The Westerly 21 represents the final evolution of the 21.5foot cruising platform designed by the renowned naval architect Laurent Giles for the British yard Westerly Marine Construction. Originally launched in 1970 as the Westerly Warwick, the model was rebranded and significantly updated in 1977 as the Westerly 21. While it shares the same robust hull and twinkeel configuration as its predecessor, the 21 introduced a modernized interior and refined deck hardware to compete in the evolving smallcruiser market of the late 1970s. Despite its compact dimensions, the vessel was engineered as a "miniature Centaur," mirroring the design language and seaworthiness of its larger, worldfamous siblings. It remains a staple of the secondhand market for coastal cruisers seeking a trailerable, tidefriendly vessel with surprisingly high internal volume.
