With King George III at the wheel (declared "short sighted" by the artist), the ship of state is directed by the Earl of Bute, dressed here as a highland Scot. Beside him is Satan, tossing the lead and announcing "no bottom." This is clearly a lie, as the sailor by the mainmast announces, warning that the ship will crash on "the Breakers of America."
The sailor wears no jacket, waistcoat, but has a neckcloth. His shirt is rolled up just past the elbow, and is tucked into trousers or petticoat trousers.
