The TOPCAT K1 is the flagship and at the same time the largest catamaran in the TOPCAT fleet. The 18-foot Cat is one of the fastest swordless catamarans in the world. It combines innovative design and superiority and follows the well thought-out TOPCAT concept. In 2014 the boat was completely redesigned and relaunched.
The Classic configuration often represents the entry into TOPCAT sailing: A classic fun, family and holiday catarman; despite its 18 feet, easy to control even by beginners. Sailing schools use the K1 Classic due to its large amount of space on the boat for teaching and rental. Options such as reinforced hulls with keel shoes, as well as the sepcial trampoline with ultra longlasting Tenara yard, have been specially developed for sailing schools and protect the material for different skill levels and wind conditions.
