Claims

[Scope of utility model registration request]

In a stern valve attached to a two-shaft, two-rudder stern boat in which the upper rear end of the hull extends rearward, a semi-spindle-shaped body or a spindle-shaped body extends rearwardly and horizontally to the lower rear end of the hull. A stern valve that is characterized by being protruded with a relatively large gap between it and the upper part.
