I think one way of finding out which are the most poular ribs in te UK is to call manufacturers and ask them what there production capacity is and how long the delivery time. If you do that I think you'll find in the leisure market that Ribcraft and Scorpion are up there.
Commercial Avon, Halmatic, Delta and Ocean dynamics
Imported boats I think the Gemini's take some beating but I've sen a nice boat from france called a Magnum
If you want a boat that's ffff fast then Phantome Evo's and if you can afford it a MarkPascoe Limited has got to be the ultimate machine.
there are aot of other good boats out there but I think these names are about the most popular
All in all however I think the most desired RIB is a Scorpion
