snip When I'm sailing, I live by the motto "If you THINK it's time to reef, It's time!" I'm wondering if I should do the same for the keel. That goes double or triple for the keel ;-) If you don't reef and lose a rig, you have to motor home. If you lose a keel, you go swimming - or worse. Steve |

While people are on this subject..... would anyone care to give their advice when they think a keel should be rebedded? If you can feel any motion of the keel, then it should be removed, rebedded, and rebolted. I have a Cal 28 with a bolted on fin keel. About 5 years ago I grounded the boat. It was nothing serious, but over time the keel has shown more and more signs of movement. Probably doesn't have much... possibly not anything... to do with the grounding. It's the nature of the beast. ... Initially the crack between the keel and the fiberglass stub extended back about 1 foot from the front of the keel on the port side. The second year it was about two feet and so on. This year the crack extends the length of the keel and I'm thinking I need to have it done now. Yeah, if you've got a crack the whole length of the keel root you chould have done it years ago. You're sailing on borrowed time! Think about the impulse loading of the keel root when it thunks from side to side, every time you go over a wave. OTOH you've got it better than some people, whose keel bolts are inaccessible under solid fiberglass; or people with encapsulated keels that might also get wobbly over the years, or have a keel root that is getting wobbly. It's all fixable but it's also a PITA... costs money too. When I'm sailing, I live by the motto "If you THINK it's time to reef, It's time!" I'm wondering if I should do the same for the keel.

I'm wondering if I should do the same for the keel. I think it's time but wanted to know what others thought. Also, if anyone knows how much I should expect to pay my boatyard to do the job. All reply's would be much appreciated. Frank "Basil P" wrote in message .. . I have to drop my keel after a hard grounding this past season. The boat is a 34 fin keel boat with a glass keel sump that the keel is bolted to. Lead keel, S.S. bolts 1". I have a couple of question. Having never done this before I am looking for advice, not abuse. So Glenn if you are listening... What bedding compound should I use? Should I leave the seal flexible? Or could I Glass over it with a couple of layers of biaxial cloth and epoxy? Any other tips would be great. Thanks, After I drop the keel I plan on grinding out any cracks and or delamination. Then laying down more glass and epoxy. I have some Kevlar matte. I would like to know if this would be good to use under the keel bolt nuts? Or should I just stick with regular Glass? Also, would it be a good idea to use larger backing plates under the keel bolts? Instead of just the 2" fender washers. Maybe a S.S. plate that would span two or more bolts. There are (10) 3/4" S.S. bolts with 1 1/8" nuts. I will lay the glass down let it set. Drill the holes again. bring the keel back to the hull. Tape the threads of the keel bolts.Then place some thickened epoxy in the area of the plate. Wax the plate really well. Place it over the bolts and draw it up slightly. Then let it set up. Then torque to spec. This should give it a good even, flat area to carry the load. Finally. Any opinions on glassing over the hull to keel seam? Maybe using the same Kevlar matte. Extending the matte vertically 6-8" beyond the seam. Thanks again, |
