Fishing Vessel Safety Regulations

Version of section 43 from 2006-03-22 to 2017-07-12:

  •  (1) Subject to this section, every fishing vessel shall carry a total anchor weight of not less than that derived from the following formulae:

    • (a) for cubic number up to 566

      W = 0.64 CN, and

    • (b) for cubic number over 566

      W = 0.48 CN + 91


    • (c) W = total anchor weight in kilograms,

    • (d) CN = cubic number (L x B x D),

    • (e) L = length of vessel in metres,

    • (f) B = greatest breadth of vessel in metres, measured to the inside of planking or plating, and

    • (g) D = the depth of the vessel in metres, measured at amidships from the top of keel to the top of the deck beam at side except that, in the case of a vessel that has a raised deck aft that extends forward of amidships, the depth D shall be measured to the line of that deck and, in the case of an open construction vessel, the depth D shall be measured to the top of the gunwale.

  • (2) Where approved patent anchors are adopted, 40 per cent of the total anchor weight shall be deducted, but the length and size of the anchor cable shall be based on the normal anchor weight.

  • (3) Where “W” is not more than 135 kg or 80 kg in the case of patent anchors, one or two anchors may be carried.

  • (4) Where “W” is more than 135 kg or 80 kg in the case of patent anchors, two anchors shall be carried.

  • (5) Where two anchors are carried, the weight of the main anchor shall be not less than 60 per cent of “W” and that of the second anchor shall be not less than 40 per cent of “W”.

  • (6) Trawl boards or scallop nets used in normal fishing operations may be used on a fishing vessel in lieu of anchors if they do not weigh less than the required total weight and in such case the trawl board or scallop net cable used may be accepted in lieu of the anchor cable required by subsection (8).

  • (7) A windlass or winch shall be provided on a fishing vessel that carries an anchor weighing more than 70 kg or if a winch normally used for fishing operations can be used, it may be accepted in lieu of an anchor windlass.

  • (8) Subject to subsection (6), an anchor cable of link chain, wire rope, manilla rope or other rope of a material of equal or greater strength than manilla hemp shall be carried in accordance with the following table:

    Weight of main anchor in kilograms i.e. at least 60 per cent of “W”Minimum diameter of link chain or wire rope in millimetresMinimum circumference of manilla or other rope in millimetresTotal length of cable in metres
