Abstract

See full text

A method of establishing a fishing line comprises the steps of attaching attachment openings of a breakable link to a surface buoy and underwater gear, and disconnecting the surface buoy from the underwater gear by irrecoverably breaking the wall of one of the attachment openings at a weakened portion thereof, without breaking a join portion connecting the attachment openings. The weakened portion extends circumferentially from 150.degree. to 210.degree., i.e. for about a half of an entire circumference of the associated attachment opening. The thickness and/or material failure load of the weakened portion is from 50 to 70% of the thickness and/or material failure load of the remaining elements of the breakable link. The connecting portions may be rigidly integrated with each other, or pivotably attached via the join portion.
