Trailered Weight and Clearance under Radar Arch, etc

More questions from the "newbie" ref. CD-25

I have gotten estimated trailered weights from several sources, but figured the best info would be from those who have trailered and weighed their 25's.

To my thinking, the largest contributors to the total weight of the package is the boat, itself, the motor or motors, fuel, water and the trailer. Thusfar, the total seems to well within the 7400# capacity of my 4wd Tahoe. I have decided to go with an aluminum trailer, which saves about 500+#s. What weights have owners of the 25's found to be the actual figure?

A radar arch is a necessity for me, since I plan to have the radar dome, anchor light, gps receiver, plus 3 transmitting antennas mounted on it. Operating on marine vhf as well as at least seven additional Ham radio bands should prove to be an exercise in rf mayhem--yeah I know that proper grounding and breaking up rf loops with toroids will occupy me for weeks. Luckily, the Ham activities can handled with only two antennas.

It finally dawned on me that my plan to slide a dinghy under the arch may not work. Most small, inflateable dinghys have tubes in the 16" to 18" range. Does anyone know the clearance between the cabin roof and bottom of the radar arch on a 25? It appears that there is about 2" more room at the sides than in the center. So what options have others come up with? Partial deflation, moving the arch forward and how much room would that leave me to stow the dinghy?

Remember, I live in Cincinnati and have never seen a CD 25 on the water. Of the three 22's I have seen here in the midwest, none had arches. As far as I can determine, there are only two 25s within 500mi and the dealers with them have little more knowledge about these particulars than I do. C-Dory has told one of them that the trailered height to the top of an arch will be "less than 11'6", and I suspect that figure is pretty accurate. I am guessing that the additional height of items that cannot be readily folded over or unscrewed will be less than 2 ft.

So all help is appreciated--just remember to be gentle!

Ed, the clearance between the cabin roof and the bottom of the radar arch can be whatever you want it to be. If you want greater clearance, just have it constructed acccordingly. (Obviously, if you get the overall height too great, you may get stuck under a highway overpass... :crook )

Perhaps, some of the 25' owners with arches and dinghys can provide you with the measurements that work for them.
 
My CD-25 weighs 7,400 lbs, twin Yami 80 4 strokes, full fuel (100 gal), 1/2 tank water, 2 batteries, ice chest, normal food supplies, utencils, pots/pans, 2 anchors/chain/230 ft rode on bow anchor, no hot water heater, no shower, galvanized Pacific 27 ft trailer (approx 2,000-2,100 lbs) w/spare wheel/tire.

My '03 Expedition is rated at 8,700 lbs (4x4), I wouldn't want any more weight to pull. A word of caution, that tow rating includes not only your trailer/boat but you, your passengers, tool box, and any additional gear carried on the tow vehicle. The Tahoe in my opinion is very marginal to tow a CD-25, even with the aluminum trailer, you're right on the edge, including wheelbase. It'll probably work for short tows, no heavy duty hills, but will put a fair amount of stress on the tow vehicle, transmission and other components.
 
On the raft situation, I trailer and cruise with my 8' 6" raft rolled up and tied down on the bow. If I want to move around after it's inflated, I simply turn it around and put on the roof with the rear pontoons surrounding my radar on a power strut, then tie down using the roof rails. Of course I don't have a bazillion antennas up there either...!

Good luck with your configuration, think it through, some like the arch at the rear of the cabin to allow putting the raft on front to rear -- don't have to lift above your head like I do.
 
Interesting on the 7400#. That's about 2000# more than I had come up with using figures from C-Dory and the dealers.

I forgot that the arch was not factory supplied, so have no idea of the actual height of the arch, itself. Guess dinghy selection will have to wait.

Our research on our CD-25 has us thinking around 7500 pounds on the trailer. We were originally thinking that we would tow it with our Class B van with a tow rating of 8400 pounds. As has been stated, that weight also has to include the weight of passengers, fuel, and stores in the tow vehicle as well... we could see that we were going to be overweight significantly. Thus, the new diesel pick-up for a tow vehicle (with over 15,000 pound tow rating).

Here is a shot of the CD-25 at the Seattle Boat Show.

We didn't measure the height with the arch, but it appears to have at least 18" between the bottom of the arch and the cabintop. We have a 8.5' Zodiak/WM inflatable that we intend to carry up there; seen plenty like that in the photos section. Add the diameter of the bars, any accessories, and you should get pretty close. HTH

Best wishes,

Ed,
We also tow our 25 with an '03 Expedition. Configured with a Honda 130 and Honda 15 kicker, we're also close to 7,500 lbs loaded. I second the opinion that I'm maxed out with that load. I have taken trips of 1000 miles with no repercussions, but if I was towing all the time I would want more capacity in my tow vehicle.

We have the "tall" radar arch. I know that they can be any height, but there are short and tall standardized versions now for the 25. There is 17" of height under the tall arch, so you can stow a small inflatable under it.

Nice photo @ Seattle show. Is the color stripe black, as it appears in the picture? Is that the factory "tall" arch?

At last I have some more definite info to use. Looks like a heavier tow wil have to be in my near-future plans. Many thanks Steve, Lyle and Jim B.

Ed, I forgot to say that 7,400 lbs is WITH the trailer (and spare wheel-heavy), that's probably the extra 2,000 lbs you're looking for.

Jim, nice pic of the CD-25 at the show. I love the show lights and how they reflect on a good-looking boat. This one is a Green accented model just like mine...thanks.
 
The arch in the photo is the taller of the two offered by the factory. The boat is actually green, but the lighting in the boat show area didn't allow that subtlity to come through.

And, a question for Lyle regarding the Honda 130: when we discussed our intended usage, Jeff suggested the Honda 135 for us. What are you getting for real world top speeds? We will be using the boat for cruising and don't realistically see us running the boat at the top end very often (both for comfort AND fuel economy). I think I understand the differences between the 135 and 150, and it sounds that at lower RPMs they are essentially the same. Have you run with any other 25s with the 150? See any significant difference?

Thanks for any insight you can offer.

Best wishes,
Jim B.

You also need to remember that the max tow rating is with a weight distributing hitch and MOST boats don't use them (interestingly my 27' uses one).

That Tahoe is definitely too light for your setup!
