It is a 12-foot Walker Bay Genesis RIB with a "rather bashed up looking" 25HP Mercury outboard (I believe that their nice 8HP outboard went missing not too long ago). It also has the markings of T/T Nauticat of Fowey.
Nauticat of Fowey is one of our favorite charter catamarans and we hope that Ali & Bill recover their dinghy.
You can see their charter brochure here: click for Nauticat's brochure.
Dinghy theft is akin to horse thiefing, in my opinion, if not worse!
