OK maybe this is a simplistic question but:

Scenario :

Beat to windward in a Force 3-4, flatish water, standard production 21st century cruiser/racer fractionally rigged

Dilemma:

If you have a choice between an overlapping 120% genoa sheeted around the shroud or a smaller say 100% blade jib sheeted to barber haulers inside the shroud.

Lets assume the blade will get you close to the speed the polar diagram predicts. Will you get anything more from the 120% genoa ?

Which do you go for ?

The spreader length is an interesting point.

On a beamier boat the shroud would presumably hit the deck further out and the spreader would be longer as a result you can't sheet as close inboard. You don't get anywhere near the 10 degree sheeting angle.

So on an older boat(eg a 12metre, contessa, sigma 38 that sort of thing) which is probably not going to be as broad you can get away with the overlapping genoa and still make a good VMG. On a more modern design with a flatter broader hull (TP52, most modern cruiser racers etc) you are going to do better by going for a non overlapping headsail sheeted close to the centre line...

That would definitely explain what I'm see with our Hanse 430.
