[C320-list] boat out

[Jeff Hare]

When out of the water, our boat is supported almost entirely by the keel with typically 7 jack stands providing support against tipping. 

Any chance that the weight was actually NOT on the keel as you expected but perhaps mostly supported by the pads or wherever it contacts the hull?

Slings support the hull gently, but if there are a few support pads around the hull on the cradle and the keel length measurements were off some, maybe the pads were bearing too much weight?

hi fellow members
I went to haul my 320 out today on a slipway at my yacht club
Purpose built cradle on rails
 
After centring the boat we began to haul her up slowly and as the weight
came onto the keel I heard stressing noises as the fibreglass started making
cracking noises..in the area of the bilge. 
Naturally I aborted the project as it seemed to me the keel was not able to
take the weight of the boat. Had both water tanks empty by the way..
 
Now even if the yacht comes out with a 'Tammy lift' it is usually rested on
its keel so I don't get it...
 
The question...has anyone ever experienced such noises and or damaged a 320
while bringing their boat up on the slip in this way?
 
I'd suggest the angle of this slipway as about 30 degrees 
 
Love some feedback 
 
Kind regards & Thanks
