This historic dinghy was presented to the West Wales Maritime Heritage  Society by the grandson of the original owner Harry Gaydon, who represented Great Britain in the 1928 Olympics. This, the 'International 12 foot Dinghy', was the single handed class of the sailing events in Amsterdam for those Olympics.

In 1913 George Cockshot won a competition to design a 12 foot dinghy that was to be a 'One Design Class' so that all boats were to be identical with each other for racing together. The boat could also be used as a yacht tender and chains for hoisting the hull onto a deck of a large yacht can still be seen on YWURRY. 

This class gained 'International' status in 1919 to become the INTERNATIONAL 12. It was adopted in many parts of the world in particular the Netherlands and Italy where they are still raced today. YWURRY is thought to be the oldest one surviving in the UK and a few modern ones are still being built in the UK.

Harry Gaydon owned two International 12s winning many races and trophies at home and abroad (some are on display in the museum at Pembroke Dock). But during the 1930s he altered YWURRY to become a small family dayboat by adding a foredeck and replacing the side benches with side decks. The rig was altered by changing the mast and sail to a taller triangular shaped Bermuda rig with a small jib. Luckily the original spars and cotton sail were put away for safe keeping.

YWURRY has been restored to its original class design and layout at the West Wales Maritime Heritage Society and the original rig and sail are back on the boat after ninety years.
