     (2) There is a general average act where any extraordinary sacrifice or expenditure is voluntarily and reasonably made or incurred in time of peril for the purpose of preserving the property imperilled in the common adventure.
     (3) Where there is a general average loss, the party on whom it falls is entitled, subject to the conditions imposed by maritime law, to a rateable contribution from the other parties interested, and such contribution is called a general average contribution.
     (4) Subject to any express provision in the policy, where the assured has incurred a general average or expenditure, he may recover from the insurer in respect of the proportion of the loss which falls upon him; and in the case of a general average sacrifice, he may recover from the insurer in respect of the whole loss without having enforced his right of contribution from the other parties liable to contribute.
     (5) Subject to any express provision in the policy, where the assured has paid, or is liable to pay, a general average contribution in respect of the interest insured, he may recover therefor from the insurer.
