Free Sea Distance & Transit Time Calculator: Port to Port & Multi-Leg Voyages

Calculate shipping distance and marine transit time between ports along real shipping routes — a free sea distance and transit time calculator for port-to-port and multi-leg voyages. Add as many stops as you need, no login or account required. It also works as a cargo ship distance calculator: pick a vessel type to estimate CO₂ emissions for bulk carriers, container ships, tankers, and more on the same route.

Routes are generated for visualization and voyage appraisal, not for actual ship navigation.
