A family member recently bought his first RC boat. Just as I recommend in Best RC Boats for Beginners, he got "a ready-to-run electric sport boat with a deep-vee hull design." Specifically, it's the Traxxas Blast, one of the models I suggest for beginners. It's just the right size for large swimming pools -- like at his apartment -- but can also be taken out to a pond or lake. The only real issues he's had with the boat are that it has no reverse -- so you better slow down and start turning or leave plenty of room for drifting to a stop before hitting the side of the pool or other obstacle and there was a little problem with water. The electronics are waterproof so that's not an issue, but it still kept getting water inside the hull. We addressed that problem with a quick fix of silicone.
