The APBA F1 Kilo is held by a Stepp bottom boat. Is that anything like a step bottom boat? I agree that Stepp's are faster.
Sutphen F2 record was in 98 or 99, not that long ago. Doug Lewis was on the throttles and they carried the weight of a third person. I'd love to see them out there racing again. With the rough water schedule they'd kick a lot of a$$.
