Well..correct but Velden was one of the first developing safety cells. I drove a Velden 1985 with safety cell. Renato built a few boats with safety cells but not a very good one.
Second Efforts V8 boats did use canopies..This picture is from 1988.
I drove a new F3/OE class Burgess 1990 with canopy..I did like it..but not very much..:)
