I have a 5000# tandom trailer I would like to setup for an '84 C25 swing keel. This trailer has 6 upright supports adjustable for height and width and can be set up with either bunks or pads. I also need to know how far from the center pair or supports to mount the winch tower on the tongue. The trailer has an 8' 2X12 keel board that extends from the rear frame and an 8" keel roller on the center of the rear crossmember. Any information would be greatly appreciated.

Ned - I would hesitate to use the trailer you have for a Catalina 25 unless you do some upgrading. 5000#GVWR is not nearly enough capacity for a C-25 of any vintage, even the early "light" models. Even the 7500#GVWR trailers are often seen to have warped axles. If I was ordering a new trailer for a Catalina 25, I would specify 10,000#GVWR. This gives you considerably heavier-duty springs, axles, and brakes, plus a Dico #10 coupler with a 2-5/16" ball size. A 5000#GVWR trailer will have a too-small coupler, probably too-small brakes, and the frame might be made of too-small size of channel iron or tube steel.

(IMHO)Larry is absolutely right. If you are looking for a means to move your boat around your club or for a very short none stressful trip you will probably be alright but it would be patently irresponsible to endanger the lives of other people on a highway or the passengers of your car by actually “hitt’n the road” with a 5000# trailer.

5,000# capacity is not enough for a C-25. 7,500# should be the minimum. 10,000# would be better.

What

Earlier C-25s are built lighter than older models

First I've heard of this too, Buzz, because both the older and newer brochure states the same design weight...must be a MK I Mod IV Rev 2 Chg 9 model.

A few Catalina 25's in our club have been weighed on a local truck scale. These include a Mk. I, an Mk. II and a three Mk. IV's. Judging from this admittedly small sampling, it seems like the Mk. I's and II's weigh about 5000#, the Mk. III's and IV's seem to be 500 to 1000 pounds heavier. Of course, this could be due to other factors, like amount of cruising gear on the boats. One thing that seems certain is that the inboard diesel adds about 400 pounds over and above what the same boat would weigh of it had an outboard. Two of the Mk. IV boats we weighed on the truck scale are diesels, one was 9500# (boat and trailer), the other 8500#, and my own boat with a Honda 7.5 outboard, was 7600#. If you subtract 1600# for the trailer, that leaves the boat weight at about 5000# for an outboard, and 5600# for a diesel. It's hard to nail down the weights precisely, because each of these boats had differing amounts of cruising gear aboard. My own boat was "stripped" when we weighed it, whereas the 9500# boat has a lot of extras aboard, including a bank of 4 very large and heavy golf-cart size gel-cel batteries that probably weigh 100 pounds apiece.

I would have to think that the weight difference was due to individual load and not due to early model C25's being built "lighter" because I seriously doubt a yacht designer such as Frank Butler would miss a 500-1,000lb change in weight(almost 25% of design weight?).

Cruise over to the C-22 site and look at their wiegh in data from the nationals, 25% is not out of the question!

After comparing the boat weights from the 1996 nationals at the C22 site, it appears that even the lightest C22 listed (2,130lbs) is only 120lbs less than the advertised swing keel design weight of 2,250lbs with the heaviest boat being within 14% of designed displacement.

So based solely on stats from that site, a 25% weight difference between actual and designed weight IS out of the question.

Sorry, Frank, for being so ana...I mean literal, but I was responding more to the "even the early "light" models" remark than what you said.
