I need some help with engine center line relative to the hulls. I have a 24' catamaran project boat that has never been in the water. I want some input on where I should set the prop center line in relation to the inside vertical chine of the tunnel. There seems to be a few different ideas out there... Do I set it in the middle of the sponson or towards the inboard side but not directly in the flow off the inside of the tunnel? Thanks for the help.
