Most catamarans have shrouds placed far aft, and no backstay. That means the boom cannot swing out as far as on typical monohulls, and therefore the jibe angle is smaller. The boat has a narrower range of downwind sailing angles. For this reason, and a few other architectural ones, cat sailors don’t often sail dead downwind, at least not with the main up. It’s a big sail, with lots of roach in the leech; long, heavy battens; and, on many boats, a traveler that’s 10 or more feet long. When you jibe one of these accidentally in 25 knots, it’s like lifting a cat by the tail: You discover new things that can’t be learned any other way.
