Expedition is the best pick for crews who need chart-aligned planning plus portable plan review because its file-based route and waypoint exchange workflow keeps your navigation objects consistent across setups, while TimeZero is a strong alternative for captains who want chart-layer route planning tied directly to iterative waypoint edits and track review.
Editor’s top 3 picks
Three quick recommendations before you dive into the full comparison below — each one leads on a different dimension.
Expedition
Expedition’s file-based route and waypoint exchange workflow keeps planning objects portable across navigation setups.
Best for: Fits when crews need chart-backed route planning plus track-based plan review across devices.
TimeZero
Editor pickRoute planning that stays tied to chart layers, then feeds iterative waypoint edits and track review without breaking workflow.
Best for: Fits when captains need structured route planning, waypoint editing, and track review with chart context.
C-MAP
Editor pickChart coverage is delivered as licensed chart data with update management centered on chart preparation and governance.
Best for: Fits when organizations need disciplined chart licensing, frequent chart updates, and consistent waypoint and route workflows across onboard devices.
Comparison Table
Expedition
vertical specialistMarine navigation and performance software for offshore sailing and racing.
Expedition’s file-based route and waypoint exchange workflow keeps planning objects portable across navigation setups.
Expedition’s core workflow centers on building routes and organizing waypoints, then validating plans through track recording playback. It supports importing and exporting route data for cross-device exchange, which matters when crews use different navigation hardware. The chart display is built to align planning objects with what crews see at the helm, so review and iteration happen in the same environment.
A key tradeoff is that Expedition’s automation and governance surface depends heavily on workflow discipline because the integration points are mainly file-based and feed-based rather than centrally managed. Expedition fits best on multi-day trips where routes need to be generated before departure and verified against recorded track history, then handed off to another device for execution.
- +Strong route and waypoint editing with repeatable exchange workflows
- +Chart display designed to keep planned objects aligned with navigation context
- +Track playback supports plan review against recorded movement history
- +Works with common marine feed formats for overlay-style monitoring
- –Feed setup requires configuration discipline for consistent positioning overlays
- –Automation controls are limited compared with highly API-first navigation stacks
- –Some advanced workflows rely on manual import and export steps

- +Chart planning and route preparation stay inside one navigation workspace
- +Track recording supports post-trip review against planned routes
- +Waypoint and route asset editing supports iterative passage changes
- +Configurable chart layers help keep navigation context readable
- –Initial chart licensing and datum choices add setup overhead
- –Advanced automation requires more planning than basic point-to-point use
- –Some data exchange steps are easier with file-based workflows than live feeds
- –Onscreen density can get high when multiple overlays are enabled
