| Freeboard | The distance from top of the boat to the waterline (depth minus draft). |
| Draft | Vertical distance from the waterline to the baseline. |
| Moment | Force times a distance. |
| Waterplane | The plane bounded by a waterline. |
| Center of Buoyancy | The geometric center of the submerged volume of a boat through which the buoyancy acts. |
| Displacement | The amount of water a boat displaces; measured by weight or by volume |
| Station | Vertical transverse section planes. The intersections of these planes with the hull create curved lines also called _______s. In combination with buttocks and waterlines, _______s define the curvature of the boat’s hull. |
| Trim | A difference between the forward and aft drafts. |
| Simpson's Rule | A mathematical technique used in naval architecture to closely approximate areas and volumes through numerical integration. |
| Center of Flotation | The geometric center of the waterplane at the design waterline. |
