I never realised that some aircraft designer was perverse enough to provide throttles working in the inverse sense!! Back in 1978, when I bought a Freeman 22 cabin cruiser, I found that the throttle on that was also operating backwards...it was the first modification I made, as I knew that closing the throttle on approaching a lock would have lead to a re-enactment of the St.Nazaire raid! Forward to go faster..was ever the way.
