Jim, what did a cherub weigh in those days, what was the spinnaker area and the approximate equivalent handicap?

I don't doubt what you say, it's just on paper what the others are saying about a 200 is right I think.

so a 200 is off near as makes no difference the same PY but the boat is 30-35% heavier.

1050? Even for a short boat, I can't see how that is right, its about the same as a Mk2 Comet Trio?

I'd say that the Cherub even in those days would be faster than. a 200, by how much though is debatable. The 200 is a foot longer but a lot heavier and also carries less sail.

Is that enough to make it profitable to sail the angles? Jim's experience certainly indicates that it was, but was it only just? If it was only just you'd expect that from time to time a square running boat would get there first - and according to Jim they didn't.

I think it's looking like it might be "only just" about profitable for a 200 to sail the angles, but it works more often than it doesn't. It would be interesting to repeat some proper tests with 200 and also Guy Winders experiment with a Fireball. You would hope we've learned a thing or three in the 25 years that have passed since someone really looked at this is scientific detail in the public eye (I'm sure people have been playing on and off since then).
