Bimini Twist – A type of knot or hitch used to produce a double line segment to attach a leader. As a hitch it is not strictly a knot but it produces a connection which is extremely strong with little drop in the line’s breaking strain. Needs practice to tie successfully.

Birler blade - a small metal or plastic spinner blade used on a clevis ahead of a baited hook as an attractor. Also known as a dirler blade.
Black lug – The larger or the two main lugworm species. Lives in vertical burrows and is often fished gutted and after freezing. See also lugworm.
Blank - The basic fibreglass or graphite shaft or rod without any guides or hardware attached after is leaves the manufacturing process. Also refers to a fishing session where no fish are caught.
Blow lug – Also known as the common lugworm this species lives in a u-shaped burrow with a cast at one end and a blow hole at the other. Usually fished fresh and alive. See also lugworm.
Bluey – Bluey is the common name given to the Pacific saury a fish used for bait and normally supplied in a frozen state.
Boat draw - the draw for places on a boat, usually during a competition.
Boil - The term used to describe the frenzy of an attack on a school of baitfish by larger fish.
Bomb - An aerodynamically shaped lead weight.
Boom – A metal or plastic device to present a hook snood or trace. They can be fixed like the French boom or sliding on the line as with a zip slider or tubing boom.
Brackish water - Water with a salt content between 1000 and 4000 parts per million found where rivers meet the sea.
Braid or braided line - A type of line formed from woven, multi-filament, polyester, fibres which has a low diameter to breaking strain ratio and very low stretch properties. Widely used by boat anglers particularly in deep water and becoming more common among shore anglers.
Breakaway lead – A lead with swivelling grip wires. Originally only produced by the Breakaway Company it has now become a generic term for any lead of this type.
Breaker - A wave that has become so steep that the crest of the wave topples forward as it reaches shallow water.
Breaking strain – Sometimes shortened in print to BS. The amount of pressure that a line is supposed to be able to withstand before it breaks. 50lb breaking strain line is stronger than 20lb. Manufacturers tend to under estimate the breaking strain of their lines particularly with braid. A line marked as IGFA rated lines should be designed to break at or before their stated breaking strain.
Bristle booms - a fine plastic boom that has its ends blobbed on a hot surface and attached at one end to the trace body with a hook snood at the other. Also known as a matchstick boom.
Bulk shot - A number of split shot grouped together on the line when float fishing concentrating weight at a particular point.
Butt – The lower end of a rod which houses the reel seat and terminates in either a soft pad or a slotted attachment which fits into a butt pad gimbal.
Butt pad - A leather, plastic or rubber pad strapped around the waist or on the thighs into which the butt of a rod is placed so greater leverage can be exerted when fighting large fish. It may be fitted with a swivel gimbal.
