• and
• a replaceable bullet penetrable target mounted in a substantially vertical plane between said spaced apart poles of said support means substantially above the water level, said target being spaced a substantial vertical distance above said submerged hull and water level;
• said hull including vertical and horizontal stabilizing blades extending therefrom to maintain said hull at a predetermined depth below the water level when it travels regardless of whether the target is penetrated.
