Not an assumption at all, an opinion based on my personal observation.
Tactics do exist, they are just less important of course, which means less opportunity to make for not being the ideal weight for the day, or for having a marginally slow boat.

Windward-Leeward courses date back well before the invention of asymmetric spinnakers by the way, I have a good book written in the early fifties which mentions that racing in Snipes in America was often some races triangles, some races W-L.

I don't necessarily want W-L every time, just more often, instead of some of the 'harbour tours'.

Not really. Most symmetric keelboat classes have been doing predominantly W/L regattas for a couple of decades now.

I've been relearning the long-lost art of reaching in the last couple of years, having joined a class that still does triangles and I quite enjoy it. It is certainly however more of a test of boat-handling than of tactics.

My understanding regarding windward/leeward courses were that it came from the vast growth in fleet size of boats with aysmmetric spinnakers. SB3s, J80s and white boat fleets at the Hamble winter series and Warsash Spring series will normally do windward leeward courses, maybe set with inner and outer loops in a trapezoid course.
 
The reason for windard/leeward is that the greatest gains are made on down wind legs. The RYA race management courses also emphasise this point and encourage race officers to ensure that the down wind leg is square to the wind and has an offset for tidal conditions.  A race officer should aim for a 50/50 split in port and starboard tracks down the run.
 
Top sailors work very hard downwind to stay in the pressure and to work the waves. Average sailors just seem to aim for the mark and pass time on the run ensuring they don't risk a capsize. It is generally far harder to spot the shifts on the down wind leg, hence why this happens.
 
In one of the last Hamble Winter series races last year, a large wind shift after the start reduced the course to a series of reaches. It became processional for the fleet and at times because of bunching, the size of the fleet and the variation in boat speeds, it became close to dangerous. 
 
And I also agree that a blasting reach is great fun but more place changes occur on the beats and runs.

It also self-restricted the size and shape of kite used, as it needed to be small enough to allow you to make the wing mark, yet big and powerful enough to help you go deep on the runs.  In the cherubs this resulted in 3/4 hoist kite that had big "foldable" shoulders on single spreader rigs, which were really good.  It also meant that the hull shapes had to be more "all-rounders" rather than thin, flat, ironing boards.
 
Bring them back is what I say.  We did olympic courses at Weymouth regatta in 2009 and is was brilliant fun.


Actually, the 14's never stopped racing sausage-triangle (apart from special cases like the last worlds where there were practical constraints due to the location), for very much those reasons - there's a real skill in flying a big kite tight on a reach, it makes sure the kite designs stay "general purpose" for normal club racing, and up and down the same windward/leeward 6 times get boring anyway. Until recently it was actually a class rule that major events included reaching legs - that came out of the rules per se as ISAF wanted them limited to equipment-related matters only, but to have reaches is still formal class policy

Not sure where the windward/leeward fad came from - think it was originally one of those attempts to make sailing a media sport via short-course racing, and windward/leeward was part of that?

And to the original topic - changing the rules isn't going to happen and isn't needed, and of course fast assymetrics have to observe the rules like anyone else. But collisions are in no-one's interest, and it's just common sense to avoid them. It's like those trucks with signs saying "if you can't see my mirrors I can't see you" - a good general rule for anyone going upwind is that if you haven't seen the heads of the crew of a boat coming downwind (especially one with a big kite, but could be anything), assume they haven't seen you and shout early! (which was Dad's handy tip for his daughter doing her first Bloody Mary in her Topper recently!)

If going as fast as possible was that important, we'd all be sailing boards.


I don't know why people assume that having reaches or sailing a  fast boat, means tactics don't exist.

You still have a lot of choice in the angle you sail and can definately overtake people through good decisions and positioning. Sure it might be harder because you can be struggling to keep the stick in the air, but that just adds to the challenge and the difficulty in balancing risk and reward.

We'd all be sailing Kites, there's a video somewhere on youtube where a kite beats and rsX and an 18 footer.

It's incredible

I'm always quietly amused by all the people who reckon that the future of sailing is to sail the fastest possible boats on their slowest points of sailing... I'd quite fancy doing Bob's fetch/blast once in a blue moon... You need some serious skill to overtake in that, not just getting lucky with a windshift... How about doing it with staggered starts, 3 laps each, and the best single lap time wins? That would be a real test of who can sail fast.

Triangle-sausage is what I prefer for most symetric racing, a gybe mark does add some focus to the reaches!
I find w-l often a bit dull in keelboats, personally.
But if it's not possible to set a decent triangle with two kite legs, due to fixed marks or shifting wind, then maybe w-l  is less likely to be a procession.
