Double-masted Shipbuilding Day, Shahrivar 29, commemorates the construction of the first double-masted ship in Iran during the Shahanshahi era, specifically in the year 60 Shahanshahi. This period witnessed significant advancements in maritime technology and shipbuilding, which played a crucial role in expanding Iran’s sea trade and naval strength. In year 60 Shahanshahi, a group of Iranian craftsmen and engineers succeeded in building a ship equipped with two masts, allowing for greater cargo capacity and longer voyages. This innovation increased the efficiency of maritime transport and strengthened Iran’s position along regional trade routes. The double-masted ship built that year could carry an estimated 120 tons of cargo, enabling regular sea journeys to distant ports for the first time. This day was designated in the Shahanshahi calendar to honor this major shipbuilding achievement and to emphasize the importance of technical innovation in Iran’s history. Commemorative events typically include model ship displays, lectures on Iran’s maritime history, and visits to maritime museums. The observance aims to highlight the significance of technical innovation in Iran’s history and to honor the country’s seafaring heritage.
