The SPARTA 1/4 TON sailing boat is a small racing sailboat that was designed and built in the late 1970s. It was specifically designed to compete in the Quarter Ton Cup, a prestigious international sailing competition for boats with a displacement of 0.25 tons.

The SPARTA 1/4 TON was designed by Peter Norlin, a renowned Swedish yacht designer, and was built by the Swedish boatyard, SPARTA Marin AB. It was first launched in 1978 and quickly gained popularity among sailors due to its excellent performance and competitive edge.

The boat features a sleek and narrow hull design, which allows it to cut through the water with minimal resistance. It has a length of approximately 7.5 meters (25 feet) and a beam of around 2.5 meters (8 feet). The sail area is typically around 30 square meters (323 square feet), providing enough power to propel the boat at high speeds.

The SPARTA 1/4 TON is known for its agility and responsiveness, making it a favorite among racing enthusiasts. It is designed to be crewed by a small team of 3-4 people, with specific roles assigned to each crew member to optimize performance. The boat's lightweight construction and efficient sail plan allow it to excel in a wide range of wind conditions.

Throughout its production, the SPARTA 1/4 TON underwent several modifications and improvements to enhance its performance. Different versions of the boat were built, each with slight variations in design and features. These modifications aimed to optimize the boat's speed, stability, and overall handling characteristics.

The SPARTA 1/4 TON achieved considerable success in international racing competitions, including the Quarter Ton Cup. It became particularly popular in Europe, where it competed against other quarter-ton class boats from various manufacturers.

While the SPARTA 1/4 TON is no longer in production, it remains a beloved classic among sailing enthusiasts. Many of these boats can still be found actively racing or being used for recreational sailing. The SPARTA 1/4 TON's legacy as a competitive and well-designed racing sailboat continues to be appreciated by sailors worldwide.
