The Dublin Bay Waterwag lays claim to being the oldest one-design sailing boat in the world. Founded as a class in 1887, the design was modified in 1900 and the rules are essntially unchanged since then.

The Waterwags have a very active class association and are keenly raced in Dun Laoghire harbour, near Dublin.

Classic Sailboats can supply the Dublin Bay Waterwag as a complete package including spars, foils, sails, trailer and covers, or finished to individual requirements
