Centre of Lateral Resistance

The effective point through which the combined underwater force resisting sideways motion is considered to act.

It depends on the hull, keel, rudder and their operating conditions, rather than simply the geometric centre of the underwater profile. Its relationship to the sail plan’s centre of effort helps explain balance, but heel, speed, leeway and rudder angle also affect steering behaviour.

Terms with the same meaning:
Center of lateral resistance, Centre of resistance, Center of resistance

Beam Reach

The wind is coming across the side of the boat. This is usually quick, stable, and easy to feel.
