Designed by renowned naval architect Tony Castro and built by Marine Glass in the UK, this 25-footer represents a thoughtful approach to compact coastal cruising. With 160 hulls launched starting in 1986, the Spring 25 carved out a respectable niche in the competitive small cruiser market of the late 1980s. Castro's design emphasizes seaworthiness and stability through its wing keel configuration, which provides excellent tracking while reducing draft to just three feet for gunkholing in shallow waters. The fractional sloop rig delivers balanced sail handling, making this boat particularly appealing to couples or small families seeking manageable performance under sail. At 4,500 pounds displacement with over a third of that weight in ballast, the Spring 25 offers reassuring stability for coastal passages and weekend cruising. The fiberglass construction ensures durability, while the conservative comfort ratio of 15.8 suggests a relatively stiff, quick motion in a seaway—more lively than plodding, but well-suited to her intended coastal cruising role. With a respectable sail area to displacement ratio, the Spring 25 should provide spirited performance in moderate conditions. The capsize screening value indicates good stability characteristics, making this Castro design a sensible choice for sailors prioritizing safety and manageability over racing performance.
