Hydrostatics
Calculator

The following calculator
assumes 11 equally-spaced stations and 7 equally-spaced waterlines.

LBP =

ft, DWL =

ft (If you change the design waterline DWL, the rest of the waterline
locations will be updated automatically, but not the corresponding
stations; you will need to do that manually).
