I created a virtual sailing navigation simulator that uses real-world geographic and near-real-time weather/ocean data. It also has the ability to let you set up races to play against others.

I've posted it here on HN a long time ago before [0], but I've made a large number of updates (with the help of some others as well!) since then that I thought might be worth showing again:

- released source code: https://8bitbyte.ca/sailnavsim/code.html

- created API for status/control of boats: https://8bitbyte.ca/sailnavsim/api/

- added different boat "types" to sail: https://8bitbyte.ca/sailnavsim/wind_response/

- celestial navigation mode: https://8bitbyte.ca/sailnavsim/help.html#celestial-nav-mode

- "live" mode on the maps page (using a WebSocket)

I hope you enjoy!
