PlotroomWaypoints and turns
Add, insert, move, reorder, or remove waypoints. Set turn radii, geometry, asymmetric XTD, and parallel-index offsets by leg.
Plotroom capabilities
One operational picture from first waypoint to bridge handoff.
Plotroom supports the whole passage-planning sequence while keeping chart presentation, safety context, and vessel authority clear.
Chart presentation shaped for the planning task.
Plotroom draws NOAA ENC data with familiar ECDIS-style colours and symbols. Detail changes with scale and includes depths, soundings, aids to navigation, lights, hazards, routeing measures, restrictions, and charted names.
- Day, Dusk, and Night palettes are independent of the app theme.
- Choose 4-shade, 2-shade, or Unsafe depth colouring and set personal display contours.
- Use Land only transparency to reveal roads, terrain, or imagery ashore while the water chart stays readable.
- Pick a chart feature to read its attributes, survey detail, chart title and edition, and attached chart notes.
Build the route on the chart and in the leg table.
Direct chart editing and a complete leg table work together. Changes remain visible in the route geometry, XTD corridor, turn fillets, and schedule.
Times, speeds, and stops
Fix the speeds and times that matter. Plotroom solves the rest of the schedule and identifies an infeasible segment without silently changing your constraints.
Regimes and route check
Classify navigation regimes from chart depth areas and check the full XTD corridor against shallow water, land, and linked danger objects.
Dividers, VRM, and EBL
Lay familiar measuring aids over the chart. They move with direct gestures, participate in undo, and remain with the saved view.
Discussion at the right place
Attach a comment to the route, a waypoint, or a leg. The chart and table show where review attention is needed.
Passage-plan sheet
Prepare an overview, complete leg table, totals, and approval block for printing or PDF handoff.
Use the context that changes the plan.
Load the material needed for the voyage and leave the rest in the library. Each layer keeps a clear role in the chart picture.
- Reference layers: sea ice, NOAA planned surveys, survey progress, BlueTopo bathymetry, and imported BAG grids.
- Operational overlays: survey limits, look-ahead areas, notes, hazards, and other point, line, area, or circle objects.
- Vessel information: live positions and recorded ship tracks alongside the route.
- External maps: saved web map and feature services for the GIS sources the voyage requires.

⚓Positions
Return to the same planning picture.
A named view remembers the camera, loaded layers, chart presentation, depth mode, opacity, and other map settings. Switch views for different work areas, reopen one on another device, or share a temporary link with a shipmate.
- The mobile layout keeps fast ENC, basemap, depth, and chart controls above the map.
- Day and Night app themes reduce glare without changing the selected chart palette.
- Personal display-contour values follow the account while vessel safety settings remain authoritative for route checks.
Organize today's work and retain the approved record.
The Library keeps routes and supporting material available to the right people. The Voyage Log provides a ship-focused history of the passages that reached approval.
One library for every item type
File routes, overlays, rasters, web layers, and tracks in personal, ship, or fleet collections. A route filed in several places remains one controlled plan.
Find and load what the voyage needs
Search across the library, inspect an item's origin and coverage, load it into the current view, or fit the chart to it without disturbing unrelated work.
Approved passages by ship and date
Filter the Voyage Log to revisit an approved route and its legs, download RTZ or GPX for the bridge, or prepare its departure MOVREP.
Library
Show the collection structure and the breadth of material available to a voyage.
Voyage Log
Move from the approved voyage record to its chart overview and complete passage-plan detail.
A direct route from draft to approved plan.
Roles and vessel assignment determine who can prepare, review, and approve the passage. The plan and its decisions stay together throughout.
Build or import
Start on the chart or bring in an existing route, then complete its geometry and schedule.
Check
Review vessel safety settings, chart context, navigation regimes, and route-check findings.
Submit and review
The Commanding Officer reviews the plan, comments where needed, and approves or returns it.
Use the approved plan
The approved route, schedule, comments, and audit trail form the plan of record.
Carry the plan into the systems already aboard.
Plotroom preserves a high-fidelity route while supporting the exchange formats used by bridge, planning, and GIS workflows.

Navigation safety: Treat every export as a handoff for verification—not as a substitute for the certified ECDIS. Confirm geometry, schedule, alerts, and chart context on the vessel's official, corrected charts.
