Jet

I'm guessing Tony Cerff has shaped more twin fins than anyone else on the planet. According to my records he did time on the planner through the 80's at Mad Dog, JET, Local Motion and Town & Country (Australia). At Mad Dog he shaped many, many MR brand twinnys. This lovely little 6'0", channel bottom, single fly swallow tail JET by Tony came out of the same factory at Byron Bay.
I like its narrow tail and high wide point but its boxy rails and and little if any rocker make it tricky to ride.
