[J22-Fleet 1] Waterline Technicle Bulliton

[Smith, Craig A]

When Beth bought J22 hull #444, the seller handed us the two-bolt
lifting eye, described it as an "upgrade," and said we could install if
we wanted to.  The forward bolt was too short, so we did nothing.
 
Kudos to Jon Munson for explaining this is a mandatory "recall" item.
He added a "coupling nut" (an oversized nut into which a 2nd bolt
extends) that allowed the keel bolt to be torqued AND the two-bolt
lifting eye to be attached.  
 
If lifting on 1 bolt, be sure the bowline (from lifting strap to
foredeck cleat) is tight.   Too much bow-down will side-load the bolt,
potentially to the point of failure.

Hi There,
 
Rich, Thanks for the heads up on the keel bolt torque numbers.
As I recall my old boat had two different sizes of keel bolts.  Not sure
the exact sizes. I used to use an old tire iron to tighten my keel
bolts. I did not know the numbers I just made sure they were tight. If I
understand your last post I think you are saying "torque to half of the
numbers on that chart"?
 
I should have included a little more information when I copied and sent
the Waterline Technical Bulletin to everyone.
 
As I understand it a J22 fell from the hoist in Annapolis during the
NOOD regatta the same weekend as the Cool. I do not have any solid
information only rumors. I think the boat was the old style where the
lifting eye is attached to only one bolt.
If your boat has not been upgraded to a two bolt lift point you are at a
greater risk of having a catastrophic failure. If the boat falls from
the hoist it could kill or seriously hurt someone near or under the
boat. Please update your boat to make it safe.
 
I have been in most of the boats in our fleet during various measuring
procedures and have seen many boats that have water in the sump all the
time. This can also lead to corrosion and keel bot failure.
Keep the water out of the sump. Pull up the floor board at least once a
year and make sure the weep holes are all clear so you can sponge out
the sump from the center hole. And  most important get a two bolt system
for you lifting point.
The life you save might be your own.
