Which boat is specifically used for VBSS operations at sea?

The 11M RIB (Rigid Inflatable Boat) is specifically designed for Visit, Board, Search, and Seizure (VBSS) operations at sea due to its optimal combination of speed, maneuverability, and handling in various sea conditions. Its larger size compared to the 7M RIB allows for a more substantial crew capacity, which is essential during operations that may require additional personnel or equipment. The 11M RIB can also carry tactical gear and boarding teams efficiently, enhancing the operational capabilities during VBSS missions.

In contrast, other options such as the 7M RIB and the captain's gig may not provide the same level of operational capacity and versatility needed for such specialized tasks. While the captain's gig is typically used for transport to and from larger vessels, it is not primarily designed for the rigorous demands of VBSS operations. The admiral's barge, although suitable for formal transport, is not equipped for the tactical requirements of boarding operations either. Thus, the 11M RIB stands out as the optimal choice for VBSS operations due to its specific design features and operational advantages.
