There were E runabouts in the 1953 nationals at Oakland (not formula E, mod). Seems like it could be a fun class to try to bring back. Get a D runabout, modify decking a little and hang a 45ss OMC on the transom & race with two persons. Or experiment with deeper pleasure hulls like OPC of olden days.
Might be a better chance for more rigs in an exciting class like this than the fields seen in two-man, 850 or 1100? In the alternative how about two-man stock with a club foot motor of under 50ci?
I know- too many classes already and 45ss are getting rare but it is a nice fantasy. Could add additional spectator interest to an all stock race schedule.
