Shape
How much curve the rail line has from the widepoint out to each end. Straighter rails hold a line with less steering effort; curvier rails turn with less resistance.
Straighter railsCurvier rails
The board's maximum width. Wider is more stable side-to-side; narrower is faster and more efficient but demands better balance.
NarrowerWider
The shape of the front end. Rounder and fuller planes on top of the water for stability; pointier slices through it for glide and speed.
Rounder nosePointier nose
The shape of the back end. A squared tail sheds water quickly for sharp, stable turns; a round/pin tail releases water gradually for smooth, tracking turns.
Round tailSquared tail
How much the hull curves upward toward the nose and tail. More rocker rides over chop and waves without diving in; less rocker is faster and more efficient on flat water.
FlatterMore rocker
How the rocker curve is split between the nose and tail. Nose-biased adds lift up front for chop and swell; tail-biased adds a looser, easier-turning tail.

Size
The board's overall length. Longer tracks straighter and holds more speed over distance; shorter is easier to turn and easier to store or carry.
6'0" (shortest) — 14'0" (longest). Scales the board's overall size — doesn't change its shape.
The board's overall thickness. More thickness adds volume and float (higher weight capacity) without changing the outline shape.

Export
The JSON export is the source-of-truth design record — the future manufacturing-spec exporter will read from it, not from the 3D preview.

3D preview needs to load its files over a local web server — opening this page directly as a file:// URL blocks it. It works once this site is hosted (see the project README).
