The boat on the Boscombe footage is indeed a RIB, it enters the Wokka at a fair rate, about 5kt. Better carried inside than underslung , as a surprised motorist found when one was dumped (Oscillating badly) from a Wokka near the A303 some years ago.
Then there was Smokey's (IIRC?) attempt to undersling the Ark Royal on Ex Purple Helmet in 1987...
