Filing the rudder

Here's some reading in the link below

By the way, it would be nice to update your vibration/flywheel issue from last year   Here's a link to make it easy to update

Good update to the other thread

Maybe the reading in the link told you something in one thread or another about rudder tuning.

If not...........ask away

Turning hard to the right and a lot easier to the left comes with having a RH rotation prop and you'll probably never tune that out with rudder filing.

It's mostly for affecting the effort required to keep the boat going in a straight line

I’ve never heard of filing to make it neutral, but I understand why you’d want to. For river cruising, that constant fight is annoying. There is an argument that it increases safety, but I don’t know how much I agree. That said, It is very common to add load, for skiing the slalom course. Constant load means very slight movements are all that is necessary, as any movement effects boat path. Neutral gives you free-play, and makes it harder to keep a straight path.
That’s why the tunable rudder started in 99. It made the Ski Nautique easier to handle, not that the TSC hull was at all hard to drive. I’m going to get my 4th TSC hulled 196 tomorrow, so it’s my favorite of all time.
A lot more of skiers with the pre 99 196’s have ground the rudder to get that loaded feeling.
