Forces on a boat
Key to making a boat go faster is to increase the thrust and reduce the dragSlide3
Displacement Hull Speed
Maximum Hull Speed
Maximum hull speed (in knots) = 1.34 x the square root of the waterline length (in feet)

Upthrust
= weightSlide5

Planing
Upthrust
+ lift = weightSlide8
Thrust constant – drag isn’t!Slide9
Sailboats can plane too!Slide10
HydrofoilsSlide11
This boat has no hull!
Lift from foils = weightSlide12
