Green Flash Microtonner

Green Flash Microtonner

Description

The Green Flash Microtonner (also known as the Green Flash Microtonner 19 or simply Microtonner 19 in class contexts) is a high-performance, trailerable racing sailboat designed for competitive one-design or international micro-class racing. It's particularly appealing to amateur boat builders who want to race seriously, as it combines straightforward home construction with strong performance in a worldwide class (likely tied to the International Micro Class or similar rules, emphasizing lightweight, planing-capable designs under ~19 ft). This is a modern, sporty daysailer/racer rather than a cruiser—think fast, responsive, and fun for club racing, with minimal accommodations (open or very basic interior for 2–4 people day sailing). It's lightweight, with a lifting keel for easy trailering and shallow-water access.
