Ballast in Displacement?

[joel]

Travel lift scales are not terribly accurate.  Our 49 weighed 38,000 on the travel lift without the mast, same on a truck scale with the mast. Published weight is 32,000. Water tanks were empty, fuel was about 75 gallons.

I will try again.  My messages keep getting cut off. 
 
I doubt that is correct.  The listed displacement for a H54 is 48,000lbs or 24 tons of which 20,000 is ballast.

At my last splash the travel lift guy reported a weight of 62,000lbs. She was loaded with the normal stuff; dinghy, sails, clothes, tools, spares etc,  but not packed full, empty water tanks but 230 gallons of diesel diesel. 

I think the video probably showed a travel lift with a 30 T limit, and that H54 probably was just over that if she was loaded for cruising.

Personally we always try to use a 50T lift minimum, preferably a 100T+ lift.   But sometimes its just not available.

I was recently watching a Hylas 54 get hauled when the lift operator suddenly stopped (keel was still in the water) and said that the boat weighed 10K lbs more than the advertised 50K displacement weight. He claimed that with Hylas's (and Tayana's and Moody's), the ballast amount is not included in the displacement figure.  This seems odd to me as I always thought ballast was included in the displacement figure. Can anyone elaborate? BTW, owner said boat had empty tanks.
