Rudder travel question?

[Cooper]

Hey guys, what degree of travel do most boats have in their rudder? I assume a sport boat will have more than say a saw boat. For a fast hull would 30degrees be enough? 30 degree from centerline, so 60 degree of total travel. I know this can be limited by end point and subtrim but I am using a new rudder setup (new for me as I'm not familiar with it) and just wanted some input.

It is where you feel comfortable. There's really no rule other than make sure the rudder isnt at it's turning limit before the servo is.

I'm messing with a pull pull rudder set up with mock hydraulic arms. Seems like the rudder is limited to 30 degrees. That's fine with me as I'm never going to be max rudder while moving at speed. Just wanted to know. Seems like these style rudders have to be set up right or they will bind.

Id leave it with max movement, but remember that a hard turn is probably severe .. dial it back if it's a bit wild.

I have my gear set up with exponential on the steer.. first 1/2 the wheel is gentle, the rest adds 75%.

Answer: the minimum amount needed to make the tightest turn you will have. That means a lot of different "degrees" of rudder deflection depending on the hull, speed and course. My old Crackerbox had about 3/16" deflection each way at the back of the rudder, some of my larger hydros have over 5/8". Use what you need, but no more. Excess rudder movement leads to over-control, spinning out, hooking, etc.
