as usual dennisb I have forgotten the most important part.
If we want to define a point in space that has no length breath or depth its position relative to the zero point can be defined my its x,y.z coordinates.
But a boat has length breath and depth so we need many coordinates to define its shape, to do this we need a grid. The grid is made up of the Stations (X coordinate), Buttocks (Y coordinate) and Water lines (Z coordinate). Where these planes intersect gives us its XYZ position on the surface of our hull. These positions are listed in what is called a Table of Off-Sets. Because our hull is symetrical we only need the off sets from one side of our hull. With out the off-set table the hull can’t be built.
