Adding a propeller makes a huge different to my little speedboat!
Miss-chief still isn't the fastest model on the water, but she works well enough for me and is a really enjoyable sail. Even in cross-winds, the top seems to stay put and no water found its way inside.
I'm not completely finished though. The rudder is the wrong shade of red, a brass prop has been bought to replace the plastic one, and I have some vintage design advertising logos for extra decoration.
Watch this space.
