Regarding jack stands vs cradle. I have a cradle and I like that it seems to be the most secure way to store my boat during the off season. I will say that owning a cradle does have a few draw backs that are worth considering.
>When bottom painting it is difficult to reach the places where the cradle pads are. We usually have the yard guy hang the boat in the sling so we can finisn these places.
>We have not had to pay for storing our cradle during the summer, but it has been mentioned to us that we may incure a fee for storage.
>Lastly, we moved to a new moring location and had to pay $130 just to move the cradle a few miles. This really did not sit well with me as it was a very simple task for someone with a truck to do.
something to ponder

Can you post a picture? It would help.

As SF alluded to, if there's a moulded keel stub and everything's in line, then it should be OK and moving/replacing the front bolt won't accomplish anything.

|tommays||On a LOT of boats the bolts are staggered to spread the load aroumd the keel sump and as such will not be on center|

The only way the front bolt could be off centre is because of keel stub problems. If something was hit it would try to drive the keel's aft end into the hull. The total number of bolts would limit its movement. If it's off centre I would look at the keel stub - is it wood cored as some are? If it's solid glass there is not much chance of the keel moving off centre. I think that replacing the front bolt will not be the solution by itself. You have to find out the cause of the problem to find the right solution.

|ahab211||thanks for the info . I tightened them today and they were loose especially the front bolt. i have bigger problems then that as the front bolt is off center in the bilge and the keel is also off center at the front. I don't think there is a quick fix for this and I might sail it as is as the only alternative is pull of the keel and replace the front bolt. Any other ideas? thanks ahab211 Also was the weight on the keel using jacks the marina provided adding to the loose bolt problem?|

Says 3/4" bolts (1 1/8" socket) should be 250 foot-pounds.
Ask this question on their forum.
Lots of knowledge and helpful lot.
May save you some grief in the long run!

|ahab211||Thanks for te input. I'll check out the C@C website. I'm taking the advise to tighten the bolts from experienced sailors who have owned a C@C24 and bigger C@C's. I'll purchase a wrench today and report on what I find. Thanks again.|

First, how did you determine that the bolts were loose? If it's just because of the crack, then the bolts are most likely tight. The torque should be checked either way.
Many years working on cars has taught me to start looking hard at any bolt that loses torque. If a bolt loses torque, something has changed. The question is, what? On a set of keel bolts, there are only a few logical reasons.
Bolt stretch. Did the bolts stretch, and if so why? On a bolt that size, the only way they could stretch is if they are corroded most of the way through.
Bolts pulling out of the keel. Again, Why? This is a very unlikely event, but one to consider if no other cause is found.
Keel stub problems. If the keel stub is delaminating, or has voids in it due to osmosis or poor layup, the bolts may be loose due to compression of the stub at the bolts. The picture below is due to keel stub problems, although I'm not good enough with fiberglass layup problem diagnosis to say exactly what the problem was.
