The helm is the person responsible for steering the sailboat and making navigational decisions.

Sailboats rely on the power of the wind to catch their sails and generate forward motion.

Sheets are the ropes used to adjust the angle and position of the sails, allowing the sailor to control the boat's movement.

The keel is a weighted structure that extends below the hull of a sailboat, providing stability and preventing it from capsizing.

Halyards are the ropes used to hoist and lower the sails on a sailboat, allowing the sailor to adjust the sail area and trim.

Running is the point of sail where the wind is directly behind the boat, allowing for maximum speed and downwind sailing.

Cleats are the fittings on a sailboat used to secure and hold ropes, including the sheets and halyards, in place.

The rudder is a flat, underwater surface that is used to steer a sailboat, allowing the sailor to change direction and maintain course.

Sheets are the ropes used to adjust the angle of the sails on a sailboat, allowing the sailor to control the boat's speed and direction.

Close-hauled is the point of sail where the wind is directly in front of the boat, requiring the sails to be trimmed tightly to minimize drag.

Lines are the general term for the ropes used on a sailboat, including those used for docking, mooring, and securing equipment.

A centerboard or daggerboard is a retractable blade that extends below the hull of a sailboat, providing lateral resistance to prevent capsizing.

Beam reach is the point of sail where the wind is perpendicular to the boat, allowing for efficient sailing and maximum speed.

Sheets are the ropes used to control the angle of the boom on a sailboat, allowing the sailor to adjust the sail shape and trim.

Broad reach is the point of sail where the wind is at a 45-degree angle to the boat, allowing for fast and comfortable sailing.
