The Voyage of the "Dauntless" - J.C.Western Holt
When his livelihood is threatened by the unscrupulous dealings of a ship-owner the captain of a small cargo vessel decides to take action. The owner pays him off in Hull and then replaces him with a captain who is prepared to see one of his ships turned into a "coffin ship" for the insurance money. A stowaway intervenes and saves the captain's life and the two of them steer the ship back to Hull and rejoin the original
crew. At this point the good captain decides to take advantage of the crook's plans and take over the ship himself. Believing it is lost, the world does not realise that the honest crew have set out for Africa under false colours.
