About the International 806 Sailboat

Built during the late 1970s, this 26-foot sailboat emerged from International Marine's efforts to create an affordable yet capable cruising vessel for the growing recreational sailing market. Despite limited documentation surviving from this era, the International 806 represents the practical design philosophy that characterized many production boats of its time. The 806 appears well-suited for coastal cruising and day sailing, with proportions suggesting a focus on comfort and stability over pure performance. Like many boats from International Marine's lineup, it likely features a moderate displacement hull designed to balance seaworthiness with ease of handling for amateur sailors. While comprehensive specifications remain elusive, the 806's reputation among owners points to a sturdy, no-nonsense cruiser capable of weekend adventures and short coastal passages. The boat's design reflects the practical needs of sailors seeking reliable transportation rather than cutting-edge performance, making it an interesting option for those drawn to classic late-70s sailing characteristics. For prospective buyers researching the International 806, the limited available data underscores the importance of thorough physical inspection and surveying, as individual boat condition will be the primary factor in evaluating these aging vessels.
