Aaron:
 
Not long after acquiring my C&C 30 Mk 1 #19, while sailing on a blustery day, I 
thought I could see movement in the chain plate above deck when a puff hit.
 My son inspected closer and confirmed the chain plate was moving. When we 
later removed the panel outboard of the dinette table, we saw that perhaps the 
lower 4 in. of the chainplate knee's tabbing was separating from the hull. I 
had a professional re-glass
 the tabbing of the knee. 
 
Considering that you are getting water on the inside of the tabbing, you should 
check for the integrity of the wood core of the knee. Short of drilling some
 holes into the knee, I would probe the wood to see how firm it is. This can be 
done by either removing the chain plate entirely and checking at each bolt 
hole, or if you do not want to remove the chain plate, remove individual bolts 
randomly and probe with
 a pick. One telltale sign is if the bolt holes in the knees appear to have 
"stressed" and are not perfectly round.  If you have soft or decaying wood, you 
should consider replacing the knees. If you have firm wood, you might want to 
coat the inside of the
 holes with epoxy (use a Q tip) to help seal the wood at these penetrations 
before you put things back together. Obviously seal the chainplates at deck 
level as best as you can.

Good Morning,

What is the proper procedure the make sure Chainplate Knees are in good 
condition on my 30-1? They look and sound solid but on a very rainy day, I 
noticed that about a foot under the knee
 (behind the seat back) where the overlapping pieces of glass reinforcement 
ends, There is very small of water seeping out from underneath the glass. It's 
only noticeable if I use a brown tissue paper. I know that I have to reseal the 
chainplates but I have
 been putting it off to next season. Does anyone have any experience with the 
knees on a 30-1?

 



Cheers,


Aaron R.
