Thanks. Appreciate the response. I've seen these charts, too, but then I see all kinds of complicated formulas for the actual torque you need for a given, what is it?, clamp load or preload, which I interpret as the weight that the bolts are holding (i.e., the cast iron keel, in our case, which is 10,300 lbs according to my specs). The number of bolts is a factor, too, right? I assume, since we have the same model boat, that you have 3/4"-10 UNC S/S bolts (looks like you have coarse thread, like me), 10 in number. I also have the channel backers, although they are galvanized steel, so I'm not too worried about crushing the laminate (I don't think). I'm just looking for a number in the range I would be going for so I can invest in a proper torque wrench. Since you've evidently done it, I was hoping you could give me a number. Did you just use the 128 in the chart then?

Another question, if you don't mind, the four forward bolts are extremely difficult to get to on my boat. How are they on yours? The ones you picture, like mine, are easy to access. It would be virtually impossible to extract any of the forward four because there would be no room to pull them out (well, the ones next to the mast might be extractable).

Anyway, I do appreciate your response and would appreciate any more info you might have. Would like to check my bolts' torque and see how far off they might be.

Thanks.
