Site Description The Challenge is understandably in a broken condition since it sank due to boiler explosion and fire. The two historically significant engines are mounted on wooden bases. The fire tubes of the exploded boiler are visible in the model. The sides of the ship are collapsed but the fantail survived. The two propellers are mostly buried.
