I know of V8 supercar drivers Jason Bargwanna, Greg Murphy and Nathan Pretty have all had a go at Jet sprint boat racing and have done reasonably well..it seems as you say a racer can race anything and be fairly competitive....jet sprint boats are awesome and not so long ago one of my pit crew guys had a stint in one as a navigator and really enjoyed it and came back saying boat drivers are just as good as car drivers without a doubt.
heres a pic of my pit crew guy Adam at full flight.
