EVERGREEN Corsair 50 #59 Skeleton Chart

The reason it catches fish is the fat tail.
The sinking pencil Corsair 50 combines outstanding flight distance and high action response with its unique fat tail shape.
It is particularly effective when searching over a wide area or approaching distant pin spots.
The "fishable action" creates natural vibrations by swinging the tail tightly and responsively, and can induce bites not only in highly active situations, but also in selective situations where lures with strong vibrations are avoided.

Fat tail design
A unique fat tail design that is fat when viewed from above and slim when viewed from the side.

The tail is designed to be fat and has firm buoyancy, making it possible to place the weight on the rear of the body without sacrificing action response.
As a result, it achieves both outstanding flight distance and high action response with a stable flying posture.

The slim design of the sides makes the vibrations generated during action natural.

Low center of gravity molded weight
Low center of gravity molded weight fixed at the optimal position at the bottom of the body.
The lower center of gravity improves action response, and the air chamber inside the body becomes larger, increasing buoyancy.
