P&I vs Marine Hull Insurance – Which Does a Shipowner Need?
A hull policy on your vessel does not mean third-party claims against you are covered. Here is the difference.
The Misconception: "My Hull Policy Covers Everything"
Many shipowners assume one vessel policy handles every incident. After an accident there are two separate questions: who pays for damage to my vessel? and who pays the claims others make against me? Marine Hull answers the first. P&I answers the second.
Marine Hull: Protecting Your Vessel
Marine Hull pays for physical loss of or damage to the vessel, such as hull, machinery, and equipment lost to grounding, fire, or sinking. The money goes to the shipowner. Hull policies usually include collision liability to other ships, but typically only in part (three-quarters under common standard clauses) and only for collisions with other vessels.
P&I: Protecting Against Claims by Others
P&I insurance covers the owner's or operator's legal liability to other parties: crew, passengers, cargo owners, pier owners, and those affected by pollution. The money flows to the injured third party, not to the shipowner.
Side-by-Side by Incident
| Incident | Marine Hull | P&I |
|---|---|---|
| Crew member injured during towing | Not covered | Covered (liability to crew) |
| Barge hull damaged by grounding | Covered | Not covered |
| Your vessel strikes another vessel | Your own vessel's damage, plus part of collision liability | Remaining collision liability and other resulting claims |
| Pier or jetty struck | Usually not, unless the clause is extended | Usually covered |
| Oil spill from the vessel | Not covered | Covered (pollution liability) |
| Customer's cargo damaged in carriage | Not covered | Covered (carrier's liability) |
This is a general guide. Final outcomes follow the policy wording, limits, and exclusions.
One Incident, Two Policies at Work
Picture a barge under tow striking a jetty while berthing. The barge hull is dented and a crew member is hurt. Repairing the barge is a hull claim. Compensation to the jetty owner and the crew member's medical costs are P&I claims. Without P&I, the owner pays those last two bills from company cash.
Who Needs What?
Hull only can be enough where the vessel carries no third-party crew or cargo and no charterer requires more, but that is uncommon.
Hull and P&I is the usual setup for commercial vessels: tugboats, barges, cargo ships, ferries, and OSVs.
P&I only may apply where someone else insures the vessel's value but operating liability still sits with you.
