The event was established in 2008. Each year the event runs during the second week-end of the May half term bank holiday. The event location in 2013, 2014 and 2017 was Conwy Quay Marina, for 2015 it was at Plas Heli in Pwllheli, Gwynedd and for 2019 it was all undercover at the Anglesey Showground.
2016 and 2018 was spent visiting other established events like the RYA Dinghy Show, The Jersey Boat Show and quite a few others. And now since 2019, the National Boat Show for Wales has come to the Isle of Anglesey and is focusing on boats and Watersports that can access the water via the numerous slipways.
