Making the Most of Centerboards
Rake the mast to spec. Sail the boat flat. Bear away in the puffs when sailing deep, before the boat begins to heel excessively. Always steer for balance. However, a centerboard or daggerboard adds an additional trim tool that is often forgotten. When the centerboard first begins to swing up, it moves more aft than up.
Sailboat Centerboard: Everything You Need to Know
A sailboat centerboard is a retractable keel or fin located in the center of the boat's hull. It provides stability by counteracting lateral forces from wind, allowing the vessel to sail closer to the wind. The centerboard can be raised or lowered based on water depth and sailing conditions, optimizing performance and preventing damage.
What is a Sailboat Centerboard?
A sailboat centerboard is a retractable fin that protrudes from the bottom of the hull. The centerboard keeps the boat stable and on course. Centerboards are an important and often overlooked part of a sailboat, but they're essential to stability and effective navigation. Centerboards perform the function of a keel and keep the boat on course ...
What's the deal with Centerboards?
A centerboard is a retractable appendage that pivots in and out of a slot (centerboard trunk) in the hull/keel of a sailboat. Having the ability to raise and lower the centerboard allows the the boat to operate in shallow waters when lifted, while maintaining good upwind sailing characteristics with the centerboard down.
Some Common Centerboard and Daggerboard Designs
In the case of the Seward 46RK, the daggerboard, or lifting keel, is comprised of a solid polyester composite, with a fiberglass skin and a series of stainless rods running the length of the foil to both increase stiffness and carry a 7,500lb cast-lead ballast bulb. An electric motor, operated by a set of buttons at the mast, raises and lowers ...
Centreboard
A centreboard or centerboard (US) is a retractable hull appendage which pivots out of a slot in the hull of a sailboat, known as a centreboard trunk (UK) or centerboard case (US). The retractability allows the centreboard to be raised to operate in shallow waters, to move the centre of lateral resistance (offsetting changes to the sailplan that move the centre of effort aft), to reduce drag ...
Centerboard (Swing Keel) vs. Fixed Keel: Pros and Cons
To help you out, I'll list the pros and cons of fixed vs. swing keels on sailboats in this article. Fixed keels offer better performance than swing keels and centerboards, since they are more comfortable and faster. They require less maintenance. However, swing keels offer a low draft, and are less prone to damage when running aground.
Understanding the Function of a Centerboard in Sailing
A centerboard is a retractable keel found on sailboats and other small watercraft. It is designed to provide stability and prevent the boat from drifting sideways when sailing close to the wind. The centerboard works by creating resistance in the water, which counteracts the sideways force of the wind and keeps the boat on course.
Sailboat Stability Uncensored
The Presto 30 designed by Rodger Martin is a centerboard boat that relies greatly on internal ballast and form stability to stay upright. (Photo courtesy of Thor Finn Sailing) At its most basic level, my goal as a sailor is pretty simple: keep my neck above water. Speed, comfort, progress toward a destination are nice, but if I need gills to ...
Sailboat Centerboard Upgrade
As this board was a thin flat plate, this performance was rather poor, consistent with the excessive leeway (115? tacking angles) and noticeable lee helm of the vessel. A thicker, more effective centerboard would not fit the narrow centerboard slot of the vessel.
Choosing a Centerboard or Fixed Keel Sailboat
On centerboard sailboats, the centerboard functions like a keel to keep the boat from being blown sideways. (All sailboats need a keel of the board for this reason: the narrow, flat surface of the board or keel produces little drag when the boat moves forward but resists motion sideways.)
A Short List of Centerboard Cruising Boats
Ive sailed on a couple of these sloops and like the way they look and sail. The boats heritage gives it a loyal following (a good thing to look for in any used boat). Pros: Storied design, with a good deck layout and comfortable motion. Cons: Finish quality varies greatly as many were owner-completed. Factory interior is pretty basic. 3. Tartan ...
Centerboard VS Daggerboard The Differences Explained
On a sailboat, the difference between a daggerboard and a centerboard is how they are moved into position. A daggerboard is lifted and raised vertically (up and down) through a slot in the hull; a centerboard, on the other hand, pivots or swings into place. That was the short answer.

It folds out like a pocket knife and allows you to increase or reduce the draft of the boat. Centerboards are mostly used on small fishing boats. The centerboard is a very versatile keel type, allowing you to have both a very shoal draft for inland waters, as well as steadying the boat and reducing heel for larger bodies of water, or even oceans.

Daggerboard
When a small sailboat flips on its side, the keel can also be used to right the boat. Standing on the keel gives the sailor additional leverage to roll the hull upright. The centerboard, daggerboard, or bilgeboard can be used as a platform upon which to stand, providing increased leverage, in the event the dinghy overturns via a capsize or turtle.
Centerboard/Daggerboard Placement
John Teale's book on boat design suggests a 5-6% lead for heavy displacement hulls. (5-6% of the LWL between the center of effort and the center of lateral resistance) For lightweight hulls this can be stretched out to 14-15%. Of course with a centerboard, your given a little leeway as raising a hinged centerboard moves the center of effort back.
Sailboat Keel Types Compared: Pros and Cons of 13 Types
Reduced interior space: Depending on your sailboat's design, the presence of a centerboard trunk may limit the available interior space, impacting your comfort and storage options. Swing Keel The swing keel is a type of sailboat keel that essentially pivots on a hinge or bolt, allowing the keel to swing up or down as needed.
Best Centerboard Designed Boats
I think the keel/centerboard designed, as mentioned above, is the best CB configuration. This design is used by Hinckley, Bristol, Little Harbor, Cheoy Lee (Pedrick 41) and Alden to name just a few builders. Many K/CB boats can be sailed equally as well with the board up as down, on almost all points of sail.
New J/95 Centerboard Sailboat is Fit for Shallow Water
Although we could point the boat slightly higher with the 200-pound centerboard lowered, the most noticeable effect of lowering the board was a stiffer ride and a reduced angle of heel. Conclusion. Given the anemic state of the new sailboat market, J/Boats initially expected to sell one J/95 a month until buyers hopped off the fence.
