The original Spark 15 / Dart 15 was designed in 1979 by Rodney March, who also designed the Olympic Tornado Class catamaran. In 2005 the Dart 15 was renamed the 'Sprint 15'.
The Dart 15 is car toppable and very easy to rig. It can be sailed single handed with the main sail only, or in 'sport' mode with jib and trapeze. The Dart 15 has a strong class association with many organised events / regattas throughout the UK. It is also ideal for two sailors e.g father and son/daughter, which makes an ideal family starter catamaran.
Dart 15s are great fun to race and old boats are as competitve as new boats with the one class design. Second hand boats range from £750 to £4,000, and are a good investment as they always in demand and have a good resale value.
