I replaced all the washers on the keel bolts on Alianna with 3/8 stainless plate. The keel bolts may need to be torqued, including the one under the mast. Before torquing the bolts, depending on how serious the leak is, (like is the bilge filled with water now or if it were full then how bad would the leak be) you may be able to grind into the joint on either side back aft as far as you have to and force some compound into the joint after you clean it out. I did that on my 35 MKII and I filled the cavity I created at the joint with 3M 5200. That will prevent leaking from the outside into the boat after launch and when you torque the keel bolts and replace the washers with something more substantial or use at least 2 washers per bolt you can also put compound (4200 0r 5200) around the bolts where they come up through the hull I used a lot so that it squished out all around as I torqued the nuts. That was 8 years ago and no problems. Torque Specs are on the cnc site. You will need a ¾ in drive and some large (I think 11/4 and 11/2) deep sockets and about a 1-2 foot long extension on the drive and a force multiplier on the socket handle I used a 4 foot long section of steel pipe dont jerk the socket, just steady pull and when you use the pipe extension you only have enough room for one click on the ratchet at a time I would expect the keel bolts to be fine and the nuts too I would definitely try that before doing a total removal and re-bedding of the keel On the outside, after the 5200 cures a bit you can fair with car body filler or you can epoxy over the entire joint with glass reinforced epoxy and then fair. _____ From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of andrew rothweiler Sent: April 24, 2014 2:35 PM To: cnc-list@cnc-list.com Subject: Stus-List (no subject) Hello all, Just returned from the trip to look at a C&C 35-2. I only saw two things that concerned me (I'm no expert of course and I'd have a thorough survey), and I'm writing too ask people's opinions on these two issues. First, at the keel to hull joint, directly under the mast, there was water weeping through the joint onto both sides of the keel. Also, if not mistaken, I believe that the forward keel bolt, which is under the mast and can't be seen unless the mast is removed, is in this location on a vertical plane. Is this weeping at the hull/keel joint a serious concern? (i.e. is it enough not to waste money on a survey?) Is it likely that there is water running from the bilge or through the mast, past the keel bolt under the mast (hence a potentially comprised/rusty keel bolt under the mast?) and coming out through the joint? 1) the owner has had the boat shrink wrapped and on the hard for the last three years, and told me that winds this winter have blown the shrink wrap off the boat, and this spring is the first time the weeping has occurred. 2) The entire hull keel joint looked to me to be very good or excellent, no smile visible, and the bottom looked pretty smooth with a near perfect coat of fresh bottom paint. Second, the washer on the center (lowest in the bilge?) keel bolt was extremely rusty. The other visible keel bolts and washers looked very good. I don't remember if the center keel bolt itself was rusty. Also, the gelcoat surface of the bottom of the keel was spider cracked pretty thoroughly, I thought at the time that this was superficial and cosmetic. Are the rusty keel bolt washer and the spider cracked surface of the bilge potential areas of concern? Thank you in advance for any guidance here.
