ABOUT

Built by a mariner, for mariners

PassagePlan Pro was built by a professional mariner who spent years watching bridge officers spend hours assembling passage plans in Word documents — pulling tides, weather, port information, and hazards from dozens of separate sources, then typing it all into a template that hadn't changed in 20 years.

The data should come together. The decision stays with the master.

PassagePlan Pro is decision-support software for the IMO A.893(21) appraisal phase. It aggregates the crew's own ECDIS route with ADMIRALTY publications, tidal predictions, weather forecasts, NAVAREA warnings, port information, pilotage details, hazards, and contingency plans into a single workspace. The master reviews, edits, and signs the plan. The software does not certify it; the master does.

The product is built on real bridge experience and structured to IMO Resolution A.893(21). PassagePlan Pro does not replace official nautical charts, ADMIRALTY publications, or the professional judgement of qualified navigators — it consolidates the inputs the master uses to make those judgements. Developed by Sharp Digital Solutions Ltd.
