Summary

John McLean Hazard's Administrator v. New England Marine Insurance Company…

If worms infest the Pacific ocean, so that a vessel upon entering it, and not properly protected, is necessarily exposed to destruction, the danger is not an extraordinary peril, against which alone insurance is made; but a certain one, against which the insured is bound to provide.
A contrary doctrine would involve the absurdity of converting the contract of insurance into one of indemnity against certain loss.

If, for instance, a partial damage should not amount to the stipulated average of five per cent on the value of the vessel, which is necessary to create liability on the part of the insurer; how easily might it be made one, if left unrepaired until sufficiently increased or connected with others. And if a partial loss, one-third of the expense of repairing, which must fall upon the insured, should be worse for him than a constructive total loss, as very frequently happens, what would be more easy than to suffer it to become one?
