For many years I've been wanting to check my keel bolt torque and after a light
grounding last year in anchorage, I acquired the tools and was shocked this
last weekend to find all nuts measured 35-50 pounds of torque. For my '81
C with 1" rods in the keel, the torque should be closer to

My boatyard did something similar when we replaced the keel. They prepped the
joint surfaces with the intention of glassing the joint, ground a six inch
bevel into the fiberglass stub, and the top edge of the lead keel. They
cleaned out all the bolt holes, buttered the keel joint,
Hi Charlie,
In answer to your questions:
Yes, keel bolts can be tightened while the boat is in the water or on a cradle.
Intuitively, many have suggested that the boat needs to be on a cradle with
the keel supported so the keel is not "hanging". However, a calculation of
loads and forces

This was my experience when removing my keel. We had to “break it loose” when
lifting the hull.
Question for you Rob, my keel joint had epoxy for the keel stub/keel joint
which I assumed was done by a PO when the bottom was peeled and epoxy coated.
Was it actually done at the plant?
Regards,
I have watched a number of keels removed from a hull. Most all the time the
epoxy held the keel when the nuts were removed. In fact there are special
wedges made to try to break it loose . . . . . It is a really tough job . . .

Bottom line, in my opinion, it will not matter whether the
Hi Charlie,
Sorry you have a leak. I believe you have a very unique centerboard version of
the 34/36plus. I don't know if they ever made another.
Anyway, can you see where the leak is coming from? Was the keel to hull joint
showing when it was last on the hard?
I would wait until the boat is
I am not an engineer in any sense of the word but perhaps someone on the list
can critique these thoughts of mine:
Keel bolts can be tightened on the hard (while resting on the keel) or in the
water while the keel is hanging from the bolts.
I suspect the job would be considerably easier
If the keel bolts and nuts are stainless I'd use Tef Gel as a lubricant and
lower the torque values 10% as Neil suggested.

Lower all torque values by 10% if using any lubricant. Most torque
values are for "clean and dry threads".

On a previous boat on keel bolt suffered from "Galling" (look it up). It was
at the threads exactly where the nut is when tightened and resulted in the nut
spinning and not tightening. Inside the keel there was no problem

breaking. Really, it means that something HAS BROKEN. A crack around the

I blasted out to Victoria to escape the frigid Alberta cold for a week or so.
So I thought a little biking and messing around in the bilge would be fun. The
water in the bilge was a bit salty and the mild steel plates below the keel
bolts were badly corroded so I replaced some of the plates
Sounds like a pro job to me. I would talk to Blackline and get their
