what's under the hood

Every number here comes from somewhere you can check.

7,598 Ports & charted positions

Searchable by name or UN/LOCODE.

953 Blockable canals & straits

Canals and straits you want to pass or avoid. Block one and the route re-plots with the exact difference in nautical miles.

58 Risk & regulatory zones

ECA, MARPOL Special Areas, PSSA, Piracy HRA, war-risk, warlike, VRA and transit corridors.

96,424 Waypoints

Curated professional shipping lanes — routes are shortest-path over real lanes.

Currents are Copernicus GLORYS12 monthly climatology; forecasts are NOAA GFS and GFS-Wave; coastlines are Natural Earth. A planning tool — not for navigation.

whoever you are on the voyage

Made for both onboard and shore team

officer of the watch

Appraisal means opening the routing publications, the sailing directions, digging through years-old files on the ship's PC or your laptop, or asking other officers if they have the same route — just to get a distance and the first waypoints down.

2 hours+ → seconds
master

“Captain, revert immediately distance & ETA if we avoid the Panama Canal?” The office wants it now, and your navigation officer is resting.

Wake the OOW → answer it yourself
shore ops & chartering

Every estimate waits on the vessel to reply. Then piracy areas are in one PDF, ECA limits in another and additional-premium areas on a third screen.

Half a day of email → instant answer while on call
what you get

One search draws the route. Then it keeps answering.

route intelligence

The recommended route, not a straight line on a map.

Routing follows a curated network of professional shipping lanes.

  • Per-leg and total distance in nm, ETA at any speed
  • Set the ETA and get the speed, or the speed and get the ETA
  • Drag the track anywhere to add a via-waypoint; it rebuilds instantly
  • Drifting at sea? Start the route from your current position
  • Need a stopover at Cape Town? Add a stop anywhere on the chart

alternative routes

Don't want Suez or Panama? Block it.

The alternative appears instantly — with the exact distance difference in nautical miles, before you commit to anything.

  • 953 canals & straits, blockable with one tap
  • Hover a chokepoint to preview the reroute as a ghost line
  • The difference of every avoidance, in nm
security & environment

Know every zone before you enter it.

Different zones across various categories, with the exact miles your route transits inside each one.

  • Piracy HRAs, war-risk and advisory areas — current industry designations
  • ECAs, MARPOL special areas and PSSAs from official IMO coordinates
  • Currents overlay and one-click minimum-time routing optimisation

how it works

Three easy steps.

Nothing to install, nothing to configure.

1
Search

Type your departure and arrival ports — by name or UN/LOCODE — and add stops if the voyage needs them. Or start from coordinates in the middle of the ocean and enter your destination.

See

The recommended route, distance and ETA appear instantly. Adjust speed, block a canal, check which piracy or ECA zones you cross and how far you run inside each.

Ship it

Export straight into your ECDIS or chartplotter — 35 formats covered — or send a link that reopens the exact voyage — ports, avoided passages, speed and ETD — on someone else's screen.

who it's for

One tool, for onboard team and for shore personnel.

Who will benefit from this app.

Get a distance and first waypoints at the appraisal stage at sea
Answer “what if we avoid Panama Canal?” at seaashore
Second-check a route or an ETA independently of the plan on the bridge at sea
Give a quick voyage estimate while the charterer is still on the phone ashore
Check which piracy, war-risk or ECA zones a trade actually crosses at seaashore
Compare via-Suez against via-Cape against a current-optimised track ashore
Send someone the exact scenario instead of a screenshot of it at seaashore
Get the same numbers fleet-wide and send them to your ships ashore

faq

Fair questions.

data & sources

Where do the routes and data come from?

Routing follows a curated network of professional recommended shipping lanes. Ports come from the NGA World Port Index plus terminal data, with UN/LOCODEs from the UNECE registry. Security and environmental zones are built from official IMO instruments — MARPOL Annexes, special areas and PSSAs — plus current industry piracy designations. Currents are Copernicus GLORYS12 ocean-model climatology.

How current are the zones?

The zones are rebuilt from the published coordinate tables, such as IMO circulars or industry publications.

export & accuracy

Will my ECDIS accept the export?

Yes. NaviBoss exports to 35 route formats — RTZ, GPX and every major ECDIS/chartplotter dialect (Furuno, JRC, Kongsberg, Sperry, Transas, Wärtsilä, SIMRAD, Raytheon, SevenCs, MaxSea, TOTEM, Chart Pilot and more), both directions. Load the file and your waypoints are inside your system.

How accurate are the distances?

Legs are true distances over the lane network, not straight lines on a Mercator chart.

Is this approved for navigation?

No. NaviBoss is a passage-planning and voyage-estimation aid. The routes derive from professional recommendations, but they are for informational purposes only and must never replace official charts, publications or your own navigation.

commercial

What does it cost?

The planner is free forever — no sign-up, no card, no expiry. Your first 7 days include everything; after that, exporting to your ECDIS and keeping more than one saved voyage need a plan, at $12 a month or $97 a year.

Does it work on slow ship internet — or offline?

On slow internet, yes: after the first load everything runs in your browser with no server round-trip. A fully offline desktop edition is built and running, but it is not on sale yet — there is a waitlist under Pricing.
