What she can't do is "luff" - ie change course with the intent to force the other boat off course. If the intent is to sail the course she would sail in the absence of the other boat, then there isn't a problem in the rules.

Obviously not clear enough: because I'm afraid that's not the case. The windward boat is still the windward boat and must keep clear of the leeward boat. Its just that if the leeward boat establishes the overlap from behind she may not sail above her proper course.

The rules are clear enough Rupert. The (presumably overtaking) assy boat in you scenario has no rights over the windward boat until it has sailed through its lee and broken the overlap. This is basically how its always been for boats overtaking to leewards. The big change in the rules compared to the Golden Age of dinghy sailing (when it was allowed to be fun) is the situation for an overtaking boat passing to windward which now needs to break the overlap to deny the leeward boat luffing rights compared to the old "mast abeam" rule.

Maybe I'm picturing my angles wrongly, but the scenario where an assy boat goes from sailing from well below to well above the line of the boat going straight is pretty common on a small lake in gusty weather.

70 degrees would be quite remarkable Rupert... I don't know of an asymettric boat that can usefully gybe more than 100 degrees on the run even in the lightest of air, so very unlikley to be more than about 20 or 30 dgrees difference in angle between strong gust and lull.

Sailing a proper course which involves another boat changing course isn't the same as luffing, it has to be remembered. Hence the Assy reachy boat being able to come from below and behind and still force the other boat to change course.

The problem I have is where the assy boat has cought a gust, and is sailing lower than the ordinary boat, and goes behind and below. The wind then drops, and the proper course of the assy boat then changes by 70 degrees, or some such, as it now wants to luff up to keep the kite filling, so forcing the ordinary boat which it has just ducked to massively change course too.

The rules have no problem with it, as far as I can see, and I guess it is just another peril of handicap racing, but it seems wrong, somehow.

Yes, with caveats. And note that regardless of how the overlap is established, it is the proper course of the leeward boat. So in the case of an asymetric boat sailing an angle that brings them into conflict with a symmetric (or non-spinnaker) boat sailing the rhumb line, the asymetric can continue to sail her hot angle as long as she gives the windward boat sufficient time and room to keep clear. Note that no allowance has to be made for the windward boat being idiotic and bleating about their proper course or the overlap being established from behind, as long as no contact is made.

IE you can't sail underneath someone and then push them up, but if someone sails down onto you, then you can push them up.  Yes?
