AMIM · Understand the traps and how to avoid them.
Treating 'marine insurance' and 'ocean marine' as interchangeable labels and applying ocean hull/cargo rules to an inland marine exposure (or vice versa) when classifying a scenario.
The two terms overlap in everyday usage, so candidates default to the more familiar ocean-marine framework without checking the exposure's actual transit/storage character.
What to do instead
Before answering, write one line identifying the exposure (vessel, cargo in transit, bailee property, fixed commercial property) and then select the coverage family that governs it; only then read the answer choices.
Confusing 'perils of the seas' with general 'fortuitous loss' and accepting ordinary wear, inherent vice, or crew negligence as a sea peril.
The phrase sounds broad, and candidates import general property 'fortuitous' reasoning into a named-perils marine clause.
What to do instead
Memorize that perils of the seas means fortuitous accidents of navigation, not ordinary action of wind and waves, and test each scenario against whether the loss was accidental and external to the subject matter.
Applying commercial property 'occurrence' and 'cause of loss' forms to inland marine floaters without adjusting for the follow-the-subject-matter and transit features.
Most candidates have stronger commercial-property training and unconsciously use the CGL/property cause-of-loss framework.
What to do instead
For each inland marine question, explicitly identify the covered property, the territory/transit scope, and the valuation basis before evaluating exclusions.
Misapplying the bailee's interest and the customer's interest in a bailee exposure, treating the bailee as owning the goods.
Bailee coverage insures the insured's legal liability or the property of others in its care; candidates collapse the two interests.
What to do instead
State whose property it is and what legal interest the insured holds, then match to bailee customers' goods coverage versus the customer's own policy.
Confusing protection and indemnity (P&I) liability with hull and machinery coverage when a crew injury or third-party property damage is described.
Both are 'marine' and both involve the vessel, so candidates pick the vessel-related coverage without checking the insured interest.
What to do instead
Ask 'whose loss is this?' - damage to the insured's own vessel is hull; liability to others (crew, third parties, pollution) is P&I.
Treating collision liability under a hull policy as equivalent to full P&I third-party liability.
The collision clause is embedded in hull forms, so candidates assume it covers all third-party consequences.
What to do instead
Distinguish the hull collision clause (damage to the other vessel, with the running-down/nautical fault limits) from P&I's broader third-party liability, and check which is being asked.
Assuming cargo coverage attaches at the seller's door and ends at the buyer's door without checking the warehouse-to-warehouse and transit termination provisions.
Candidates rely on the shorthand 'warehouse to warehouse' without knowing the attachment and termination conditions.
What to do instead
For every cargo question, name the attachment point, the termination trigger, and the duration of cover, and verify against the transit clause described.
Ignoring Incoterms and the transfer of risk when deciding who bears the loss in a cargo scenario.
Candidates focus on the insurance policy and skip the sale contract's risk allocation, which determines insurable interest.
What to do instead
Identify the Incoterm and the point risk passes, then determine who has insurable interest at the time of loss before selecting coverage.
Skipping the average/particular average/general average distinction and treating every partial loss as fully recoverable.
The terminology is archaic, so candidates gloss over it and apply ordinary property partial-loss logic.
What to do instead
Write the definitions in one line each (particular average = partial loss borne by the affected interest; general average = voluntary sacrifice apportioned across all interests) and classify the loss before answering.
Answering underwriting and management questions from general commercial instinct rather than marine-specific rating factors such as voyage, vessel class, cargo type, and trade route.
Management/underwriting items feel like general business judgment, so candidates skip the marine risk factors.
What to do instead
Before choosing, list the marine rating factors present in the stem (vessel age/class, cargo, route, season, packing) and pick the answer that reflects those factors explicitly.
