ships developed sleek hulls with the addition of a 'whaleback' forward in an attempt to provide shelter to the fishdeck, steam engines were replaced by modern powerful marine diesel technology and at the final stage of this evolution of the side winder trawler is Ross Tiger. Being built in the 1950s she was constructed the decade prior to Grimsby's introduction to the modern 'stern trawlers' and welded ship construction that changed the profile of the trawler forever. She is also old enough to retain the traditional character, brass and woodwork that is similar to the heritage and atmosphere of trawlers long before her time, but was lost by the 1960s. Ross Tiger was the first of twelve new trawlers for one of Grimsby's most prolific trawler owners. She entered service fresh from the yards of Cochrane and Sons, Selby, Yorkshire to become part of the 'middle water' fleet for Ross Trawlers Ltd. The trawlers of the town took their crews away in what is recognised as 'the most dangerous job in the United Kingdom' and scoured the ocean floors for deep sea fish, with a particular focus on cod and haddock. Haddock, regarded as a cleaner fish by Grimbarians, was preferred locally although the rail links from the town allowed for Grimsby fish to supply the nation, particularly with links to the south and the great Billingsgate Fish Market of London. The Cod Wars spelt the end of the life of many Grimsby trawlers, though some were saved from the breakers' yard to become standby vessels used for offshore oil rigs. The Ross Tiger was among those fortunate few, changing hands in 1985. However, the aging vessels were soon to be redundant and Ross Tiger was looking at the breakers' yard or yet another change of hands. Once again, Ross Tiger proved lucky. She was purchased by a museum trust to become the star attraction of her home town's Fishing Heritage Centre, and restored to her fishing day glory. An article in the Grimsby Telegraph on 14 July 1992 quoted the local council as they made it clear that Ross Tiger "will remain as a fitting monument to the people who sailed out of what was once known as the world's premier fishing port". Guided tours of the vessel show visitors the unique spaces aboard and demonstrate how various pieces of equipment aboard this traditional design of trawler were used.
