Download Boat Record:


The oldest one-design Class still racing in the UK (according to the 'Guiness Book of Yachting').
More than 40 boats were built before WWI.
Despite the fact the original plans were drawn on a cigarette pack, a thorough accounting exists for all boats built since 1899. Boat #2, built in 1899, is still sailing.(New boats can still be ordered).
The present day fleet is based at Trearddur Bay, Cardington Bay, and Abersoch and on the Mersey at Wallasey (Wales).
