"The 5 male/5 female cut is fair enough, but note that the dinghy appears twice: one singlehanded and one double handed. The keelboat is also doublehanded, so this initial 5/5 proposition already starts with two doublehanded monohulls..."

Aren't the keelboat classes triplehanded?

I'd be shocked if they reduce to just one singlehanded dinghy.
