Baron of Renfrew (ship) was exempt from the high taxes on imported timber. She was built by Charles Wood, Anse du Fort, Quebec, Canada, on his own account. She followed the construction of a similar disposable ship, the barque "Columbus" built the year before. On August 23, 1825 under the command of captain Matthew Walker the ship left Quebec with a crew of 25 men and a cargo of 9000 tons timber (probably ship and cargo weight, both timber) bound for London, England.

Cargo ship four days. These ships allowed the Allies to replace sunken cargo vessels at a rate greater than the Kriegsmarine's U-boats could sink them, and contributed significantly to the war effort, the delivery of supplies, and eventual victory over the Axis powers.
