The Irwin 28 Mk III represents the final evolution of Ted Irwin’s highly successful 28foot platform, a vessel that epitomized the "big small boat" philosophy of the late 1970s and early 1980s. Built in St. Petersburg, Florida, the Mk III was a significant departure from the original 1970 Mk I and the mid70s Mk II. While it utilized the same fundamental hull shape, the Mk III featured a modernized deck mold, an enlarged cockpit, and a redesigned interior that capitalized on the boat's massive 10foot, 1inch beam. This model was specifically engineered to dominate the coastal cruising market, offering a blend of shallowwater accessibility and interior volume that few competitors in the 28foot class could match at the time.
