Designed by the collaborative team of Ian Howlett and Rob White, this compact dinghy represents a modern approach to accessible sailing. Built by Topper International since 2011, the Topaz Uno utilizes advanced TRILAM polyethylene construction, offering exceptional durability while keeping maintenance requirements minimal compared to traditional fiberglass dinghies. At just over 12 feet in length with a modest beam, this single-handed dinghy strikes an excellent balance between stability and performance. The fractional sloop rig with free-standing mast simplifies rigging and reduces setup time, making it particularly appealing for sailing schools, youth programs, and recreational sailors seeking hassle-free sailing. The daggerboard configuration provides versatility across varying water depths while maintaining good upwind performance. With its lightweight displacement of 132 pounds, the Topaz Uno is easily transported and launched, opening up numerous sailing venues from protected harbors to inland lakes. The generous sail area relative to displacement delivers responsive performance in light to moderate conditions, while the capsize screening formula indicates this boat is purpose-built for protected waters rather than open ocean sailing. This dinghy excels as a day sailor for coastal waters, training vessel, or recreational boat for sailors wanting an uncomplicated yet engaging sailing experience.
