In 1974 Catalina listed the 27's displacement at 6550 lbs (I've seen a few other numbers as well) but at her last haul-out, Essorant weighed in at almost 8000 lbs, a gain of nearly 23%. At the time she had all of our gear, the furniture, eight sails, two full gas tanks, bunch of crap in storage, etc. The stuff does add up.
Other displacements I've seen:
At 6240 listed, the gain would be 28%.
At 6850 listed, the gain would be 17%.
I understand that manufacturers often listed the displacement of the hull, internal structure, ballast, and rig with just about nothing else inside the boat (no motor for example), for racing ratings purposes.
