The
classic A frame provides the height necessary for a donkey
engine to hoist the catch up onto the culling board. The ropes,
called warps, are of lengths roughly forty to fifty feet. Each pulls
a dredge, which is like a rectangular basket, along the bottom.
A single trip along the bottom, lasting from roughly fifty to several hundred
yards, is called a tow. Most boats fish eight dredges at a time.
