When looking for a tow vehicle, as mentioned by other, small cars are fine for beach cats. Major things to consider are the maximum GVW for the car and manual vs. auto tranny.

The GVW will indicate the ability of the car to stop the weight of itself and the trailer. A 5 passenger car full of people and baggage has to stop about the same weight as a 5 passenger car with only the driver and a medium sized beach cat.

Transmissions. I like manuals on cars for towing as I do not worry about overheating them as much as I would with an auto. With the auto you are constantly demanding more power for the extra weight which heats up the oil faster. And, you are probably going to be shifting gears quite often which wears out the tranny much faster. You also have more positive control with the manual.

Just my 2 cents.
