In sailing, the primary force that propels a sailboat forward is the wind. The sails of the boat are designed to capture the wind's energy and convert it into forward motion.

In sailing, the term 'heel' is used to describe the angle between the sailboat's hull and the waterline. It refers to the boat's inclination to one side due to the force of the wind on the sails.

Sculling is a rowing technique where the oars are moved alternately, with one oar in the water and the other in the air. This technique is commonly used in recreational rowing and certain competitive events.

In rowing, the term 'blade' refers to the part of the oar that is submerged in the water during the rowing stroke. It is designed to provide propulsion and maneuverability to the boat.

Tacking is a sailing maneuver where the sailboat is turned into the wind, causing the sails to luff and lose power. This maneuver is used to change the boat's direction and to sail upwind.

In sailing, trimming refers to the process of adjusting the sails to optimize their performance. It involves adjusting the angle of the sails to the wind and ensuring proper tension to maximize efficiency.

Sweep rowing is a rowing technique where both oars are moved simultaneously, with both oars in the water. This technique is commonly used in competitive rowing and requires coordination and synchronization among the rowers.

In sailing, the keel is the part of the sailboat that extends underwater and provides stability. It helps prevent the boat from capsizing and provides directional control.

Gybing is a sailing maneuver where the sailboat is turned away from the wind, allowing the sails to fill with wind and gain power. This maneuver is used to change the boat's direction and to sail downwind.

In sailing, reefing refers to the process of reducing the sail area on a sailboat to make it more manageable in strong winds. It involves partially folding or rolling up the sails to reduce their size.

Outrigger rowing is a rowing technique where a single oar is used, with the rower facing the direction of travel. The oar is attached to an outrigger, which is a long, narrow float that provides stability to the boat.

In sailing, the rudder is the device used to steer the sailboat. It is a flat, underwater surface that is attached to the stern of the boat and is used to control its direction.

In sailing, anchoring involves dropping an anchor into the water to secure the boat in a specific location. It is used to stop the boat from drifting and to provide a stable platform for various activities.

In sailing, hoisting refers to the process of raising the sails on a sailboat. It involves pulling the sails up the mast using ropes and pulleys.

Coxed rowing is a rowing technique where two oars are used, with the rower facing away from the direction of travel. The rower sits in a coxswain's seat at the stern of the boat and uses a tiller to steer.
