What does the manual say?

Short answer: NO

The manual recomends that you do not tow anything, I am sure you probably could tow a small boat with out a problem, but the tC was not designed with towing in mind.

Darn! I looked yesterday at a tC and noticed there wasn't much of a frame in the back bumper area for a hitch. My boat is small but I wouldn't want to tow it if the manual says no. I am sure there would be warranty issues.
