Twenty-one young sailors, including five from South Wales, will be training in Pwllheli this morning ahead of the Optimist European Championships.
The team are representing Great Britain in the international sailing competition, which will be held in Pwllheli for the first time this July.
The championship hasn't been held in British waters for more than 30 years, with the Optimist junior sailing class widely regarded as the breeding ground for future international sailing success.
Over 90% of sailors at London 2012 raced Optimists as juniors, including Team GB medalists Hannah Mills, Saskia Clark, Iain Percy, Andrew Simpson and Luke Patience.
The Championships themselves get underway on Friday 17 July, with a total of five days of racing before the prizes are presented on Thursday 23 July.
Some 255 sailors from 37 nations, including from outside Europe, will be racing on Cardigan Bay.
