I think Jon Aldiss had his wave piercing jet turbine rib at last years RIBEX. (04). I seem to recall a long black carbon fibre thingy on land and wondering just how it would perform at sea!
The RB4 rib had a fuel tank failure somewhere off the Northumberland coast on RB4. I think their underdeck tank had failed so their fuel was slopping around in the bilges. Certainly they ended up putting out a distress call and I think getting some fuel from a passing rig supply boat! We were about 20nm away from them in Cyanide at the time and I recall having a conversation with the coastguard about offering assistance.
I also think I recall that they went back and redid round britain in the boat after their attempt came to a halt on the East Coast. Nice guys but feckin nutters!
