The four-bladed propeller was replaced by a slightly smaller three-bladed model, and the bilge keels, previously added to reduce the tendency to roll, were replaced by a heavy external oak keel for the same purpose. The five-masted schooner sail-plan was replaced by four masts, two of which were square-rigged. With the refit complete, "Great Britain" went back into service on the New York run. After only one further round trip she was sold again, to Antony Gibbs & Sons, which planned to place her into England–Australia service.
