Protection and Indemnity insurance is a marine liability policy designed for the specific legal and operational realities of operating a vessel. It originated in the 19th century as mutual insurance among ship owners — owners pooling money to cover the liabilities they all faced — and the structure has carried forward into modern marine insurance. Today, P&I is written either as a standalone policy (for commercial vessels and large yachts) or bundled into yacht-form and marine package policies as the liability component.
P&I is broader than auto-style or general liability coverage in three meaningful ways:
It covers maritime law exposures that land-based policies do not contemplate. The Jones Act, Longshore and Harbor Workers' Compensation Act (USL&H), Death on the High Seas Act, and general maritime law create employer and operator liabilities that no commercial auto or general liability policy will respond to.
It covers vessel-specific liabilities — wreck removal, fuel spill, pollution, towage, and salvage — that are part of operating any boat in the water but outside the scope of any non-marine policy.
It is written on a marine policy form — by underwriters who actually know marine, with brokers who understand the difference between a boat at a slip and a boat under tow. Generic carriers do not write meaningful P&I capacity.
Who Needs P&I Insurance?
P&I is the marine liability backbone for:
- Yacht owners — bundled into the yacht-form policy as the protection and indemnity component
- Charter boat operators — bareboat, crewed, and term charter
- Commercial fishing operators — commercial trawlers, longliners, lobster, and shrimp boats
- Tugboat and towing operators — including assistance towing, salvage, and harbor towage
- Marine contractors — dredgers, pile drivers, marine construction
- Workboat operators — supply boats, crew transfer, dive boats, research vessels
- Marina operators with workboats or service vessels — separate from the marina liability policy
- Offshore oil and gas service vessels
- Passenger vessel operators — ferries, tour boats, dinner cruise, water taxi
- Yacht clubs operating service launches and tenders
If you operate any kind of vessel commercially, or if you employ crew, or if you carry passengers for hire, you most likely need P&I that is specifically rated for what you do. A general liability policy with a marine endorsement is almost never the same product.
What Does P&I Insurance Cover?
A typical P&I policy covers:
Crew Liability and Injury
- Jones Act claims — the federal statute that gives seamen the right to sue their employer for negligence-caused injuries; broader than state workers' compensation
- Longshore and Harbor Workers' Compensation (USL&H) — federal workers' comp for maritime workers not covered by the Jones Act
- Maintenance and cure — the ancient maritime obligation to provide medical care and basic living expenses to injured seamen until maximum medical recovery
- Death on the High Seas Act exposures — wrongful death actions for fatal incidents in international waters
- Unseaworthiness claims — strict liability for crew injuries caused by unseaworthy conditions
Passenger and Third-Party Liability
- Passenger bodily injury and death
- Third-party property damage caused by the vessel
- Third-party bodily injury caused by the vessel or its operations
Pollution and Environmental
- Fuel and oil spill cleanup costs (under federal CERCLA, state pollution statutes, and international conventions)
- Pollution liability to third parties for environmental damage
- Government fines and penalties related to spills
Vessel-Specific Liabilities
- Wreck removal — federal and state authorities regularly require sunken or grounded vessels to be removed at the owner's expense, and the cost can exceed the value of the vessel
- Towage liability — both as the towing vessel and as the towed vessel
- Cargo liability — damage to cargo carried on the vessel
- Salvage costs — when another vessel saves yours from peril
- Collision liability beyond hull coverage limits
Operational Liabilities
- Quarantine expenses — when a vessel is held in port for health-related reasons
- Repatriation of crew — returning crew to their home country after a stranding or operational change
- Diversion costs — fuel, port fees, and time costs of unscheduled diversions for medical or operational emergencies
- Stowaway expenses — costs of dealing with unauthorized passengers
- Crew substitute expenses — covering the cost of replacing an injured or quarantined crew member
How Is P&I Different From General Liability or Commercial Auto?
The simplest way to understand the difference: a general liability policy is built for slip-and-fall claims at a brick-and-mortar business. A commercial auto policy is built for collisions on roads. Neither was written with maritime law in mind, and neither will respond to a Jones Act claim, a fuel spill cleanup invoice, or a wreck removal order from the Coast Guard.
If a passenger slips on the deck of your charter boat and sues, that is a P&I claim. If a deckhand falls into the bilge while working and is permanently injured, that is a P&I claim under the Jones Act. If your boat sinks in the channel and the Coast Guard orders removal at your expense, that is a P&I claim. None of these are general liability or commercial auto claims. They are not partial overlaps. They are categorical distinctions.
This is also why marinas, charter base operators, and lenders ask for "P&I" specifically rather than just "liability" — they want proof that the marine-specific exposures are actually covered by a policy that actually responds.
How Much Does P&I Insurance Cost?
P&I pricing varies enormously based on operation type, vessel size, crew count, navigation territory, passenger capacity, and loss history. A few representative ranges:
- Yacht-form P&I (bundled into a recreational yacht policy) — usually included as part of the overall yacht premium and not separately broken out; effective cost is typically a small fraction of the total yacht premium
- Charter boat P&I — annual premiums commonly run from $3,000 to $25,000 depending on passenger capacity, navigation, and crew
- Commercial fishing P&I — varies widely; often $5,000 to $50,000+ per vessel depending on size, crew count, and fishery
- Tug and towing P&I — $10,000 to $100,000+ per vessel depending on operation type
- Passenger vessel P&I — heavily driven by passenger capacity and route; can run from $5,000 for a small water taxi to hundreds of thousands for a large excursion vessel
The most reliable number is the one a specialty marine broker quotes against your specific operation. Generic estimators do not exist for P&I, and any quote that comes back without operation-specific detail is not a real quote.
Common P&I Insurance Claims
The kinds of claims P&I responds to in practice:
- A deckhand on a fishing vessel suffers a back injury during gear handling and files a Jones Act claim alleging unseaworthiness
- A passenger on a charter boat slips on a wet deck and breaks a hip, leading to a six-figure medical and pain-and-suffering claim
- A workboat sinks in a harbor; the Coast Guard orders wreck removal and the operator faces a $400,000 removal invoice
- A fuel transfer line ruptures during refueling; cleanup, government fines, and third-party claims compound to several hundred thousand dollars
- A tugboat is found partially at fault for damage caused to a tow during a routine harbor move
- A crew member is injured in international waters and the operator must pay maintenance and cure for an extended recovery period plus repatriation home
- A passenger ferry collides with a private vessel; both bodily injury and property damage claims fall to P&I beyond the hull policy limit
In each of these scenarios, a non-marine liability policy would either decline coverage outright or respond at limits that cannot meaningfully address the maritime claim. P&I is built specifically for these situations.
What Drives P&I Pricing
The factors that move P&I premium most:
- Operation type — passenger boats, tugs, and commercial fishing boats price very differently
- Vessel size, type, and value
- Crew count and roles — Jones Act exposure scales with crew
- Passenger capacity and revenue — more passengers means more exposure
- Navigation territory — coastal vs. offshore vs. international
- Loss history over the prior 3–5 years
- Vessel maintenance and survey condition
- Required limits and any contract-driven minimums (charter contracts, port agreements, lender requirements)
