What does boulter mean?
A boulter is a long fishing line fitted with many baited hooks at intervals, designed to be laid across a river, lake, or tidal channel and left to catch fish passively over hours or overnight. The technique targets species such as pike, eels, and other coarse fish that take stationary baits, and the device is closely related to the North American trotline and the British spiller. The term is chiefly British and belongs to the specialised vocabulary of traditional angling rather than everyday speech, appearing most often in fishing manuals, historical accounts of commercial freshwater fishing, and regional dialect writing. For readers outside angling circles, the boulter is interesting chiefly as a window into older, low-technology methods of harvesting fish: a single length of cord, weighted and anchored, could do the work of dozens of rods. The word survives today mainly among traditional fishermen and historians of the craft.
nounA boulter is a long fishing line bearing multiple baited hooks, typically set across a river or along the seabed to catch fish such as pike or eels; it is also known as a trotline or spiller.
- A long fishing line carrying numerous baited hooks, used especially for catching coarse fish such as pike and eels.
"The eel fisherman laid his boulter across the estuary at dusk and returned at dawn to haul in the night's catch."
"He baited every hook on the boulter before lowering it into the slow bend of the river."
"Traditional eel fishermen on the fens still speak of the boulter as the workhorse of their trade."
Standard plural; used when speaking of several such lines or the fishermen's collective gear.
"The crew tended half a dozen boulters spread across the estuary."
Before rod-and-reel sportfishing took over, commercial anglers stretched single lines studded with dozens of hooks across whole rivers — and called them boulters.

Etymology of boulter
Boulter derives from the English verb 'to bolt', here meaning to fasten or secure, referring to the way the long line is anchored or secured across a stretch of water. It developed within British angling vocabulary, where it sits alongside related terms such as 'spiller' and 'trotline' describing similar multi-hook tackle. Its exact date of first attestation is uncertain, but it appears in English sources by at least the nineteenth century.
How boulter is actually used
The word is chiefly British and largely confined to angling contexts; in North American usage the equivalent gear is more often called a trotline or setline. It is a technical term rather than part of everyday vocabulary, so it appears mainly in fishing literature and regional dialect writing.
