Fishing schooners became obsolete during the 1930s, displaced by motor schooners and trawlers. Salt cod, the main fishing industry in the North Atlantic had been surpassed by the fresh fish industry requiring faster vessels. In 1933, "Bluenose" was invited to the World's Fair in Chicago, stopping in Toronto on her return voyage. In 1935, "Bluenose" sailed to Plymouth after being invited as part of the Silver Jubilee of King George V. During her visit, she took part in a race with schooner-yachts, specifically designed for racing. "Bluenose" came third. On her return trip to Nova Scotia, "Bluenose" encountered a strong gale that lasted for three days. Enough damage was done to the schooner that "Bluenose" was forced to return to Plymouth to effect repairs. She was made seaworthy enough to sail to Lunenburg where further repairs were done. In 1936, "Bluenose" had diesel engines installed and topmasts removed to allow the schooner to remain on the fishing grounds year-round.
