I have a towbar - as it happens the Coop is a pretty good tow car, stable, powerful (and the power is nice and smooth) and good brakes. But as a car it is light, and the max safe (braked) towing weight is about 1000Kg I think. Less is better though. A 14' boat is going to be well under that - unless it has a monster engine. Boat weight distribution is key here though - especially if it has a big outboard hanging off the back (sorry - stern) and you have left the fuel and anchor in the back there too). Get the weight distribution right (about 50-60 kg heavy at the towhitch is good), don't be afraid to put all the weight you can in the car boot and above all keep the speed sensible and you will be fine.
