Coastal changed the order of starts to let the "slower" boats get away well before the "faster" ones. Both to give the little guys a spectacle to see and also to give them an hour extra sailing before the wind faded overnight. It's been well received.
In a point to point race there might not be a downwind leg so it's presumptuous to say the no-extras division will be slower.
And there's not a lot of difference between an extra's boat pulling up a gennaker to a no-extra's boat changing to a big floppy jib or poling out as far as boat handling goes
