First a Sincere Thanks to All , As far as my ideas, A home slip and Trailer to lakes and coastal destinations for no less than 7-10 days each adventure. Maybe 5 trips a year. (maybe) Truck F-350 4x4 diesel swb single rear tires. Am very fit for 52 , I think I would miss the head room and pray for a breeze. Keel choice is my next consideration shoal draft has advantages for me. From what Ive read and heard Swing keel cables hum. I dont know first hand, I am connecting with locals for lessons or at least a ride. Thanks again. Jack

Swing keel cables don't hum if you loosen them enough. But there are some of the brethren here who like the hum -- it assures them they're actually moving, or something like that. I prefer to make my own music -- and enjoy the silence of sailing.

But the swing does require regular -- annual or bi-annual -- maintenance. There are many, many threads in the archives devoted to that topic. I like my swing -- as has been noted ad infinitum.

What was the topic or question?

If it is cable hum, I'm in. Let's me know without either of my speed guages what's really happening.

The hum is the cable vibrating against the hull fitting, brass turning ball at the top of the thru hull pipe which I have replaced twice be cause of a large flat spot worn on the ball. It could have been the drag of the ball and the cable rubbing the ball but thought the vibration could be the cause. Any thoughts.

Sweetcraft .. questions:
Was the flat spot in the groove?
If so it's most likely due to the ball not turning when the keel is repositioned. I don't see it being an easy task to tell if the ball turns when moving the keel while in the water (never tried to lookup from under the boat like that.) I'm guessing that is the only way to tell.

Can it be seen down the cable tube in the cabin? Is it ok to pull off the tube while in the water (ie. Does the fiberglass tube extend up above the water line?)

Your balls are not turning and they are acting like bushings... and getting chewed in half ... just like mine.

Hi again, Jack, and since we haven't said it before, welcome!

Your answers to my questions (an earlier "Tall vs Standard" thread, for anyone wondering) suggest that you're on the right track. The C-25 is a good boat for keeping in the water and (swing or wing) making occasional trips--and you have the right vehicle. The swinger is less problematic in fresh water than salt, but still needs some simple attention every few years (annually in salt). The wing (newer models and some older conversions) might be your best option--it only draws a few inches more than the fully-raised swing and doesn't take much more to launch and retrieve. But the wing, all else being equal, will come in third to the swing and the fin going up-wind. I hear that people eliminate the hum by relaxing the cable.

Keep in touch during your quest, ask any questions, and good luck!
