Displacement–length ratio
- Displacement–length ratio
-
The displacement–length ratio (DLR or D/L ratio) is a calculation used to express how heavy a boat is relative to its waterline length. (Rousmaniere, 1999)
A DLR is calculated by dividing a boat's displacement in long tons (2,240 pounds) by one one-hundredth of the waterline length (in feet) cubed:
The DLR can be used to compare the relative heaviness of various boats no matter what their size. DLR less than 200 indicate a racing hull, while hulls with greater than 325 indicate a heavy cruising hull.
