Daggerboard vs. Centerboard — What's the Difference?

Difference Between Daggerboard and Centerboard


Key Differences

Daggerboards are straight, vertically oriented fins that insert into a slot in the hull of small sailboats, providing lateral resistance and stability to prevent sideways drift, known as leeway. They are simple in design and can be fully removed from the boat when not in use or for storage and transport. Centerboards, on the other hand, are mounted within a casing in the hull and can pivot or retract, allowing for more versatility in various water depths and conditions.
The primary function of a daggerboard is to improve the sailboat's upwind performance by minimizing sideways motion, allowing for a more direct and efficient course. Due to their fixed position, when fully inserted, they are most effective in deeper waters where there is no risk of grounding. Centerboards offer a similar function but with added flexibility; they can be raised or lowered depending on the depth of the water, making them suitable for sailing in shallow waters or near the shore.
In terms of design and operation, daggerboards are straightforward, making them ideal for smaller, simpler sailboats or those used in educational settings. Their ease of use and maintenance make them a popular choice for beginner sailors. Conversely, centerboards, with their ability to retract, require a more complex mechanism within the hull, making them better suited for larger or more advanced sailboats that might encounter a wider range of sailing conditions.
Daggerboards are typically found in very small sailboats, dinghies, or certain types of racing sailboats where simplicity and weight savings are paramount. The lack of moving parts means less maintenance and fewer potential points of failure. Centerboards, due to their retractable nature, are often seen in larger leisure craft and sailboats that need the versatility to navigate both deep and shallow waters without the need to manually remove the board.
Both daggerboards and centerboards play crucial roles in the performance and handling of sailboats, yet they cater to different sailing needs and preferences. The choice between a daggerboard and a centerboard depends on the specific requirements of the sailboat, such as size, type, and the waters in which it will be sailed. Sailors must consider these factors to determine which system best meets their needs for stability, performance, and versatility on the water.

Alternative spelling of centreboard


A removable centerboard on a small sailboat that can be lowered into the water to serve as a keel


A retractable or sliding keel used on sailboats, formed of a broad board or slab of wood or metal which may be raised into a water-tight case amidships, when in shallow water, or may be lowered to increase the area of lateral resistance and prevent drifting to leeward when the vessel is beating to windward. It is used in vessels of all sizes along the coast of the United States

Common Curiosities

What is the main purpose of a daggerboard in a sailboat?

The main purpose is to provide lateral resistance and stability, minimizing sideways drift and improving upwind performance.

Is it easy to remove and install a daggerboard?

Yes, daggerboards are designed for easy removal and installation, making them user-friendly, especially for beginners.

How does the presence of a daggerboard affect a sailboat's performance?

A daggerboard improves a sailboat's upwind performance by reducing leeway and enhancing lateral stability.

Can a centerboard be fully retracted?

Yes, a centerboard can be fully retracted into its casing to navigate shallow waters or for storage.

How does a centerboard improve a sailboat's versatility?

By allowing adjustment for water depth, a centerboard enhances a sailboat's ability to sail in diverse conditions.

What types of boats typically use centerboards?

Centerboards are used in larger sailboats and leisure craft that need adaptability for sailing in varied water depths.

What are the advantages of a centerboard over a daggerboard?

The main advantage is its adjustability for different water depths, offering greater versatility in sailing conditions.

Do daggerboards require regular maintenance?

Daggerboards require minimal maintenance due to their simple design and lack of moving parts.

How does a sailor control a centerboard?

A centerboard is typically controlled by a lever or line system that allows the sailor to raise or lower it from the cockpit.

Can a sailboat have both a daggerboard and a centerboard?

Typically, a sailboat will have either a daggerboard or a centerboard, but not both, as they serve a similar function.

Are daggerboards suitable for all types of sailing waters?

Daggerboards are most effective in deeper waters and may not be suitable for extremely shallow or rocky areas.

What considerations should be taken into account when choosing between a daggerboard and a centerboard?

Considerations include the type and size of the sailboat, the sailing conditions it will be used in, and the sailor's preference for simplicity versus versatility.

Can the design of a daggerboard vary between sailboats?

Yes, while the basic principle remains the same, the size and shape of daggerboards can vary depending on the sailboat's design and performance needs.

Why might a sailor choose a boat with a daggerboard?

A sailor might choose a daggerboard for its simplicity, ease of use, and effectiveness in certain sailing conditions, particularly for small boats and dinghies.

What is the impact of a centerboard on a sailboat's draft?

A centerboard allows for a variable draft, reducing it when retracted for shallow waters and increasing it when deployed for stability.
