I know the Catalina 30 displaces over 10,000 lbs, but does anyone know what it actually weighs? thanks Joe

Joe Using the search engine on this 'site is great. Try the link below which I got from searching "displacement."

Weight of your Catalina 30
The weight on my documentation states 7 gross tons. As you know the actual "wet" weight varies depending on how your boat is outfitted. Water, fuel stores etc. When you haul out the travel lift operator should be able to tell you. Hopefully that answers your question. Scott

Tonnage and Displacement
The gross and net tonnage on your certificate of documentation are measures of the cargo carrying capacity of your vessel in "tons" of 100 cubic feet. Tonnage is used by larger ships for taxing purposes and is based on the cargo capacity by volume. Net tonnage is the gross accessible volume (gross tonnage)less the spaces for crew berthing, heads, galley etc. Note that to be documented you must measure at least 5 tons net. This measurement is not the same as displacement which measures the actual weight of the vessel. For large ships this is usually noted in long tons (2240 lbs) as dead weight tons (dwt). The previous note that it weighs 10,500 lbs (4.7 dwt)is probably close to the right number for the actual displacement depending on what weight you may have added. The origin of the long ton is a peculiar piece of English metrology. To the English a stone equals 14 lbs. Eight stone equals a hundredweight (112 lbs, only in English units could 112 be a hundred weight). And 20 hundred weight equals a long ton. Note the clever shift from base 7 to base 8 to base 10 at each step in the same system of weights.

C30 Displacement
The brochures for the C30s are on the Catalina 30 Association web site. The brochures give the displacement of the various models. The Mark II is listed as 10,200 lbs. with the fin keel. It is listed as 10,300 with the wing keel.
