Regulation 7 - Operating conditions

  (1) The number and type of operating conditions to be considered shall be to the satisfaction of the Administration and shall include the following, as appropriate:

  • (a) departure for the fishing grounds with full fuel, stores, ice, fishing gear, etc.;

  • (b) departure from the fishing grounds with full catch;

  • (c) arrival at home port with full catch and 10% stores, fuel, etc.; and

  • (d) arrival at home port with 10% stores, fuel, etc. and a minimum catch, which shall normally be 20% of full catch but may be up to 40% provided the Administration is satisfied that operating patterns justify such a value.

  (2) In addition to the specific operating conditions given in paragraph (1) the Administration shall also be satisfied that the minimum stability criteria given in regulation 2 are met under all other actual operating conditions including those which produce the lowest values of the stability parameters contained in these criteria. The Administration shall also be satisfied that those special conditions associated with a change in the vessel's mode or areas of operation which affect the stability considerations of this chapter are taken into account.

  (3) Concerning the conditions referred to in paragraph (1), the calculations shall include the following:

  • (a) allowance for the weight of the wet fishing nets and tackle, etc. on the deck;

  • (b) allowance for ice accretion, if anticipated, in accordance with the provisions of regulation 8;

  • (c) homogeneous distribution of the catch, unless this is inconsistent with practice;

  • (d) catch on deck, if anticipated, in operating conditions referred to in paragraph (1)(b) and (c) and paragraph (2);

  • (e) water ballast if carried either in tanks which are especially provided for this purpose or in other tanks also equipped for carrying water ballast; and

  • (f) allowance for the free surface effect of liquids and, if applicable, catch carried.
