Search & rescue drift modelling

Search and rescue drift modelling that narrows the search area

MarCast provides search and rescue (SAR) drift modelling that predicts where a person or object lost at sea will travel under the influence of wind, current and leeway — helping coordinators focus the search area and save time when it matters most.

What we model

SAR drift modelling built for speed

Leeway & drift prediction

Model how persons-in-water and drifting objects move under combined wind, current and leeway forces.

Search area definition

Generate probable drift areas to focus search assets and reduce time to locate.

Real-time updates

Re-run as the operation develops and as fresh wind and current forecasts arrive.

Trajectory mapping

Produce clear, shareable maps for coordination across response teams.

Metocean-driven

Driven by coupled ocean and atmospheric data for sharper predictions.

Operational outputs

Export maps and outputs to support coordination and after-action review.

Common questions

Frequently asked

What is search and rescue drift modelling?

SAR drift modelling predicts the likely drift of a person or object lost at sea using wind, current and leeway data, producing a probable search area to focus rescue efforts.

What is leeway in SAR modelling?

Leeway is the movement of a floating object caused directly by wind acting on the part of the object above the water, and it is a key factor in accurately predicting drift.

How quickly can a drift scenario be run?

Scenarios are designed to be set up and run rapidly so the search area can be defined and updated during a live operation.

Do you provide SAR modelling as software or consultancy?

Both — run drift models yourself through the software, or have our team deliver the analysis using the same validated engine.
