Hi everyone and thanks for your great advice on what to watch out for on the purchase of a C250 WB. I can now tell you that my husband and I are proud owners of "Ciao"a 2003 250 WB Hull #667. I have a couple questions regarding centerboard noises. When we are sailing there is a buzzing sound you can hear in the cabin when the cb is down. Is this normal? Also, we are not sure where the other noise is coming from, but it is kind of rattle or scratching noise....almost like a mouse which is what we thought it might be, but it never stops. We were out for a 3 day cruise last weekend & both nights we slept on the hook. We tried & tried to figure out where it could be coming from but to no avail. Could we have picked up something that is stuck up there? Anyone have any ideas? Other than the mystery noises, she's perfect & loads of fun so far!(I will send pics as soon as I figure out how!)

Carolyn, In your previous post you spoke of the centerboard klunking.
Was this reshimmed? I have never heard of your other symptoms but some one else will chime in. But my thinking is that centerboard as the culprit.

Carolyn, Welcome aboard!
Do you hear that "rattle or scratching" noise while the boat is still, like at anchor or docked? Based on you profile, I see your in Sarasota so I'm assuming your in the gulf and not a lake. I bet what your hearing are Krill. They are like tiny shrimp that feed on the growth on your hull bottom, sounds like cellophane crinkling.

Carolyn,
The buzzing sound is your centerboard line.
When it's too tight it will sing like a guitar string.
Give it more slack from the cockpit to see it helps.
Mine is a '04 C250WB.

Carolyn,

On the buzzing noise issue coming from your centerboard area:

"Nobody knows why that is" (A quote from Captain Ron in the movie by the same name.) Just kidding!

The clunking noise just means shim time for your centerboard which is an easy, cheap, on the trailer fix, by making and installing some plastic shims. While you are under there it is a good time to check out the cable, or dacron line, the block, and the brass turning block, all of which will probably need a little maintenance.
You can also give yourself some peace of mind by checking our the bolts and other stuff around the centerboard.

Hi again, sorry I didn't respond sooner,I got caught up at work for a few days. Anyway, thanks for the advice. No, unfortunately I have wimped out when it comes to going under the boat the last couple weekends...the water is a frigid 62 degrees(read: native floridian) & we've had some fabulously windy days which unfortunately have kept the water pretty churned up. But I am going to give it another shot tomorrow (mask & snorkel in hand!). We are sailing/cruising again this weekend so I am going to try slackening the cb as you suggested Russ.Johnson, thanks. The scratching really doesn't sound like cellophane crinkling, Tompotter, will I be able to see krill when I go under? We have not shimmed the centerboard yet. The only place we can get a haul out around Sarasota is in Palmetto(20 nm north) at Snead Island Boatyard, so we have to wait til' we have time to make the trip during the week when they are open. (Sarasota's marina's have almost all fallen to the hands of the condo developer's

)
