ANNEX XIU.K.AUTHORISED TOPSIDE CHAFERS
1.ICNAF-type topside chaferU.K.
The ICNAF-type topside chafer is a rectangular piece of netting to be attached to the upper side of the codend of the trawl net to reduce and prevent damage so long as such netting conforms to the following conditions:
this netting shall have a mesh size not less than that specified for the codend in Article 10;
this netting may be fastened to the codend only along the forward and lateral edges of the netting and at no other place in it, and shall be fastened in such a manner that it extends forward of the splitting strap no more than four meshes and ends not less than four meshes in front of the cod line mesh; where a splitting strap is not used, the netting shall not extend to more than one-third of the codend measured from not less than four meshes in front of the cod line mesh;
the width of this netting shall be at least one and a half times the width of the area of the codend which is covered, such widths to be measured at right angles to the long axis of the codend.
2.Multiple flap-type topside chaferU.K.
The multiple flap-type topside chafer is defined as pieces of netting having in all their parts meshes the size of which, whether the pieces of netting are wet or dry, is not less than that of the codend, provided that:
each piece of netting:
is fastened by its forward edge only across the codened at right angles to its long axis;
is of a width of at least the width of the codend (such width being measured at right angles to the long axis of the codend at the point of attachment); and
is not more than 10 meshes long; and
the aggregate length of all the pieces of netting so attached does not exceed two-thirds of the length of the codend.
POLISH CHAFERU.K.
3.Large-mesh (modified Polish-type) topside chaferU.K.
The large-mesh topside chafer consists of a rectangular piece of netting made of the same twine material as the codend, or of a single, thick, knotless twine material, attached to the rear portion of the upper side of the codend and extending over all or any part of the upper side of the codend and having in all its parts a mesh size twice that of the codend when measured wet and fastened to the codend along the forward, lateral and rear edges only of the netting in such a way that each mesh of the netting coincides with four meshes of the codend.
