That's an interesting question. There are different types of keels that have different advantages and disadvantages depending on your sailing goals and preferences. Here are some pros and cons of a stub keel with a centerboard versus a fin keel:
- A stub keel with a centerboard allows you to adjust the draft of your boat by raising or lowering the centerboard. This can be useful for sailing in shallow waters or beaching your boat. A fin keel has a fixed draft that limits your access to some areas.
- A stub keel with a centerboard may have less performance than a fin keel, especially when sailing upwind. A fin keel offers better lateral resistance and stability, which translates into higher speed and less leeway. A stub keel with a centerboard may also create more drag when the centerboard is down.
- A stub keel with a centerboard requires more maintenance and complexity than a fin keel. You need to operate the mechanism that controls the centerboard, which may involve ropes, pulleys, winches, or hydraulics. A fin keel is simpler and more robust, as it is bolted to the hull.
- A stub keel with a centerboard may take up some space inside the boat, depending on how the centerboard is stored when raised. A fin keel does not affect the interior volume of the hull.
As you can see, there is no definitive answer to which keel type is better. It depends on your sailing style, preferences, and needs. Some sailors prefer the versatility and shallow draft of a stub keel with a centerboard, while others prefer the performance and simplicity of a fin keel.
