Being that's its an audi, it might not tow so well being the fact that there city vehicles so you might have a hard time when exiting the ramp due to the pull from the trailer and the boat, i know some of my buddies can tow up to 70% of the vehivcles estimated weight, but i have seen several of those and infinity at the docks and they seemed to pull the big boats ok, not soo good gas mileage though.... would aslo depend what type of tires your gonna put on there, they might slip when wet at the lauch you know....
