The case study.

The problem
Sail trim, reefing and apparent wind are hard to grasp from a book, and time on the water to practise is limited.
Who it is for
Beginners, crew joining their first races, and sailing clubs that teach them.
How it was built
A three.js simulator in the browser, built around the 3D model of S/Y Astarte: theory chapters, practical mini-games and free sailing, in English and Greek, with no account and no tracking. Designed and coded with AI coding agents.
