On a recent haul out I asked the TravelLift operator if his weight
scale read the displacement of my foriegn built sloop. He said he had
two scale's - one for each strap on the lift and by adding the two
weight reading's I would know the vessel displacement. It added up to
about 10,000lbs..

Would that be a correct way to weigh a boat? Thank's.

They're not real accurate, but for larger boats they're the best bet
you've
got.


That's what I found out when I talked to a travellift operater. I think
they are probably calibrated at the factory and never again....my guess
would be +/- 10% or so.
