Understanding Leeboards: A Guide to Sailboat Performance and Stability

Leeboard is a type of sail that is mounted on the side of a sailboat, perpendicular to the wind direction. It is used to provide additional lift and stability to the boat, particularly when sailing upwind or in light wind conditions.

Leeboards are typically mounted on the leeward side of the boat, opposite the wind direction, and are designed to be deployed when the boat is sailing close-hauled or beating into the wind. When the sail is deployed, it creates a force that pushes the boat towards the wind, allowing it to make progress upwind.

Leeboards can be either fixed or adjustable, and they can be controlled manually or through an automated system. They are commonly used on smaller sailboats, such as dinghies and day sailors, but they can also be found on larger boats and even on some catamarans and trimarans.

Overall, leeboards are a useful tool for sailors looking to improve their boat's performance and stability in certain sailing conditions.
