What must be a silly steering question

Hello,

Long time reader, first time poster.

Over the summer I acquired 310 hull 238 here in Portland OR. It joins my Catalina 25 (now moored in Astoria OR) and is my first “big” boat. I’ve enjoyed learning about diesel inboards, pedestal steering, and all the bigger systems that were absent on my prior smaller boats.

Anyway, what does this knob do?

I assumed it was a steering brake, but tightened down fully I sense no additional drag in the steering. I was then convinced it held the wheel on, but after removing it there’s a much larger nut underneath for that. Do I perhaps have a failed brake system?

I’ve put all the combinations of wheel and knob that I can think of into the internet, and found only info about those little spinner trucker-style helper knobs for faster wheel turning, not whatever this is.

Thanks for the help.

Max

Do a web search for Edson Marine. They have lots of good info on their site. Noodle around until you see what looks like your setup and drill down from there.

The purpose of an Edson steering wheel nut is a decorative covering to allow for the removal of the steering wheel.

And the wheel brake clamp will typically be inside the top of the pedestal. Requires removing the compass to gain access, but there should be a knob (mine is on the STB side of the pedestal below the throttle lever) That allows you to tighten or loosen the brake.

Thanks all! So it look like I do have the thru-shaft brake and that it’s probably completely worn out. I’ll add rebuilding it to my long term to-do list. I’m glad the brake is so simple and local to the pedestal.

As Calif.Ted said, you will probably never use the friction brake. If you do need to lock the wheel, just engage the Ray Marine wheel pilot lock lever.

Yeah, that’s my current operating mode. I can see it being handy as a second option. I was more worried if it’s ineffectiveness was an indication of some larger problem with the steering, but it doesn’t sound like it.

I do use my brake pretty often despite having an autopilot. The AP is good for locking things in, but a lot of times I still want to steer myself, just without needing to keep my hand on the wheel constantly. One example is sailing on a beat with the boat balancing itself. In a stronger breeze there’s enough weather helm that the wheel will turn itself if not on the brake, but I still want to be able to turn the wheel to react to wind shifts.
