About This Tool
The Parabolic Curve Calculator is a tool for designers and builders to generate the coordinates for a perfect parabolic arc. Unlike a simple circle, a parabola's curvature changes, creating a shape many find more aesthetically pleasing for elements like deck camber or cabin tops. By defining the width and height of the desired curve, this tool provides a table of offsets that you can plot to create a perfectly fair line for your project.

Key Concepts:

Parabola: A U-shaped curve where any point is at an equal distance from a fixed point (the focus) and a fixed straight line (the directrix).
Deck Camber: The curvature of a deck from side to side, designed to shed water and add strength.
Offsets: A series of coordinates used to plot points and define a curve.
Fairing: The process of smoothing the curves of a hull or other component to ensure there are no bumps or hollows.
