There are four big steps:
Making the model
Making the mould
Making the boat in polyester
Finishing the boat
I am from Belgium, so please excuse me if I make any language mistakes.
In the next clip you can see the boat in action.
Step 1: Part 1 - The model in wood
Step 2: Part 2 - Making the mould.
Step 3: Part 3 - Making the polyester boat
Step 4: Part 4 - Setting up the inside of the boat
The engine is from a hand drill.
Step 5: Part 5 - Finishing the boat
I used the Hitec Flash 5 system pack (transmitter, receiver and 4 servo's), and a speed controller of Protech of 30A max. The battery has 7 cells and provides 8.4 V. Again, most of the pictures are in the video.
Step 6: Testing the boat.
