Keel Lifting Post (Danger)
« on: September 30, 2008, 07:39:41 PM »
Hi All,

A couple of weeks ago, I lifted my boat out of the water with a crane to do some bottom maintenance.  The good thing is that I am still alive to write this. The bad news is that Goombay suffered some damage. 

Inside the keel well is a backing plate made of G10... You will see a picture below.  The two main bolts attaching the keel lifting post to the boat at the keel box is threaded into this G10.  If you look to the left of the picture the 2 holes close to the edge is what was supporting the entire weight of the boat.  No washers or nuts are in place (This is not through bolted )  The threads let loose and the boat fell.  Luckily the boat was still over water and the deck stopped the boat from falling completely.  The deck did take some damage but Goombay is being fixed.

Suggestion, if you use crane launching a lot, you may want to install an inspection port on the aft end of your keel box and put through bolts in place for safety.

You will also notice that the two holes that are in the middle are supposed to be for the inserts for the scotty bolts to be tapped into.  These were never drilled in far enough. 

The G10 Plate you see was just laying inside my keelbox as the adhesive was dry and brittle and just let loose.

I will take more pictures as the repairs continue.

Hey Greg, 
Thanks for the heads up.  We hoist 'Velocitize' twice a week, at a minimum.  After completely rebuilding, the compression post at the front of the keel box last season after it failed at the SD NOOD's last year, I will have to be sure to add inspection ports to the rear of the keel box.  Might be a good use for the original forward inspection posts I replaced.

Glad to hear you weren't hurt when Goombay dropped!

The main keel lifting post is back in place, the deck has been repaired.  Things are looking good.  I am still on target for getting to Lake Norman in November!

Wow that was fast.  Did you do the repair yourself ?

Yes, I have been doing the repairs myself.  It pays to have the boat at home and in my garage.  I can work on it each day after work.  I need to take it and put it in the water to put the keel hatch back in and then the rest is just cosmetic.
