The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was a United States expedition to explore the newly acquired western portion of the country after the Louisiana Purchase. The expedition covered approximately 10,600 miles, with 85% of the journey—over 9,000 miles—made by boat. The boats used by the expedition included a military barge, pirogues, dugout canoes, rafts, and boats covered with animal hides. The most famous boat was the keelboat, which was built in Pittsburgh in 1803 according to detailed specifications by Meriwether Lewis. The keelboat was 55 feet long, with an 8-foot beam, and a shallow draft. It could be propelled by oars, sails, poles, and towlines. The keelboat served as the expedition's main vessel until the spring of 1805, when it was returned to St. Louis.

What You'll Learn
The keelboat was built in Pittsburgh in 1803
The keelboat used by Lewis and Clark for their expedition was built in Pittsburgh, Pennsylvania, in 1803. The boat was constructed according to detailed specifications by Meriwether Lewis, who also supervised its construction. The keelboat was 55 feet long and 8 feet wide, with a shallow draft and a 32-foot-high mast that could be lowered. It featured a forecastle at the bow and an aftercastle at the stern, with a cabin inside the latter. The hold had a capacity of 12 tons, and the deck had 11 benches for the oarsmen. The keelboat could be propelled by oars, sails, poles, and towlines.
The construction of the keelboat did not go smoothly. Lewis was dissatisfied with the progress, as the boatbuilder was tardy and quarrelsome, causing delays in the work. Lewis had to spend most of his time in Pittsburgh at the boatyard to hasten the construction. Despite the challenges, the keelboat was completed on August 31, 1803, and Lewis set sail that very afternoon, travelling down the Ohio River to meet up with Clark near Louisville, Kentucky, in October 1803.
The keelboat served as the main vessel for the Lewis and Clark Expedition until the spring of 1805, when it was returned to St. Louis. The expedition covered approximately 10,600 miles in total, with 85% of the journey, or over 9,000 miles, travelled by boat. The keelboat was instrumental in helping Lewis and Clark explore and document the newly acquired western portion of the United States after the Louisiana Purchase.

It was designed by Meriwether Lewis
The boat used by Meriwether Lewis and William Clark for their expedition was a keelboat, built in Pittsburgh in 1803. Lewis, who was a captain in the U.S. Army, designed the boat himself, providing detailed specifications for its construction. The keelboat was 55 feet long, with an 8-foot beam, and a shallow draft. It had a 32-foot mast that could be lowered, and could carry a headsail and a square-rigged sail. The boat was also equipped with oars, and had a 10-foot-long deck at the bow that served as a forecastle. A raised aftercastle of the same length contained a cabin. The hold of the keelboat had a capacity of 12 tons.
Lewis ordered the construction of the keelboat in May 1803, to be built according to his specifications. However, when he arrived in Pittsburgh, he found that the boatbuilder had just started work and that it would take six weeks to complete the boat. This caused concern for Lewis, as he wanted to set off before the summer drought lowered the water level of the Ohio River. Despite his worries, Lewis had to spend most of his time in Pittsburgh at the boatyard, as the builder was tardy, quarrelsome, and often drunk, causing delays in the construction.
The keelboat was the main vessel for the Lewis and Clark Expedition until the spring of 1805, when it was returned to St. Louis. The expedition covered approximately 10,600 miles, with 85% of the journey, or over 9,000 miles, travelled by boat. The keelboat was crucial for the expedition's success, allowing Lewis and Clark to explore and document the newly acquired western territory of the United States after the Louisiana Purchase.

The keelboat was the expedition's main vessel until 1805
The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was a United States expedition to explore and detail the newly acquired western portion of the country after the Louisiana Purchase. The expedition, led by Captain Meriwether Lewis and Second Lieutenant William Clark, set out from Camp Dubois, Illinois, on May 14, 1804, and travelled approximately 10,600 miles, with 85% of the journey—over 9,000 miles—completed by boat.
The keelboat was the expedition's main vessel until the spring of 1805. Built in Pittsburgh in 1803, the keelboat was constructed according to detailed specifications by Meriwether Lewis. The boat was 55 feet long, with an 8-foot beam, and a shallow draft. It could be propelled by oars, sails, poles, and towlines, and was manned by a crew of eleven oarsmen. The keelboat was used to travel down the Ohio River to Louisville, Kentucky, in October 1803, and then up the Missouri River the following year.
The keelboat played a crucial role in the expedition's journey, allowing them to transport equipment and provisions, as well as navigate the waterways of the western territories. However, by the spring of 1805, the expedition switched to canoes and pirogues, which were more suitable for the upcoming leg of the journey. The keelboat was sent back to St. Louis with the returning party on April 6, 1805, while the rest of the expedition continued overland to the Pacific Ocean.

The mast was 32 feet high and could be lowered, and the boat could carry a headsail and a square-rigged sail. The hold had a capacity of 12 tons, and it had 11 benches for the oarsmen.
The keelboat could be propelled by oars, sails, poles, and towlines. When using the setting poles, the crew would put the poles in the bottom of the river and push off while walking from the bow to the stern. Towlines were used by men, horses, or oxen to pull the boat. The ability to utilise various methods of propulsion allowed the expedition to navigate the challenging waters of the Missouri River and beyond.
The keelboat played a crucial role in the success of the Lewis and Clark Expedition, enabling them to transport equipment and provisions, as well as facilitating their interactions with Native American tribes and the exploration of the newly acquired western territories.
