Nautical charts and navigation instruments laid out for study

Key takeaways

  • Identify whether a position is observed, reported or forecast.
  • Confirm open dates through the appropriate commercial channel.

Separate three kinds of position

Use distinct fields for the observed location, the expected next movement and the proposed commercial opening. These fields may describe different times and should not overwrite each other.

  1. Preserve the observation timestamp and source.
  2. Label predicted movements as forecasts with their assumptions.
  3. Request confirmation of availability before making a commercial proposal.

A ship near a loading area may still be occupied with its current employment. Conversely, a vessel farther away may have a confirmed schedule that suits the requirement. The shortlist needs both location and contractual availability information.

Common mistakes

Do not interpret a stationary position as proof that a ship is idle. Avoid turning a forecast arrival into a confirmed open date. If data sources conflict, show the discrepancy rather than silently selecting the most convenient result.

Frequently asked questions

Is a position list the same as a tonnage list?

They can overlap, but location information and commercial availability answer different questions.

Does an observed position predict the next fixture?

No. It describes location, not the owner's future employment decision.

Why retain old observations?

They can help reconstruct changes and evaluate a forecast's basis.

Which field needs commercial confirmation?

The opening position and date proposed for the next employment.
