Multipass Voyage Tools
Crew-first tools for checking marine weather along an intended passage and organizing the information needed before preparing or reviewing the official berth-to-berth passage plan.
Practical maritime support without an enterprise contract, specialist sales process, or fleet-sized budget.
One voyage structure
Departure, destination, sailing time, speed, vessel particulars, and route points should be entered once. Voyage Weather will use them first. Passage Appraisal will later add navigational checks and company-supplied requirements to the same saved voyage.
First functional module
Check forecast wind, waves, and swell along the expected route and timeline, rather than seeing conditions only at the departure and arrival ports.
First practical question
Where and when are the most demanding forecast conditions expected along this passage?
Second module
Organize the information required before the navigating officer prepares or reviews the official berth-to-berth passage plan.
Intended role
Preparation, organization, and review support—not automatic approval and not a replacement for official navigation systems.
The port, berth, anchorage, or route position where the voyage assessment begins.
The intended arrival port, berth, anchorage, or route position.
The expected sailing time used to align forecast conditions with the vessel’s progress.
The expected average speed used to estimate when the vessel may reach each route section.
A latitude and longitude used to describe the intended route and sample forecast conditions.
The modelled date and time associated with conditions at a route point.
Safety and source boundaries
Crew-first must also mean honest limits. Multipass should explain where its information comes from, what it can assist with, and what remains the responsibility of the bridge team and official systems.
Every forecast and navigational reference must identify its source, model run, forecast time, and update time.
Multipass will not infer company-specific UKC, speed, reporting, or navigation requirements. These must be supplied from the applicable SMS, standing orders, voyage instructions, or official company publications.
Model forecasts are estimates and may change. They must be compared with warnings, observations, onboard instruments, and updated official information.
Multipass does not replace ECDIS, official charts, navigational publications, route checking, the navigating officer, bridge-team procedures, pilotage, or the Master’s approval.
Navigational limitation
Multipass Voyage Tools provide forecast interpretation, preparation, and decision support. They do not constitute an approved passage plan or navigational instruction and must not be used as the sole source for safe navigation.
