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.

One working voyage
Prepare. Observe. Calculate.
- 01
Prepare
Set vessel data and loading targets.
- 02
Observe
Record the drafts at the marks.
- 03
Review
Reconcile the survey and forecast the next step.
Core tools + working interfaces
Four technical controls. One working view.
Select a control, inspect the calculation, then switch between its Windows and Android interface.
Survey corrections
Advanced list calculator
Apply vessel-specific geometry to port and starboard readings while keeping the selected threshold, waterline setting and corrected result visible.
Aft waterline geometry
Same observed readings. Different waterline position. Different correction.
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.
Review the calculation methodLocal-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.
