I own a catalina 22 and it scales out at 2500 plus the 1000 for the trailer then the 600 or so must haves that are in the boat that totals about 4100 and I am sure that a catalina 25 weighs a bit more i do not think that a wagon would have the capacity for that size. You may be ok down the road but what about quick stops, hills or even getting the boat up the ramp. I would thik that you would need a little more tow vehicle./If your not going to trailer theboat you can always borrow a truck or rent on the two times a year you need to tow it.Herb
