Center of lateral resistance (or centre of lateral resistance), английский
The point of origin of net hydrodynamic resistance on the submerged structure of a boat, especially a sailboat. this is the pivot point about which the boat turns when unbalanced external forces are applied, similar to the center of gravity. on a balanced sailboat the center of effort should align vertically with the center of lateral resistance. if this is not the case the boat will be unbalanced and exhibit either lee helm or weather helm and will be difficult to control.
Garboard planks, английский
The planks immediately either side of the keel.
