Trying to get back to the original question....
The build log shows quite a lot of the techniques and tools needed...
As well as the kit - if you want to sail the boat, you will need a motor, propeller/propeller shaft and connector. I don't know if a prop/propshaft comes with the kit...
If you want to control it with radio you will need a radio transmitter, a receiver, a servo and an electronic speed controller (ESC)
Someone might like to start talking about glues? and paints?
You will need a building board, modelling knife, small saw, vice, small file....lots of pins and clamps would be a good idea....
