If you are a reasonable woodworker, you will already have the tools, but since you are asking, I must assume otherwise. For a first, look for something relatively unambitious. If it is a plastic kit, you get the chance for a result without too much hassle because the hard bits are pre-done. You get to learn how a boat goes together and what is needed to make it work. Then go for something bigger.
Or search for "Springer" tugs. Simple, very basic tools, tough when built.
