What is daggerboards?

Daggerboards are hydrofoils attached to the hull of a sailing vessel, usually a sailboat or a windsurfing board. They are used to prevent the boat from drifting sideways when sailing upwind. They work by creating a lifting force that acts in the opposite direction to the force of the wind on the sails, thus allowing the boat to sail upwind.

Daggerboards are commonly made of wood, fiberglass, or aluminum, and are attached to the hull with brackets or slots. They can be fixed or retractable, depending on the design of the boat.

Retractable daggerboards are preferred for their convenience and safety. They can be raised or lowered as needed, which allows the boat to sail in shallow waters and avoid underwater hazards.

Daggerboards are an essential component of high-performance sailboats and windsurfing boards, and their design has a significant impact on the sailboat's performance. Experienced sailors often adjust the angle and height of the daggerboard to optimize the boat's speed and maneuverability.
