The speed of RC boats really depends on the particular boat you are talking about. There are many different makes and models, and they are not all created equally. So while some models might provide you with top speeds, others might simply cruise along and give you an opportunity to learn a few cool moves on the water.
Because you will find sailboats, speed boats, and submarines, you can obviously find a number of different speed and trick variations. Some sailboats might not go very fast but they can be controlled in a way that it looks as though they are dancing. While speed boats can go pretty fast, they don’t necessarily offer anything other than that speed in terms of visual enjoyment.
You may decide that you want to have a number of different RC boats so that you can have the opportunity to experience what each one has to offer. It can quickly become an enjoyable hobby if you are looking for something to do in your spare time. It’s also a great way to spend some quality time with friends or family.
