Where a ship is damaged, but is not totally lost, the measure of indemnity subject to any express provision in the policy, is as follows--
(1) where the ship has been repaired, the assured is entitled to the reasonable cost of the repairs, less the customary deductions, but not exceeding the sum insured in respect of any one casualty;
(2) where the ship has been only partially repaired, the assured is entitled to the reasonable cost of such repairs, computed as above, and also to be indemnified for the reasonable depreciation, if any, arising from the unrepaired damage, provided that the aggregate amount shall not exceed the cost of repairing the whole damage, computed as above;
(3) where the ship has not been repaired, and has not been sold in her damaged state during the risk, the assured is entitled to be indemnified for the reasonable depreciation arising from the unrepaired damage, but not exceeding the reasonable cost of repairing such damage, computed as above;
(4) where the ship has not been repaired, and has been sold in her damaged state during the risk, the assured is entitled to be indemnified for the reasonable cost of repairing the damage, computed as above, but not exceeding the depreciation in value as ascertained by the sale.
