Artikel 69

Subject to the restrictions stated below, any space exclusively appropriated to and used for the keeping of boatswain's stores shall be deducted from the gross tonnage.
The expression “boatswain's stores” shall include all stores necessary for working and upkeep of the ship and which are in charge of the boatswain. In general, the boatswain's stores will contain wires, hawsers, cordage, tar, paint, blocks, shackles, awnings, tarpaulins, tackles, brooms, swabs, buckets, etc.
The deduction allowed for boatswain's stores shall be limited according to the following scale:
If in ships having a gross tonnage not exceeding 150 register tons, or 424.93 cubic metres, boatswain's stores are kept in a space not solely appropriated for such purpose, the deduction for boatswain's stores according to the above scale shall still be granted.
In fishing and hunting ships (e.g., whalers and sealers) having a gross tonnage exceeding 150 register tons, or 424.93 cubic metres, where there is no separate boatswain's store-room, a suitable deduction not exceeding 3 tons, or 8.50 cubic metres, shall be made for the boatswain's stores carried in the room for fishing and catching gear.
