Tom is a thirteen year-old whose father is a Naval Officer on the half-pay list. This dates the events, for Tom has read two of Captain Marryatts books, which were published in the 1830s, while his father would have been recalled to duty in time for the Crimean War, so well put the date down as the 1840s.
The action starts in the West Indies, where Toms father has bought a property. Tom has an accident on his way to meet his father on the way from a short visit to another island. Tom is to be sent to an English school, and on his recovery he is taken down to the harbour, and put in charge of a ships Captain.
The journey back to England has every misadventure that can be thought of, including a White Squall, which we would probably today call a Line Squall. The vessel is capsized. How do they recover it?
Eventually they arrive in England. And that is the end of the story, which really is an introduction to ships for young persons of about thirteen years of age.
It isnt too long, and youll enjoy it.
