Russ - thanks for the west coast humour - yes we are lucky here to have our boats in the water year round - though it does have its downsides too in that the hulls never dry out and growth on the bottom continues even in the winter. The torques I applied to the 3/4 inch bolts were around 140 foot

Josh and Rob - thanks for your comments. I did torque the bolts while in the water after reading a convincing post about how little extra torque is needed to overcome the weight of the keel (think of the leverage of each bolt's screw thread). The suggestion for a much heavier keel only worked out

Status update: I ended up torquing the keel bolts. They were not incredibly loose but all of them needed tightening, two by a turn or more and the other two by less than a turn. I will know if this removed the keel movement when the boat is next hauled out, although I am also thinking of diving on

Thanks Denis for the suggestion - I will read up on torque multipliers. Joe - Thanks for your comments. The C 24 has large stainless washers (in one case quite a few of them stacked) to spread the load. I will go carefully so as not to crush the fibreglass and if I cannot approach the correct

For anyone interested, the keel bolt nuts on the C 24 are 3/4 inch at the front of the keel followed by 3 nuts that are 1 1/8". I found the forward nut (the only one I had a socket for) to be barely more than hand tightened. According to specs I found on the C owners site this should be at 80 foot

Hi Mike, Thanks for the suggestions. I will test the torque of the bolts later today if my socket is deep enough to do so. If they have not been tightened for 35 years (and the original long term owner assured me he had never done so) then maybe this is the issue. Regards, Chris

Hi folks, I own Drifter, a C 24 from 1985. A recent survey by a potential buyer found that despite the keel being well attached (no 'smile' or obvious issues with the sump to keel joint) the keel moves up to 4 inches from side to side while the boat is hanging in the slings. The surveyor
