Hope you're on the hard
If you want to check it, be sure you're hauled out first. The weight of the keel will not allow for adjustment. If you have the keel on the ground and stable, you'll have better luck "checking the torque". I have to wonder why you're doing this. Is it cuz of the famous "Catalina smile"? If so, tightening the keel bolts won't necessarily cure the problem. LaDonna
