Formula

Boat Speed = ( DT / TT / 60 )

Where,

DT is Distance Travelled

TT is Time Travelled

Displacement Speed (or) Hull Speed Formula

Hull speed or displacement speed is the speed at which the wavelength of a vessels bow wave is equal to the waterline length of the vessel.

Where,

LWL is is the length of the waterline in feet

vhull is the hull speed of the vessel in knots
