I know the weakness's in Portsmouth. I race under it. And yes there are weakness's.

However I think that we could be trading one system with weakness that can be adjusted to another system.

I'm not totally against it. I just think it needs to be looked at very seriously and figure out if it improves results or might be actually worst.

And yes, Given a set of rules, A boat can be designed to "beat" the system. I'm not saying it's been done. But someone perhaps hasn't put the time into it to make that happen. Leave it to a bunch of yanks to screw up a good system.

F18 rating under schrs was 1.01 (2 decimal places)

when we changed the system to 3 dp we also changed the "fulcrum" boat - that is the boat all other boats are calcualted against to be the F18; the rating also becamse 1.005.

In the future (well my plan was when I was chair) was that the F18 rating will NEVER change; all boats will move around this boat as the formula is changed as developments happen.

The reason we chose the F18 was because it was sailed most widely world wide and so logic dictates using it as the boat we measure all other boats against.

The F18 is currently sailed by the best sailors and so it will show, to the best practical way, how a well sailed boat will perform and thus define the rating base. There are lots of boats of different designs that all measure the same under SCHRS (we assume maximum efficiency plates). These boats have their goot points (for example Shockwave down wind; Wildcat is good upwind; but under SCHRS it averages out as differing boats win the big regattas).

If the top competitors in the N20 / I20, F18 and F16 (and pick as many as you like) all sailed the same courses at the same event; I would expect the F18 to win as the World champ will be of higher quality.

If you could clone Gashby and Bundy to sail all the boats over a spread of conditions and courses you would get draws.
