There ya go ... Hal hit it RIGHT on the head of the nail
One more thing to note ... we ALSO have to our adjustments a bit more precise as well .
For those that know nothing about real , full sized boats , then go in the opposite direction ...
Say , you are running the same 36 inch boat , now make that a 18 inch boat and try running it at the same speeds ... ( gonna need a LOT more fine tuning that what you had to do on the 36 incher )
