Questions officers ask
How do I convert a route for a Transas (Navi-Sailor) ECDIS?
Open the route in NaviBoss (import any of 35 route formats, or plan it there), choose Export, pick the Transas (Navi-Sailor) format (Transas TSH .rt3, Transas iSailor .rt4 or Navi-Sailor Data Tool (CVT) .cvt) and save it to a USB stick. Then load it with your ECDIS's own route import function, as its manual describes.
Can I convert a route from another ECDIS make to Transas (Navi-Sailor)?
Yes. Import the route file from the other system (for example JRC, Furuno, Kongsberg or an RTZ file) and export it as Transas (Navi-Sailor). Importing is free; exporting needs a plan after the 7-day trial.
Does a Transas (Navi-Sailor) ECDIS take RTZ?
RTZ (IEC 61174) is the standard route exchange file and many current ECDIS models import it. Whether yours does depends on the model and software version: check its manual. NaviBoss exports RTZ as well as the Transas (Navi-Sailor) formats.
How sure is NaviBoss that the Transas (Navi-Sailor) files load?
Each format says it plainly: Transas TSH: not checked yet, Transas iSailor: not checked yet and Navi-Sailor Data Tool (CVT): not checked yet. If you have a file your Transas (Navi-Sailor) unit wrote, send it and we check the format against it.

NaviBoss guides are written and checked by maritime industry experts, masters and deck officers. Each one is built from the same data the planner uses, dated, and rebuilt when that data changes. Spotted something wrong? Tell us on the feedback board.
A planning aid, not for navigation. Always check an imported route on the ECDIS against the official charts before you use it.
