What is the maximum shell diameter for manual firing on a floating vessel?

• A. 4 inches
• B. 8 inches
• C. 12 inches
• D. 6 inches

Answer: (D)

On a floating vessel, manual firing must be kept within safer, more controllable limits because the platform is moving and people are nearby. The maximum shell diameter allowed for hand firing is six inches, which helps keep recoil, blast effects, and debris within manageable levels for deck personnel. Shells larger than six inches require mechanical or remote firing and more stringent safety measures, so they aren’t permitted for hand firing on a floating vessel. So, six inches is the correct maximum for manual firing on a floating vessel. Smaller sizes like four inches are allowed but do not represent the upper limit, while larger sizes would exceed the safety requirements for hand firing.
