A product of Thompson Boat Company, the 850 is a modest sailboat that reflects the builder's broader reputation for producing accessible, entry-level watercraft aimed at recreational sailors. While detailed specifications for this model are limited, the 850 appears to be a compact daysailer or small cruiser well suited to protected waters, making it an appealing option for beginners or casual sailors looking for an uncomplicated time on the water. Thompson built a range of fiberglass boats throughout the mid-to-late twentieth century, and their sailboat offerings generally prioritized ease of handling and affordability over high-performance sailing characteristics. The 850 likely follows this philosophy, offering a manageable platform for inland lakes, bays, and calm coastal sailing rather than demanding offshore passages. For those researching the 850 as a potential purchase, it may appeal most as a low-maintenance weekend boat or a stepping stone for newer sailors building their skills. Prospective buyers are encouraged to seek out existing owners and inspect any available examples carefully, as documentation and parts support for older Thompson models can be harder to come by than for more widely produced designs.
