I have moved several boats of different sizes with different cars, Starting with the most recent and going back...
Dinghys (various), Caravan, various trailers using a Landrover Discovery. (Noooo not all at the same time)
As above but also a wooden 21ft sailing cruiser weighing about one and a half tons... Landrover 110 Defender.
17ft fishing dinghy (quite heavy and loaded up with stuff) Citroen 19BX.
Dinghies.. Renault 4!!!
The same 17ft fishing dinghy (quite heavy and loaded up with stuff) Renault 16.
Have been towing boats trailers and caravans for 30 years now! Obviously the two landies were the best I've towed with, but even the Renault 4 did well, towing a laden 10ft dinghy from Harlow to Paignton.
None of the vehicles were 'bad' at the task but the Renault 16 was probably the least good on a power to weight ratio.
