The game
Rhumbline is a free demo of an age-of-sail trading game. Take the helm of a small caravel in Seville and set out across a world built from real elevation data: the coasts of Europe, Africa, the Americas and Asia, with dozens of historical ports to visit.
Sail by the wind
Regional and seasonal winds (trade winds, monsoons, the levante and the poniente) decide your route. Trim your sails, tack upwind and read the sky.
Living weather
Calm seas, fresh breezes, gales and thunderstorms, with rain, fog, lightning and a full day and night cycle under the stars.
Trade
Dock in port, check the market, buy cheap and sell where goods are scarce. Every port has its own culture, architecture and produce.
Realistic distances
A crossing from Seville to Havana takes weeks of in-game time, compressed so the voyage still feels like one.
This is an early demo, single-player, no account or server needed. Feedback is very welcome! Windows 10/11 and Linux x86_64; a dedicated GPU is recommended.
