Steam yacht
From Tardis Wiki, the free Doctor Who reference
A steam yacht was a type of steamboat.
While travelling to Southampton, Henry Palmerdale's steam yacht became caught in a blanket of fog. With the lighthouse non-operational, it struck against Fang Rock. Palmerdale was quick to abandon the ship and had insured it.
Harker, the yacht's bosun, secured the boat but refused to take it out on the water again, despite Palmerdale's protestations, as the poor conditions persisted. (TV: Horror of Fang Rock)
