construction aspect:
A swing keel requires a more complex design than a fixed keel. It depends on a strong hinge, a reliable lifting mechanism and regular maintenance to ensure smooth operation. Because of this, swing keels are often found on performance oriented yachts that aim to balance sailing ability with shallow water access.
For guests, a swing keel offers more freedom when choosing destinations. It allows the yacht to visit quiet coves and protected areas that would otherwise be inaccessible. This adds variety, comfort and a sense of exploration to the trip.
