Rule XIII Deductions from Cost of Repairs

Repairs to be allowed in general average shall not be subject to deductions in respect of ‘new for old’ where old material or parts are replaced by new unless the ship is over fifteen years old in which case there shall be a deduction of one third. The deductions shall be regulated by the age of the ship from the 31st December of the year of completion of construction to the date of the general average act, except for insulation, life and similar boats, communications and navigational apparatus and equipment, machinery and boilers for which the deductions shall be regulated by the age of the particular parts to which they apply.

The deductions shall be made only from the cost of the new material or parts when finished and ready to be installed in the ship. No deduction shall be made in respect of provisions, stores, anchors and chain cables. Drydock and slipway dues and costs of shifting the ship shall be allowed in full.

The costs of cleaning, painting or coating of bottom shall not be allowed in general average unless the bottom has been painted or coated within the 24 months preceding the date of the general average act in which case one half of such costs shall be allowed.
