Abstract
This paper analyzes a fishing tackle consisting of bar float, line, sinker, hook line, subsinkers, and hook. Three arrangements of the subsinkers attached to the hook line are considered: 1) free design without subsinkers, 2) equal design with a pair of identical subsinkers, and 3) unequal design with a light sinker followed by a heavy one. Fluid-dynamic coefficients are identified to calculate, for instance, bar float drag and friction, and fishing tackle simulations are carried out using a multi-link model proposed by the authors. It turned out, among other things, that the free design can create a good float response to a weak fish bite.
