to add my 2 cents - the hull type is a big deal for beginners. I recommend a V-hull (off shore deep vee style) and second to that would be a catamaran.
Stay away from riggers and hydro planes, and tunnel hulls. while they are really fast setup is more difficult.
My first boat was a traxxas villain IV, it was not fast but 100% dependable. The only time I had to go get it was because I ran over a plastic bag. That's a lot more then I can say for anything else I have bought. Newer boats are faster, but I find they break much more easily, or have setup problems out of the box.
To start, simple is better. It's better to have fun driving then chasing problems.
