B.6. Inspection
Access
Two ½-inch inspection plugs are located inside the cabin near frames 7½ and
13½. A borescope is required for internal inspection.
B.7. Diagonal
Stiffeners
The ¼- by 3-inch diagonal stiffeners (Figure 3-17), spaced 12 inches apart,
are designed to efficiently disperse impact energy. This unique herringbone
framing directs impact energy along its natural course of flow.
B.8. Rig Tubes
Rig tubes are located directly below the main deck on the port and starboard
sides and terminate at watertight bulkhead 13½, where they interconnect with
the transverse rig tube. There are multiple access points to the rig tubes.
B.9. Hull
Access Plug
The hull access plug is located forward of the transducer in the step. This
can be used for hull draining and borescope access.
