It would not add much if you are cruising but will add something if you are racing. It has not to do with the long Bowsprit because on Figaro II they do the same (as in other boats). For what I can understand they don't use it in very strong winds neither in very light ones. They don't use it also when they are trying to go as downwind as they can. They use it in all other conditions even if some use it more than others. Some movies will give you a better information:
This one is not a good example he is just showing off
These are good examples:
Pelicano, what you say about this?
Edit: I did not saw Erick post about this subject. I do not agree that the use of a staysail with a spinnaker in what regards racing is only useful on the mini racers but on the mini racers, or in any boat with a big spinnaker pole, it will be more effective. Well, I don't know any racer with a pole as big in proportion with its size as a mini-racer so Erick is right in pointing that it is specially useful on those boats.
