Isaac Todd was built at Québec in 1811 for John McTavish, a partner in the North West Company (NWC).

Isaac Todd then sailed to China where she picked up a cargo of tea for the British East India Company (EIC).

Isaac Todd first appears in Lloyd's Register in 1812, with F. Smith, master, M'Tavish & Co, owner, and trade London–Quebec.

Racoon therefore sailed on to Fort Astoria while Phoebe and Cherub set off to search for the USS Essex, which was capturing British whalers at the Galapagos Islands and off the Peruvian coast.

Before Racoon arrived at Fort Astoria on 30 November 1813,[1] the North West Company had completed a deal with the Pacific Fur Company that since British ships would be imminently arriving to "take and destroy everything American on the Northwest coast," that they would purchase the assets, for a third of their value.

[1] Captain Joazen Smith sailed Isaac Todd from Whampoa Anchorage on 14 March 1815, bound for England, carrying a cargo of tea for the EIC.

The Register of Shipping for 1821 shows her master as Dawson, changing to Threw, her owner as Mount, and her trade as London–Quebec.

[8] Lloyd's List reported on 6 November 1821 that Isaac Todd, Captain Thew, and two other vessels had wrecked in Gaspee Bay.
