Skippers of the Kameleon (2003)

Hielke and Sietse have one dream: a boat of their own. They dream of tearing around the canals and sailing on the lake and being free. One day, their dream comes true. A boat damaged in a local tugboat accident pulls up to the blacksmith’s and through good-natured bargaining, their father buys the boat for his sons. They all work hard to restore it and the boys set out to paint it with whatever is to hand. There doesn’t seem to be enough of any one color, so they mix all of the paint together. As a result, the boat seems to change colour from every angle. It looks like a giant chameleon (kameleon)

From then on, Sietse and Hielke are the Skippers of the Kameleon!
