I'm sure this is the one. The one I mentioned is the blue one (team in yellow.)

The collars are made from closed cell foam (similar to Ethafoam or jiffycell) i think and have a pvc or polyurethane cover over them.

SAFE Boats make foam collared boats in the US. They supply the Defender 25 foot Fast Reponse boats to the USCG, among others.

That looks about right Steve, but this one was more tube shaped except for the squared nose Like that one has. It's a good looking RBB (cheers polwart!) and I've seen the students hammering it on the river. Seems to shift well too.

The RNLI's E class lifeboat on the Thames is an RBB:

We've built numerous "Buoyant Fendered Topside" boats and having the facility to build them in house allows us to manufacture the shape to suit. The FRCs and MoR SOLAS vessels have a larger section as buoyancy, slamming and dropping are key to the craft's survivability in the harshest of environments; we have however produced craft with the same principle but with a half rounded cross-section rather than rectangular to give the aesthetic effect of a traditional RHIB

The benefit of this type of collar is not only its impact resistance and durability but also the fact that it bonds/fastens to the outboard side of a raised hull side; thus effectively increasing the useable deck width, bearing in mind an inflatable collar would sit half in/half out of the boat taking up valuable deck space.

How do they compare for buoyancy and life expectancy (of the "tubes") compared with RIB's Rich?
