Seafaring life: Author and historian Huw Lewis-Jones has compiled incredible images from vintage seafarers' sketchbooks, including this painting by Frenchman Theodore Gericault of a storm off Le Havre, France, in 1818.

High seas: The artwork on the left depicts a boat in stormy seas and is by British mariner-artist John Everett, who crossed the Atlantic several times in the 1920s. On the right is the Englishman John Kingsley Cook's "Informal pose in the Wheelhouse, 1941."

Exploring the world: Dutch pastor Jan Brandes sailed for the West Indies in the late 1700s. He produced colorful portraits of creatures, as well as life on deck, such as this one.

Arctic images: Dutch seafarer Louis Apol produced pictures depicting the treacherous conditions in the Arctic.

Early map of Venice: Ottoman cartographer Piri Reis painted the Venetian lagoon in the 1500s.

Flying fish: Seafarers' journals often included drawings and diagrams of fish and sea creatures. Dutchman Adriaen Coenen produced his "Visboek," a book of fish, while at sea. This page depicts a flying fish, found in tropical climes.

Island sketches: German surgeon Sigismund Bacstrom painted this plate: "A View of Staaten Island with a Herd of Seals." Bacstrom is also known for producing one of the earliest known drawings of a whale.

Two sides of the story: Dutch artist Willem van de Velde sketched scenes in the Anglo-Dutch War in the late 1600s -- memorably from both sides in the conflict. He worked as an official war artist for the Dutch and then moved to London, working for King Charles II.

Bathing in the ocean: British hydrographer and captain Owen Stanley sketched his crew bathing in the ocean during his survey voyage on HMS Rattlesnake in 1848.

Sketches from the sea: French fisherman Paul-Emile Pajot was known for his intricate and spectacular sketches of marine life and people.

Moments from the ocean: Here's more of Pajot's work. A multi-talented man, he also wrote poetry.

World-changing: Lewis-Jones says a lot of the images show first-hand how people's understanding of the world was changing. "That's what a lot of these big expeditions did -- change the way people see the world," Lewis-Jones tells CNN Travel.
