Hull Deductibles on Car Carriers — The Quiet Restructuring
By Vignesh D. · April 17, 2026 · 5 min read
Headline premiums get the press. Deductible structure is where underwriters have shifted as much exposure back to the owner since 2022.
Hull and machinery deductibles on car carriers have changed shape since 2022 — not just in absolute amount but in how they apply. The premium increases get the headlines. The deductible restructuring is where a similar amount of exposure has been quietly pushed back onto the shipowner.
What changed
- Per-event deductibles have risen, often by multiples of the pre-2022 figure.
- Fire-specific deductibles have become a separate line, often higher than the standard occurrence.
- Aggregate-stop structures (the annual cap on deductibles) have widened.
- Wreck-removal and salvage are increasingly excluded from the deductible offset.
What this implies for the owner
A fire that previously cost the owner their deductible now costs them noticeably more — even if the gross hull premium looks similar to last year. The total cost-of-risk picture moves on the deductible side as much as on the premium side. Detection investments that reduce expected fire frequency act on both.
Deductible restructuring is the underwriter telling the owner: you carry more skin in the game now. Detection telemetry is one of the few levers that moves both premium and deductible negotiating posture.
