Local-first draft survey & trimming workspace

Observed by the officer. Calculated on the device.

Primarily designed for Capesize bulk carriers.

Plan draft surveys and cargo-trimming forecasts with vessel-specific corrections, expected drafts and limit checks in one local-first voyage.

Operational foundation

Accuracy begins at the draft marks.

Every draft survey begins at the marks. Accurate observed drafts—and any justified corrections—form the basis of every hydrostatic selection, displacement and cargo calculation that follows.

An error introduced at the marks carries through every subsequent result.

Local-first assurance

Core calculations stay available when the network does not.

Draft survey and trimming calculations run locally. Voyage transfer is optional and only begins when you choose it.
