What Are the Institute Yacht Clauses?

Agreed Value is popular for classic or high-value yachts, while ACV suits newer boats.

Deductibles / Excess

Your deductible is the amount you pay before insurance kicks in. The IYC allows fixed deductibles (e.g., $5,000) or percentage-based ones (e.g., 5% of the insured value). For a $400,000 yacht with a 5% deductible, you’d pay $20,000 upfront for any claim.

How Navigation Limits Affect Your Coverage

The IYC restricts coverage to specific geographic areas, called navigation limits. If damage occurs outside these limits, your insurer may deny the claim.

Scenario: Damage Outside Navigation Limits

Your boat: $600,000 yacht insured under IYC with navigation limits set to the U.S. East Coast.

Incident: You sail to the Caribbean during hurricane season. A storm damages your hull.

Outcome: The insurer denies the claim because the incident occurred outside your policy’s navigation limits. You pay 100% of the $150,000 repair cost.

Lay-Up Periods and Warranties

If you store your yacht for an extended period, the IYC requires a "lay-up warranty" to keep coverage active. This includes securing the boat, draining fuel tanks, and storing it in a protected location.

Scenario: Breaching Lay-Up Warranty

Your boat: $300,000 yacht stored on a Florida marina with a lay-up warranty requiring winterization.

Mistake: You skip draining the fuel tank, and a fuel line leak causes a fire during storage.

Outcome: The insurer denies the claim due to the lay-up warranty breach. You pay the full $100,000 repair cost.

Named-Storm Deductibles and Salvage Costs

The IYC often includes a "named-storm deductible" for hurricanes and tropical storms. This is a separate deductible (e.g., 5%) that applies only to storm-related damage.

Scenario: Named-Storm Deductible in Action

Your boat: $500,000 yacht with a 5% named-storm deductible and a $10,000 fixed deductible.

Incident: Hurricane "Zoe" damages your deck, costing $80,000 to repair.

Calculation: 5% of $500,000 = $25,000 named-storm deductible. Total out-of-pocket: $25,000 (no fixed deductible applies for named storms).

Salvage, Wreck Removal, and General Average

The IYC covers costs to recover a wrecked boat (salvage) and remove debris (wreck removal). It also includes "general average," a legal principle where all parties share costs if cargo is jettisoned to save the yacht.

Example: General Average in Action

Incident: To save your yacht from capsizing in a storm, you throw overboard $20,000 worth of cargo.

Coverage: The IYC pays for the lost cargo and shares the cost with other parties (e.g., the cargo owner) under general average rules.

Seaworthiness and Total Loss

The IYC assumes your yacht is seaworthy (fit to sail safely). If an insurer deems it unseaworthy before a loss, they may deny the claim. A "total loss" occurs when repair costs exceed the boat’s value, while a "constructive total loss" happens when repairs are too expensive to justify.

Crew Liability and Pollution Coverage

The IYC extends to crew-related risks. If a crew member is injured, the policy covers medical costs and legal fees. Pollution liability covers oil spills or environmental damage, a critical coverage for yachts with fuel systems.

Scenario: Crew Injury Claim

Your boat: Charter yacht with 4 crew members.

Incident: A crew member falls overboard and fractures their leg.

Coverage: The IYC pays $50,000 in medical bills and $10,000 in legal fees for a slip-and-fall lawsuit.

Putting It All Together: Your Action Plan

Review your IYC policy annually to ensure navigation limits, lay-up warranties, and deductibles align with your boating habits. For example, if you plan a transatlantic voyage, confirm your limits include international waters. Also, choose agreed value over ACV if your yacht is classic or holds its value. Finally, never skip the lay-up warranty during storage—it’s a small step that could save you thousands.
