Hull Speed Max Formula
HS = 1.34 × √LWL (in feet)
The maximum speed of a displacement hull (referring to a hull that travels through the water rather than on top of it, e.g. planing).

Pounds per Inch Immersion Formula
PPI = LWL Area × 5.333
The weight required to sink the yacht one inch. Calculated by multiplying the LWL area by 5.333 for sea water or 5.2 for fresh water.
