C22 weight
The specs page at this site lists the displacement of a 22mkII at 2290#. Typically, displacement is the weight of the craft loaded at waterline, crew, gear, etc. However this list also gives a capri 13 only 138# displacement. Therefore I would say 2290 is the boats empty weight! As to towing, a friend of mine pulled his 22 with a Jeep Grand Cherokee, 4.0 engine. It would pull the weight fine but there was considerable bobbing and weaving as the trailer would surge against the truck! The 22 is not a light craft and due care should be taken to trail it safely!
