Steele Marine would only build a flatbottom circle boat - nothing for play. No matter because they went out of business in January 2001 and obviously no longer own the mold.
I have an old race program from the Rusty Biesemeyer Regatta and Western Divisional circle race at Firebird in 1991. I try to dig it up - there was some interesting stuff on Biesemeyer in it. If I find it, I'll post it here.
