Below are examples mostly of his marine and naval paintings. Unless he was commissioned to feature a particular ship, his sea paintings featured a lot of water and sky, whereas ships, land and other objects usually occupied small amounts of art canvas real estate.

This exhibits a poster style, but I don't know if it was actually used for a poster.
A contrasting, more painterly style.
This is an illustration.
The sky is vast and the Harts are small.
Nowadays, pilot boats are usually a lot bigger and fancier than this.
