Welcome aboard!! I'm retired Navy
weight is the weight of the boat probably with no gear
on board or water
in ballast tanks
. (Dry weight) I didn't know C&Cs had ballast tanks
but I'm certain they had different versions. When you find out the towing capacity of your vehicle then you have to consider the trailer
weight, the boat plus related gear
like anchors, outboard
and stores, etc..
Hope this helps.
