Hello crispyspa
One of my first boat hulls twisted a little in the construction period.This led me to having to adjust the air rudders about 10 degrees to the left to correct the drift.
You mentioned that your first stage of hull construction did not go directly to plan.
May be you need to try a water rudder . Or just angle the engine in the opposite direction as to counter act the prop walk.
My theory is there is no such thing as a problem ! Just fix IT . And show us some Vids.Please! . That thing looks like it could kick AAAAARRRRRSSSSS
