CBTF - the technology of the future


 
The Daily Sail spoke to America's Cup veteran Peter Isler about his time on the Red Hornet
This article follows on from our feature yesterday on the Australian big boat Wild Oats . The participation of Wild Oats in the Admiral's Cup is the first occasion a boat with CBTF (canting ballast-twin foil) technology has been raced in anger in Europe. This will have made some impression on the racing establishment and this can only increase once the new generation maxZ86 maxis for Roy Disney and Hasso Plattner hit the water later this year, for they too will have fore and aft rudders and a canting keel - the biggest boats to date to have this system. There is also a distinct possibility that the system will be allowed under the new Volvo Ocean 70 rule... Both the new maxZ86s are Reichel-Pugh designs and the result of CBTF Co (originally known as DynaYacht, the company that developed and patented the system) to open their product out to other designers. Despite it only starting to take off with the success of Wild Oats and the maxZ86s, CTBF has been in development for some 15 years now. The system was originally developed by Alberto Calderon, who had been involved with Tom Blackaller's tandem keel 12m used in the 1987 Cup. Driving force behind the technology is now Chuck Robinson whose company CBTF Co now develops and promotes CBTF technology. The first attempts with the system were carried out retrofitting the appendages to a Soling, then a stretched Hobie 33 and standard production Catalina 30. These were followed by Red Hornet. the first purpose-built CBTF boat. She was the test bed for the first production CBTF boat, Schock 40, of which around 10 examples now exist. This boat won Sailing World/Cruising World magazine's Best Innovation, Best Sportsboat and Best of the Year awards in 2001. America's Cup veteran and commentor Peter Isler
