About
Each year the class issues each registered boat a set of IHC sail buttons. When an owner buys a new sail they have it measured and record the IHC certificate number against a button here. Unused buttons expire at year end and cannot be carried forward (Rule G.2.4). Boats racing in 2+ RCA territories across 7+ events may apply for 2 extra buttons (Rule G.2.4c).
