All the fastest RC cars are electric.
Comparing boats to cars is not very helpful. Cars move through air, boats through water. The density of air is 1.2 kg per cubic meter, that of water 1000 kg per cubic meter. So the dynamic resistance in moving something through water is 800 times larger than that in moving the same thing through air.
