Includes provisional estimates for AI adoption pressure and labour-market resilience. How this is measured
Confidence reflects task coverage, mapping and capability-evidence quality, and how much of the score rests on provisional inputs.
Task-level evidence
What is driving the score?
Occupation scores are built from the task mix—not a single prediction about a job title.

Where AI can do more
Routine, digitized, and highly repeatable tasks face the greatest pressure.
- Perform routine engine maintenance on motorboats, such as changing oil and filters.67
- Adjust carburetor mixtures, electrical point settings, or timing while motors are running in water-filled test tanks.67
- Adjust generators and replace faulty wiring, using hand tools and soldering irons.65
- Mount motors to boats, and operate boats at various speeds on waterways to conduct operational tests.64
Where people still matter
These tasks score lowest on automation feasibility—physical presence, judgement, accountability and real-world variability all resist end-to-end automation.

Adoption and labour-market outlook
Structural factors are kept separate from raw capability so you can see what actually resists automation. Adoption pressure and labour-market resilience are still provisional models—25% of this occupation’s replacement-risk weight rests on them.
