Planning estimate, not navigation
This distance is computed over the open Eurostat shipping-lane network. It is a realistic passage length for planning, but your sailed distance will differ with weather routing, currents, draft, and the exact berths you leave from and arrive at. Always verify against official charts.
Plan this passage properly
Open Cape Town to Santos in the Marine OS route planner: it suggests the sea route, then you drag waypoints, set your speed and fuel burn, and check weather and tides along the way.
