Dare I say a Firefly – 1948 Olympic singlehander. Most team racing fleets also have storm sails, for when the wind gets up. So you can sail single-handed or two-up. Indeed, I have a pet theory that you could sail the whole Olympics in a fleet of Firefly – Full rig for the men’s single-hander, mens and womes crewed, small rig for the women singlehander, then male and female team racing!
