Welcome to 420 Sailing

This website is to support all those interested in 420 sailing in Ireland. The 420 dinghy is an ISAF International Class and two-person dinghy for young sailors.

The 420 offers great development for sailors in the two-person disciplines – most of the World’s top sailors sailed in this class and easily moved on to succeed in other classes, and enjoy Olympic and big boat careers.

The 420 Class Association is the National Class and organises training and events across Ireland for sailors of all abilities.
