50ft oh casts, comparison increased casting arc

Purpose

The purpose of this comparison is to show the impact of increasing the casting arc.

The comparison is made between two simulations:

· The 50ft oh ref. cast.

· “50ft arc +20 deg” simulated with the casting arc increased by 20 deg.

Input, casting stroke

The casting arc, shown below, is the only input that differs between the two compared cases.

Input, equipment

The equipment for both simulations is identical, see the 50ft oh ref. cast.

Output, animation

Comment, animation:

The cast with increased casting arc produces a more curved rod tip path. This, in turn, produces a wider loop (increased loop apex radius) with increased normal drag and, consequently, a less efficient cast.

Output, graphs

The graphs considered most relevant for the comparison are presented below. For explanations to the graphs please see the 50ft oh ref. cast.
