I would like to tow a small boat with my CTS. Where can you get a tow hitch and how much weight can you tow safely?

From pages 4-30 to 4-42 of the Owners Manual:

How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (450 kg). But
even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a trailer are all important. It can also depend on any
special equipment that you have on your vehicle,
and the amount of tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue” later in this
section for more information.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted form the maximum trailer weight.
You can ask your dealer/retailer for our trailering
information or advice, or you can write us at our
Customer Assistance Offices. See Customer Assistance
Offices on page 7-5 for more information.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. If you have a lot of options, equipment,
passengers, or cargo in your vehicle, it will reduce the
tongue weight your vehicle can carry, which will also
reduce the trailer weight your vehicle can tow. And if you
tow a trailer, you must add the tongue load to the
GVW because your vehicle will be carrying that weight,
too. See Loading Your Vehicle on page 4-22 for
more information about your vehicle’s maximum load
capacity.
If you are using a weight-carrying hitch, the trailer
tongue (A) should weigh 10 to 15 percent of the total
loaded trailer weight (B).
After you have loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights are
proper. If they are not, you may be able to get them right
simply by moving some items around in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper limit
for cold tires. You will find these numbers on the
Tire-Loading Information label. See Loading Your
Vehicle on page 4-22. Then be sure you do not go over
the GVW limit for your vehicle, including the weight
of the trailer tongue.

Hitches
It is important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a few reasons why you will need the right hitch. Here
are some rules to follow:
• The rear bumper on your vehicle is not intended for
hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a frame-mounted
hitch that does not attach to the bumper.
• Will you have to make any holes in the body of your
vehicle when you install a trailer hitch? If you do, then
be sure to seal the holes later when you remove the
hitch. If you do not seal them, deadly carbon
monoxide (CO) from your exhaust can get into your
vehicle. See Engine Exhaust on page 2-47. Dirt and
water can also enter the vehicle.

Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer so that the tongue will not drop to the road if
it becomes separated from the hitch. Instructions about
safety chains may be provided by the hitch manufacturer
or by the trailer manufacturer. Follow the manufacturer’s
recommendation for attaching safety chains and do not
attach them to the bumper. Always leave just enough
slack so you can turn with your rig. And, never allow
safety chains to drag on the ground.

Trailer Brakes
Does your trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes so you will
be able to install, adjust and maintain them properly.
Because you have anti-lock brakes, do not try to tap into
your vehicle’s brake system. If you do, both brake
systems will not work well, or at all.

Trailer Wiring Harness
All of the electrical circuits required for your trailer
lighting system can be accessed at the driver’s side rear
lamp connector. This connector is located under the
carpet on the rear corner of the trunk compartment.

Basically, don't tow with a Cadillac CTS. :)

That's what they make trucks for ....:thumbsup:

Shame on you. No towing with the 08 CTS,Motor Trend's Car Of The Year. It is too beautiful.

If you are very careful, you can buy a Jet Ski and trailer tht will go about 800 pounds.
You can probably find a 14-15' sailboat (like a sunfish) that with trailer would be abput 600 pounds.

But like the Owners manual points out.......you don't want to do thisin mountains.

Other than a 14' boat ith <>20HP Outboard, I don't see a powerboat capability here

I to am looking to add a trailer hitch to my CTS. I have a stand-up JetSki on a small trailer which weighs maybe 600lbs. I hate driving my SUV to the lake (where the JetSki is stored) only to need it for 10 minutes to put the JetSki into the water. This would also be great for my hitch mounted bike rack.

My biggest concern is the ugly square tube hanging behind the car.

From what I have seen both Draw-Tite and Hidden Hitch both have tow hitches for the 2008 CTS.
